Statistical Inference for the Population Landscape via Moment Adjusted Stochastic Gradients
Tengyuan Liang, Weijie Su
Modern statistical inference tasks often require iterative optimization methods to compute the solution. Convergence analysis from an optimization viewpoint only informs us how wel…
On the Global Convergence of Continuous-Time Stochastic Heavy-Ball Method for Nonconvex Optimization
Wenqing Hu, Chris Junchi Li, Xiang Zhou
We study the convergence behavior of the stochastic heavy-ball method with a small stepsize. Under a change of time scale, we approximate the discrete method by a stochastic differ…
When Is the First Spurious Variable Selected by Sequential Regression Procedures?
Weijie J. Su
Applied statisticians use sequential regression procedures to produce a ranking of explanatory variables and, in settings of low correlations between variables and strong true effe…
Multiple testing when many -values are uniformly conservative, with application to testing qualitative interaction in educational interventions
Qingyuan Zhao, Dylan S. Small, Weijie Su
In the evaluation of treatment effects, it is of major policy interest to know if the treatment is beneficial for some and harmful for others, a phenomenon known as qualitative int…
