Title:	Sparse Optimization Algorithms for Machine Learning
Time & Venue:	2019.7.9 15:30-16:30 N204
Abstract:	I will begin my talk with an introduction to some basic statistical and deep learning models, including support vector machine, logistic regression and deep neural networks, and discuss their relationship and training algorithms. I will then focus on a special class of optimization algorithms for obtaining sparse machine learning models. I will explain why existing polular techniques such as compressed sensing has not been much used in deep learning and will then present some of our recent theoretical and numerical results on this topic.
