    Title: Improving machine learning algorithms with efficient data relevance discovery

    Abstract:

    This is the era of big data, where both challenges and opportunities lie ahead for the machine learning research. The data are created nowadays at an unprecedented pace with an unignorable cost in collecting, storing, and computing with the current scale of data. As the computational power that we possess gradually plateaus, it is an ever-increasing challenge to fully utilize the wealth of big data, where better data reduction techniques and scalable algorithms are the keys to a solution. We observe that to answer a certain query, the data are not equally important. Based on the models and the query, we provide efficient access to the numerical scores of the data points that represent their relevance in the current task. It enables us to wisely devote the computation resources to the important data, which improves the scalability and the reliability. We present our work under three applications: 1) tensor CP decomposition, 2) random-walk matrix-polynomial sparsification, where we provide an efficient access to the statistical leverage score for a faster numerical routine; and 3) matrix completability analysis, where we analyze the underlying completability structure for a more reliable estimation.

    Talk Title: Enabling Effective Performance Optimization Techniques for Heterogeneous System

    Abstract: Heterogeneous systems that couple CPUs with accelerators such as Graphics Processing Units (GPUs) and Field Programmable Gate Arrays (FPGAs) have become ubiquitous in the computing world due to their tremendous computing power. However, performance tuning for GPUs and FPGAs is not trivial. In this talk, I will first present the performance modeling and optimization for FPGAs. I will introduce an accurate performance model for OpenCL workloads on FPGAs and how we accelerate deep learning applications on FPGAs. For the second half of the talk, I will present on-chip storage and machine learning optimization techniques for GPUs. The proposed techniques leverage on compile-time and run-time techniques to improve the cache performance, register utilization, pipeline utilization and overall performance.

  • MASCLE Machine Learning Seminar: Robert Schapire (Microsoft Research NYC) - The Contextual Bandits Problem: Techniques for Learning to Make High-Reward Decisions

    Tue, Nov 14, 2017 @ 03:30 PM - 04:50 PM

    Computer Science

    Conferences, Lectures, & Seminars


    Speaker: Robert Schapire, Microsoft Research NYC

    Talk Title: The Contextual Bandits Problem: Techniques for Learning to Make High-Reward Decisions

    Series: NVIDIA Distinguished Lecture Series in Machine Learning

    Abstract: This lecture satisfies requirements for CSCI 591: Research Colloquium.

    We consider how to learn through experience to make intelligent decisions. In the generic setting, called the contextual bandits problem, the learner must repeatedly decide which action to take in response to an observed context, and is then permitted to observe the received reward, but only for the chosen action. The goal is to learn to behave nearly as well as the best policy (or decision rule) in some possibly very large and rich space of candidate policies. This talk will describe progress on developing general methods for this problem and some of its variants.


    Biography: Robert Schapire is a Principal Researcher at Microsoft Research in New York City. He received his PhD from MIT in 1991. After a short post-doc at Harvard, he joined the technical staff at AT&T Labs (formerly AT&T Bell Laboratories) in 1991. In 2002, he became a Professor of Computer Science at Princeton University. He joined Microsoft Research in 2014. His awards include the 1991 ACM Doctoral Dissertation Award, the 2003 Gödel Prize, and the 2004 Kanelakkis Theory and Practice Award (both of the last two with Yoav Freund). He is a fellow of the AAAI, and a member of both the National Academy of Engineering and the National Academy of Sciences. His main research interest is in theoretical and applied machine learning, with particular focus on boosting, online learning, game theory, and maximum entropy.

  • CS Colloquium: Dr. Brian Milch (Google) - Combining Probabilistic and Neural Approaches for Text Classification

    Tue, Nov 14, 2017 @ 05:00 PM - 06:20 PM

    Computer Science

    Conferences, Lectures, & Seminars


    Speaker: Dr. Brian Milch, Google

    Talk Title: Combining Probabilistic and Neural Approaches for Text Classification

    Series: CS Colloquium

    Abstract: This lecture satisfies requirements for CSCI 591: Research Colloquium.

    In the Semantic Signals group at Google Los Angeles, we build classifiers that label text with hundreds of human-defined categories across dozens of languages. Labeled training data is sparse, so we've found it essential to incorporate unsupervised learning methods that take advantage of unlabeled text. One of our tools is a probabilistic topic model that learns discrete "clusters" to explain word co-occurrence patterns in a large corpus, and then identifies the clusters that best explain a new document. Another tool is a neural net that learns embeddings of individual words in a continuous space. I'll discuss how these approaches play complementary roles in our text classification pipeline.


    Biography: Brian Milch is a software engineer at Google's Los Angeles office. He received a B.S. in Symbolic Systems from Stanford University in 2000, and a Ph.D. in Computer Science from U.C. Berkeley in 2006. He then spent two years as a post-doctoral researcher at MIT before joining Google in 2008. He has contributed to Google production systems for spelling correction, transliteration, and semantic modeling of text.

    Speaker: Ryan Noguchi , Director of the Space Architecture Department in the Systems Engineering Division at The Aerospace Corporation

    Talk Title: Best Practices and Lessons Learned from Model-Based System Engineering Pilot Programs

    Series: INCOSE-LA Speaker Series

    Abstract: Model Based Systems Engineering (MBSE) can offer significant benefits to organizations responsible for managing their increasingly complex enterprises. However, implementing MBSE is not a straightforward task, and there are many pitfalls along the way. An incremental approach built on solid system architecting principles, focusing on supporting major stakeholder decisions, and informed by best practices and lessons learned from previous efforts offers the best chances of success. Five years of experience in working MBSE efforts at multiple levels have produced many lessons learned and recommended best practices. This report authored by Ryan Noguchi will be briefly summarized in his presentation.

    Cost: INCOSE Members: FREE. Non-members: $10 (refreshments provided). See the registration link below.

    Biography: Ryan Noguchi is the Director of the Space Architecture Department in the Systems Engineering Division at The Aerospace Corporation.
