Stabilizing Gradients for Deep Neural Networks

Vanishing and exploding gradients are two of the main obstacles in training deep neural networks, especially in capturing long range dependencies in recurrent neural networks (RNNs). In this talk, we present an efficient parametrization of the transition matrix of an RNN that allows us to stabilize the gradients that arise in its training. Specifically, we parameterize the transition matrix by its singular value decomposition (SVD), which allows us to explicitly track and control its singular values. We attain efficiency by using tools that are common in numerical linear algebra, namely Householder reflectors for representing the orthogonal matrices that arise in the SVD. By explicitly controlling the singular values, our proposed svdRNN method allows us to easily solve the exploding gradient problem and we observe that it empirically solves the vanishing gradient issue to a large extent. We note that the SVD parameterization can be used for any rectangular weight matrix, hence it can be easily extended to any deep neural network, such as a multi-layer perceptron. Theoretically, we demonstrate that our parameterization does not lose any expressive power, and show how it potentially makes the optimization process easier. Our experimental results demonstrate that the proposed framework converges faster, and has better generalization, especially when the depth is large.

Massive-scale streaming analytics

Emerging real-world graph problems include: detecting community structure in large social networks; improving the resilience of the electric power grid; and detecting and preventing disease in human populations. Unlike traditional applications in computational science and engineering, solving these problems at scale often raises new challenges because of the sparsity and lack of locality in the data, the need for additional research on scalable algorithms and development of frameworks for solving these problems on high performance computers, and the need for improved models that also capture the noise and bias inherent in the torrential data streams. In this talk, the speaker will discuss the opportunities and challenges in massive data-intensive computing for applications in computational science and engineering.

Computing Architectures for Machine Perception in the Post Deep-Learning World

We are in the middle of a surge in popularity, interest and investments in artificial intelligence and neural networks. Successful demonstration of ImageNet classification with deep convolutional neural networks (DCNN), has established the viability of robust image recognition system based on very large collection of labeled images, and powerful GPUS to train the DCNN, and execute the trained classifier on computing devices with modest computing capabilities. Typically the training takes place on a centralized computer, and classification takes place on computing device connected directly to the sensor, referred as computing at the edge. Elements of the analytical framework of image recognition include convolution, shift invariance, correlation and scaling by down-sampling are easier are essential to the pooling process critical for building deep neural networks. Similar abstractions for analyzing large collection of texts, and cyber forensic data, are yet to be well established. The computing capabilities required to build ubiquitous self-aware multimodal-sensor network will entail architectural innovations beyond GPGPUs. We will review the lessons learned in the realm of video analytics and automated text analytics over the past decades and also share insights towards promising new directions. Exciting new possibilities await us, enabled by the convergence of open-source software development tools, data- sharing tools, and innovatively packaged processors with high-bandwidth memory subsystems and highly scalable networked computing.

The Promise of Machine Learning for Infrared Spectroscopic Image Analysis

A key theme in near and mid-infrared imaging data sciences is the image acquisition coupled to robust computational analysis of spatial and spectral information, to simultaneously predict shape and functional properties of complex scenes. Current capabilities allow for the rapid recording of full hyper-spectral image sets, typically 100 GB, having 10 megapixels, with each pixel containing 2000 spectral wavelengths, with an absorbance value between [0, 1], with noise levels from [10−3, 0.1]. The barriers limiting progress today then is accurate and rapid computational image analysis for the robust elucidation of spatial structure and their material properties.. This talk shall dwell on the success, and current challenges of state of the art machine learning algorithms (spectral de-noising, multi-label classification, functional un-mixing, ..). We quantify the improvement, or lack thereof, using error estimates for image classification and spectral signature recovery.

War Stories from the Bioinformatics Front

Widely accepted criteria routinely misdiagnose autoimmune diseases such as Systemic Lupus Erythematosus (SLE) and Mixed Connective Tissue Disease (MCTD). To make matters worse, these criteria fail to differentiate between these two similar diseases. We show how to achieve better accuracies on this front.
Glimpses into microbial communities reveal a diverse, dynamic and complex environment where the entities compete for nutrients, generously share functional genes, produce weapons of destruction in the form of toxins, release various metabolites and signaling molecules for sharing and communication, combine forces to fight common enemies, and much more. We discuss challenges in modeling microbiomes as predictive social networks.

An Energy-Efficient Embedded Implementation For Target Recognition In SAR Imageries

We present an energy-efficient deep learning model design, training and implementation method for the synthetic aperture radar (SAR) image classification application on a neuromorphic processor. The proposed approach adopts emerging neuromorphic computing models and hardware to achieve significant improvement in computational energy efficiency over deep learning algorithms on conventional embedded processors. A deep convolutional neural network (DCNN) is designed specifically for implementing image classification on the TrueNorth neurosynaptic processor. We have explored the DCNN model design parameters to obtain a comprehensive solution set in the energy-performance trade-off space. Using a SAR image classification dataset, evaluation results show that the proposed design and implementation approach achieves at least 20X reduction in energy-per-image-classification over one of today’s most energy-efficient conventional embedded processors. while achieving a classification accuracy of 95% and a processing throughput of 1,000 images per second.

Scalable Data Analytics: The Role of Stratified Data Sharding

With the increasing popularity of structured data stores, social networks and Web 2.0 and 3.0 applications, complex data formats, such as trees and graphs, are becoming ubiquitous. Managing and processing such large and complex data stores, on modern computational eco-systems, to realize actionable information efficiently, is daunting. In this talk I will begin with discussing some of these challenges. Subsequently I will discuss a critical element at the heart of this challenge relates to the sharding, placement, storage and access of such tera- and peta- scale data. In this work we develop a novel distributed framework to ease the burden on the programmer and propose an agile and intelligent placement service layer as a flexible yet unified means to address this challenge. Central to our framework is the notion of stratification which seeks to initially group structurally (or semantically) similar entities into strata. Subsequently strata are partitioned within this eco-system according to the needs of the application to maximize locality, balance load, minimize data skew or even take into account energy consumption. Results on several real-world applications validate the efficacy and efficiency of our approach. (Notes: Joint work with Y. Wang (Airbnb) and A. Chakrabarti (MSR).

