Counterfactual Forecasting for Panel Data

Navonil Deb, Raaz Dwivedi, Sumanta Basu

We address the challenge of forecasting counterfactual outcomes in a panel data with missing entries and temporally dependent latent factors -- a common scenario in causal inferenc…

One Pipeline, Many Transformers: Pattern-Specific Imputation Specialists for Tabular Missing Data

Jacob Feitelberg, Dwaipayan Saha, Kyuseong Choi +3

Missing data in tabular datasets forces practitioners into a hard choice: deploy a general-purpose imputer that may perform poorly for the problem at hand, or wait for someone to d…

Low-Rank Thinning

Annabelle Michael Carrell, Albert Gong, Abhishek Shetty +2

The goal in thinning is to summarize a dataset using a small set of representative points. Remarkably, sub-Gaussian thinning algorithms like Kernel Halving and Compress can match t…

Cheap Permutation Testing

Carles Domingo-Enrich, Raaz Dwivedi, Lester Mackey

Permutation tests are a popular choice for distinguishing distributions and testing independence, due to their exact, finite-sample control of false positives and their minimax opt…
