*Title: * Towards Efficient and Effective Privacy-Preserving Machine
Learning

*Abstract:* The past decade has witnessed the fast growth and tremendous
success of machine learning. However, recent studies showed that existing
machine learning models are vulnerable to privacy attacks, such as
membership inference attacks, and thus pose severe threats to personal
privacy. Therefore, one of the major challenges in machine learning is to
learn effectively from enormous amounts of sensitive data without giving up
on privacy. In this talk, I will discuss my efforts in addressing this
challenge for solving two important problems: high-dimensional sparse
learning and nonconvex optimization. I will first introduce a
knowledge-transfer framework that achieves improved privacy and utility
guarantees for privacy-preserving sparse learning approaches. I will then
present an efficient stochastic algorithm for solving nonconvex
optimization problems with privacy guarantees.  Lastly, I will discuss some
ongoing and future research.

*Bio: *Lingxiao Wang is a Ph.D. candidate in the Department of Computer
Science at the University of California, Los Angeles, advised by Professor
Quanquan Gu. Previously he obtained his MS degree in Statistics at the
University of Washington. Lingxiao’s research interests are broadly in
machine learning, including privacy-preserving machine learning, low-rank
matrix learning, high-dimensional graphical models, and federated learning.
He is a recipient of Rising Stars in Data Science (2021) from the
University of Chicago.
