CS Seminar | Learning with Big Data by Incremental Optimization of Performance Measures

Start Date: December 1, 2015
End Date: December 1, 2015

By Professor Zhi-Hua Zhou
Department of Computer Science & Technology, Nanjing University, China

A popular approach to achieve a strong learning system is to take the performance measure that will be used for evaluation as an optimization target, and then accomplish the learning task by an optimization procedure. Many performance measures in machine learning, however, are unfortunately non-linear, non-smooth and non-convex, leading to difficult optimization problems. With big data, the optimization becomes even more challenging because of the concerns of computational, storage, communication costs, etc. Particularly, it becomes almost impossible to collect all data at first and then perform optimization, and it is desired to be able to optimize performance measures incrementally, without accessing the whole data. In this talk we will introduce some studies along this direction.
