We study assortment and procurement design for a digital content platform offering both ad-supported and subscription access. Users are heterogeneous in content preferences and ad…
A Sensitivity Approach to Causal Inference Under Limited Overlap
Yuanzhe Ma, Yian Huang, Hongseok Namkoong
Limited overlap between treated and control groups is a key challenge in observational analysis. Standard approaches like trimming importance weights can reduce variance but introd…
Convergence Rate of the Join-the-Shortest-Queue System
Yuanzhe Ma, Siva Theja Maguluri
The Join-the-Shortest-Queue (JSQ) policy is among the most widely used load balancing algorithms and has been extensively studied. However, an exact characterization of the system…
A Planning Framework for Adaptive Labeling
Daksh Mittal, Yuanzhe Ma, Shalmali Joshi +1
Ground truth labels/outcomes are critical for advancing scientific and engineering applications, e.g., evaluating the treatment effect of an intervention or performance of a predic…
Minimax Optimal Estimation of Stability Under Distribution Shift
Hongseok Namkoong, Yuanzhe Ma, Peter W. Glynn
The performance of decision policies and prediction models often deteriorates when applied to environments different from the ones seen during training. To ensure reliable operatio…
Hybrid Random Features
Krzysztof Choromanski, Haoxian Chen, Han Lin +10
We propose a new class of random feature methods for linearizing softmax and Gaussian kernels called hybrid random features (HRFs) that automatically adapt the quality of kernel es…
