Buying Data of Unknown Quality: Statistical Information Procurement Auctions
Yuchen Hu, Martin J. Wainwright, Stephen Bates
We study statistical parameter estimation in the setting of data markets when providers differ in both provision costs and estimation-relevant data quality. We define a cost-per-in…
Optimal Targeting in Dynamic Systems
Yuchen Hu, Shuangning Li, Stefan Wager
Modern treatment targeting methods often rely on estimating a conditional average treatment effect (CATE) using machine learning tools. While effective in identifying who benefits…
A Bias-Correction Decentralized Stochastic Gradient Algorithm with Momentum Acceleration
Yuchen Hu, Xi Chen, Weidong Liu +1
Distributed stochastic optimization algorithms can simultaneously process large-scale datasets, significantly accelerating model training. However, their effectiveness is often hin…
Estimating Treatment Effects under Algorithmic Interference: A Structured Neural Networks Approach
Ruohan Zhan, Shichao Han, Yuchen Hu +1
Online user-generated content platforms allocate billions of dollars of promotional traffic through algorithms in two-sided marketplaces. To evaluate updates to these algorithms, p…