Time & Energy Efficient Computing

Traditionally, the performance of an application has been measured by its time and memory requirements. More recently, there has been interest in a third performance metric—energy. This talk will begin by motivating the consideration of energy as a metric and then focus on two areas—data centers and big data computations—where both time to completion and energy consumption are important metrics. For data centers, we review some of our recent work in optimizing data center network topology in support of long running data aggregations and, for big data computations, we demonstrate significant time and energy improvements for large scale sequence alignment and RNA folding by enhancing the cache utilization of classical algorithms.

Credit rating of financial instruments

The credit rating of financial instruments is one of the factors that play a significant role while making investment decisions. Credit rating companies provide information about the credit stability/ transitions (deterioration/ up gradation) of the debt instruments using financial parameters, industry parameters, and external environment at quarterly intervals. In the present scenario, investment managers have to wait for quite some time to know about the credit rating stability/ transition. We propose that incorporating the market news available from different sources in almost real time along with the usual financial parameters should be able to predict the rating stability/ transition well in advance. The present work focus on incorporating sentiment scores extracted from various news sources like new aggregators like Bloomberg, Reuters, Company Web sites, Blogs etc. Depending upon the source of news a weight will be given taking into consideration trust worthiness of the source, Location of the Company information in the body of the news, Frequency of appearance. Using deep learning weights are assigned to each source. A Composite Sentiment score is computed as weighed average of the various individual news sources. This composite score is additional Input along with other financial parameters about eleven to survival analysis which in turn will forecast credit events. Our results show that Return on Capital Employed ROCE and Interest cover ratio along with sentiment scores are the best predictor variables to predict the rating stability/ transition. We tested our methodology on about three hundred companies. Most of them are from mining & textile segment as majority of downgrades and rating transitions have happened in those sectors. Back testing results show that proposed model very well predicts the credit rating stability/ transition. Without using the sentiment score and our weighing scheme the prediction accuracy of a transition was about 45% on hold out Samples (About 30 of 300) and with Financial and sentiment score it went up to about 70%. This work will be very helpful from the regulatory point of view also as one has to compute the Future value of Loan portfolio ie Credit Risk VAR. This method computes the Credit Risk VAR much accurately compared to existing methods of Credit Risk Computation.

ReactionMiner: Predicting novel metabolic pathways through subgraph mining

Chemical reactions are not random events. Two molecules react if they satisfy certain constraints, which are often structural in nature. Can we learn these structural constraints and predict the chain of reactions required to synthesize molecule B from A? The ability to predict chemical pathways between molecules is critical for several applications such as optimizing chemical manufacturing cost, understanding the functioning of enzymes, discovering novel pathways to synthesize molecules of interest and synthetic biology. In this talk, we will present a fully automated system to predict chemical pathways between molecules. We achieve this task by representing chemical molecules as graphs. Through a graph-based analysis of molecular structures, we mine the structural patterns required for a reaction to proceed. The problem of predicting pathways between two molecules is difficult because of the exponential search space that needs to be explored. By representing the chemical pathway space using subgraph patterns, we capture an abstract representation of all possibilities in the form of a reaction network and consequently, are able to efficiently predict pathways between molecules that we have never seen before. We demonstrate that our prediction algorithm can scale to thousands of reactions and answer queries in seconds. We perform extensive experiments on the largest publicly available reaction database to validate the accuracy of our predictions. The results indicate an accuracy beyond 80 % and a querying time of less than a minute. Furthermore, we conduct qualitative experiments to show that our algorithm performs consistently well in identifying naturally occurring pathways that appear within cells of living organisms.

Machine Learning in Security Analytics

The use case is based on the problem statement that despite well defined security operations centres (SOC) and SIEM tools, still the cyber breaches go either undetected or unresponded, as a function of time. The battle against evolving landscape of cyber attacks, can possibly be won by working on a non-linear equation with an empirical formula TD (Time to detect an attack) + TR (Time to respond an attack) < TA (Time for an attack to thrive), whilst the attackers have the asymmetric advantage of the first move and well orchestrated planning.
When we started working on the solution the biggest challenge was the dimensionality of the problem statement. The feature space for the desired solution was complex and highly qualitative when attack patterns are categorised into (a) known knowns, (b) known unknowns, and (c) unknown unknowns. As the Detection of Attack, is completely machine based therefore building solutions around TD was not as fuzzy as that was in case of TR, as the Response to Attack involves a fair amount of human role. The human factor brings in the challenges of language, expressions, efficiency, effectiveness as a function of 24x7, competencies, exposure, situational context, etc. while working on the attack response(s) on the fly at the time of real attack propagation. This brought us to include the machine support function and statistical correlation models into our product facilitating SOC operators to take swift & consistent actions in the event of the attack propagation. Solving this puzzle is a work in progress the accuracies are average, while we are consistently improving results in last 6 months. Though we are still building on a comprehensive machine model for the Response to Attack phase with deep learning models, alternatively to avoid product release delays, we included the mathematical computations that involve the collaborative consensus model to arrive at a risk score for every potential Indicator of Attack (IOA). The Risk Score above 8 on the scale of 10 has achieved 92% accuracy and is used for automatic block actions by most of our customers. We have integrated the Threat Hunting workflows to ease the SOC operators for the IOA that are having score less than 8, while we are working on improving various dimensions of the product.
