Talk title: Anomaly Detection for Out-of-Distribution and Open Set Detection

Abstract: Standard supervised classification assumes a closed iid world: Test data come from the same distribution as the training data, and they contain only the same classes as the training data. How can we detect when these assumptions are violated? One approach is to train an anomaly detector that checks each test query to see if it falls within the region of competence of the classifier. If the query is anomalous because of a change of distribution and particularly if the change introduces a novel class, the anomaly detector should reject the query. This talk will review the current state of the art in this area with a focus on deep anomaly detection. A key challenge is that whereas in standard anomaly detection the engineered feature space can provide a useful distance measure, in the representations learned by deep learning, distances are much less reliable.

Talk title: Efficient and Reliable Deep Learning at Scale

Abstract: The rapid growth of modern neural network (NN) models’ scale generates ever-increasing demands for high computing power of artificial intelligence (AI) systems. Many specialized computing devices have been also deployed in the AI systems, forming a truly application-driven heterogeneous computing platform. This talk discusses the importance of computing system and paradigm designs in AI applications. We first discuss the design philosophy of heterogeneous AI computing systems, and then present several hardware friendly efficient NN model design techniques. We also extend our discussions to distributed systems and federated learning, and briefly introduce the automation of the co-design flow, e.g., neural architecture search. A research roadmap of our group in the relevant topics is given at the end of the talk.

Talk title: Using graph methods to understand diseases and repurpose drugs

Abstract: This talk will discuss some advanced bioinformatics methods and software that can be used to greatly facility the analysis and understanding of high-throughput omics data. Issues will include drawbacks of commonly used approaches for pathway analysis, a method comparison and benchmarking results, and other issues related to data analysis. The seminar will include live demonstrations on several data sets aiming at understanding the disease and identifying drugs suitable for repurposing in COVID-19.
