摘     要：In the conventional statistical framework, the goal is to develop optimality theory and optimal statistical procedures, where the optimality is understood with respect to the sample size and parameter space. However, in many contemporary applications, nonstatistical concerns such as computational, communication, and privacy constraints associated with the statistical procedures come to the forefront. A fundamental question in Data Science is: How to make optimal statistical inference under these nonstatistical constraints?

In this talk, we discuss some recent advances on differentially private learning, distributed learning under communication constraints, and interplay between statistical accuracy and computational efficiency in a few specific settings. The results show some interesting and novel phenomena and point to directions that are worthy further investigation.
