Charlestown, MA 02129 When: 6:00 (Doors), 6:30 (talk) Logistics: - Indigo is located on the second floor of the North Building in Hood Business Park at 500 Rutherford Ave, Charlestown, MA. - There is plenty of free parking in the front lot outside of the building (attendees will not be towed; no parking pass or car identification is needed), and we are a 5 minute walk from the Sullivan Square T Stop. - The space capacity is 300. We will, as usual, admit on a first-come, first-serve basis until full Talk Abstract: Graph databases have become much more widely popularized in the recent year. By representing highly connected data in a graph, we have access to a host of graph native algorithms that depend on and exploit the relationships between our data. Computing and storing graph metrics can add strong new features to nodes, creating innovative predictors for machine learning. Using algorithms designed for path finding, centrality, community detection, and graph pattern matching, we can begin to rely less on inflexible, subject-driven feature engineering. In this session, Brandy Freitas will cover the interplay between graph analytics and machine learning, improved feature engineering with graph native algorithms, and outline the current use of graph technology in industry.

  • Interpretable Representation Learning for Visual Intelligence

    IBM Research Cambridge

    PLEASE BRING an ID ! Schedule: 6:00 - 6:30 Food and Drinks 6:30 - 7:15ish Session 7:15 - 8:00 Schmooze ~~~~~~~~~~~~~~~~~~~~~~~~ Abstract: Recent progress of deep neural networks in computer vision and machine learning has enabled transformative applications across robotics, healthcare, and security. However, despite the superior performance of the deep neural networks, it remains challenging to understand their inner workings and explain their output predictions. My research has pioneered several novel approaches for opening up the “black box” of neural networks used in vision tasks. In this talk, I will first show that objects and other meaningful concepts emerge as a consequence of recognizing scenes. A network dissection approach is further introduced to automatically identify the emergent concepts and quantify their interpretability. Then I will describe an approach that can efficiently explain the output prediction for any given image. It sheds light on the decision-making process of the networks and why they succeed or fail. Finally, I will talk about ongoing efforts toward learning efficient and interpretable representations for video understanding, generative adversarial networks, and learning in virtual environment. ---- Bio: Bolei Zhou recently received his Ph.D. at MIT CSAIL.

  • Skip-Thought Vectors & Optimization


    Schedule: 6:00 - 6:30 Food and Drinks 6:30 - 7:00 Session I 7:00 - 7:30 Session II 7:30 - 8:00 Schmooze ~~~~~~~~~~~~~~~~~~~~~~~~ Session I: Skip-Thought Vectors for Financial Document Topical Analysis Abstract: In this talk, I will discuss a consulting project that I have been a part of with an insurance company in developing topic clustering across financial documents to help analysts find information. An avalanche of financial information is published every day, making it very difficult to manually process and find relevant documents. Using Skip-Thought Vectors, where sentences that share semantic and syntactic properties are mapped to similar vectors, one can train an end-to-end deep neural network for topical analysis. Using such a model, we created a system that auto-processes new documents every day, auto-highlights topics of interest to the company and allows them to quickly discover the competitive landscape of the market sector.

He has authored research papers in machine learning in the fields of robotics, finance and natural language processing, and presented his findings in multiple software conferences, most recently at CVPR in Honolulu. ~~~~~~~~~~~~~~~~~~~~~~~~ Session II: Everything You Wanted to Know About Optimization Abstract: In recent years the use of adaptive momentum methods like Adam and RMSProp has become popular in reducing the sensitivity of machine learning models to optimization hyperparameters and increasing the rate of convergence for complex models. However, past research has shown when properly tuned, using simple SGD + momentum produces better generalization properties and better validation losses at the later stages of training. In a wave of papers submitted in early 2018, researchers have suggested justifications for this unexpected behavior and proposed practical solutions to the problem. This talk will first provide a primer on optimization for machine learning, then summarize the results of these papers and propose practical approaches to applying these findings.
