Fault-Tolerant Vertical Federated Learning on Dynamic Networks

no code implementations27 Dec 2023 Surojit Ganguli, Zeyu Zhou, Christopher G. Brinton, David I. Inouye

Vertical Federated learning (VFL) is a class of FL where each client shares the same sample space but only holds a subset of the features.

Towards Characterizing Domain Counterfactuals For Invertible Latent Causal Models

1 code implementation20 Jun 2023 Zeyu Zhou, Ruqi Bai, Sean Kulinski, Murat Kocaoglu, David I. Inouye

Answering counterfactual queries has important applications such as explainability, robustness, and fairness but is challenging when the causal variables are unobserved and the observations are non-linear mixtures of these latent variables, such as pixels in images.

Regenerative Particle Thompson Sampling

no code implementations15 Mar 2022 Zeyu Zhou, Bruce Hajek, Nakjung Choi, Anwar Walid

Particle Thompson sampling (PTS) is an approximation of Thompson sampling obtained by simply replacing the continuous distribution by a discrete distribution supported at a set of weighted static particles.

Iterative Alignment Flows

no code implementations15 Apr 2021 Zeyu Zhou, Ziyu Gong, Pradeep Ravikumar, David I. Inouye

Existing flow-based approaches estimate multiple flows independently, which is equivalent to learning multiple full generative models.
