Venue: Boardroom, Dao Yuan Building

摘要：

In this talk, I will present two research topics.

First, I will revisit the integer programming (IP) problem, which plays a fundamental role in many computer vision and machine learning applications. We propose a novel and versatile framework called Lp-box ADMM, based on the idea that the binary constraint is equivalent to the intersection of two continuous constraints. It reformulates the IP problem into an equivalent continuous optimization with only one non-convex constraint, which can be efficiently optimized by the standard ADMM algorithm. The Lp-box ADMM method is applicable to any integer programming tasks, such as image segmentation, clustering, model compression, hash code learning, etc. Second, I will give an overview of the literature of secure artificial intelligence, especially on adversarial examples. Based on the basic concepts of adversarial examples, I propose a general framework, of which most existing works of adversarial examples can be covered as special cases. Our several works under this framework will also be introduced, including black-box attack, physical attack, sparse attack, robust training, and adversarial detection, etc.

Above works were published in TPAMI and CVPR.
