Thompson sampling: Precise arm-pull dynamics and adaptive inference
Qiyang Han
Adaptive sampling schemes are well known to create complex dependence that may invalidate conventional inference methods. A recent line of work shows that this need not be the case…
Long-time dynamics and universality of nonconvex gradient descent
Qiyang Han
This paper develops a general approach to characterize the long-time trajectory behavior of nonconvex gradient descent in generalized single-index models in the large aspect ratio…
Precise gradient descent training dynamics for finite-width multi-layer neural networks
Qiyang Han, Masaaki Imaizumi
In this paper, we provide the first precise distributional characterization of gradient descent iterates for general multi-layer neural networks under the canonical single-index re…
UCB algorithms for multi-armed bandits: Precise regret and adaptive inference
Qiyang Han, Koulik Khamaru, Cun-Hui Zhang
Upper Confidence Bound (UCB) algorithms are a widely-used class of sequential algorithms for the -armed bandit problem. Despite extensive research over the past decades aimed at…
Universality of regularized regression estimators in high dimensions
Qiyang Han, Yandi Shen
The Convex Gaussian Min-Max Theorem (CGMT) has emerged as a prominent theoretical tool for analyzing the precise stochastic behavior of various statistical estimators in the so-cal…
