OTClean: Data Cleaning for Conditional Independence Violations using Optimal Transport

Summary: OTClean repairs datasets to enforce conditional independence (CI) constraints for fair/trustworthy ML, using optimal transport as the distortion metric. Formulates CI repair as a QCLP, then scales it via Sinkhorn-style regularized optimization for high-dimensional data while preserving utility. (summarized by gpt-5.4-mini on May 24 2026)
