On the Surprising Effectiveness of a Single Global Merging in Decentralized Learning
Tongtian Zhu, Tianyu Zhang, Mingze Wang +2
Decentralized learning provides a scalable alternative to parameter-server-based training, yet its performance is often hindered by limited peer-to-peer communication. In this pape…
Winners with Confidence: Discrete Argmin Inference with an Application to Model Selection
Tianyu Zhang, Hao Lee, Jing Lei
We study the problem of finding the index of the minimum value of a vector from noisy observations. This problem is relevant in population/policy comparison, discrete maximum likel…
Adaptive Projected Two-Sample Comparisons for Single-Cell Gene Expression Data
Tianyu Zhang, Jing Lei, Kathryn Roeder
We study high-dimensional two-sample mean comparison and address the curse of dimensionality through data-adaptive projections. Leveraging the low-dimensional and localized signal…
Online Estimation with Rolling Validation: Adaptive Nonparametric Estimation with Streaming Data
Tianyu Zhang, Jing Lei
Online nonparametric estimators are gaining popularity due to their efficient computation and competitive generalization abilities. An important example includes variants of stocha…
