Orchestra: Unsupervised Federated Learning via Globally Consistent Clustering

ICML 2022spotlight

Federated learning is generally used in tasks where labels are readily available (e.g., next word prediction). Relaxing this constraint requires design of unsupervised learning techniques that can support desirable properties for federated training: robustness to statistical/systems heterogeneity, s…

Libri-Adapt: a New Speech Dataset for Unsupervised Domain Adaptation

ICASSP 2020accepted

This paper introduces a new dataset, Libri-Adapt, to support unsupervised domain adaptation research on speech recognition models. Built on top of the LibriSpeech corpus, Libri-Adapt contains 7200 hours of English speech recorded on mobile and embedded-scale microphones, and spans 72 different domai…
