Dirichlet Flow Matching with Applications to DNA Sequence Design

2024 · PubMed

Discrete diffusion or flow models could enable faster and more controllable sequence generation than autoregressive models. We show that na\"ive linear flow matching on the simplex is insufficient toward this goal since it suffers from …

LADDER: Language-Driven Slice Discovery and Error Rectification in Vision Classifiers

2024 · arXiv (Cornell University)

Error slice discovery is crucial to diagnose and mitigate model errors. Current clustering or discrete attribute-based slice discovery methods face key limitations: 1) clustering results in incoherent slices, while assigning discrete attributes to slices leads …
