ReBoot: Distributed statistical learning via refitting bootstrap samples
Yumeng Wang, Ziwei Zhu, Xuming He
In this paper, we propose a one-shot distributed learning algorithm via refitting bootstrap samples, which we refer to as ReBoot. ReBoot refits a new model to mini-batches of boots…

High-dimensional variable selection with heterogeneous signals: A precise asymptotic perspective
Saptarshi Roy, Ambuj Tewari, Ziwei Zhu
We study the problem of exact support recovery for high-dimensional sparse linear regression under independent Gaussian design when the signals are weak, rare, and possibly heterog…
