ANMAT: Automatic Knowledge Discovery and Error Detection through Pattern Functional Dependencies
Summary: PFDs fuse patterns with integrity constraints to model partial-value dependencies across attributes, extending FDs. ANMAT automates PFD discovery on dirty data and flags errors via PFD violations, catching issues missed by existing approaches. (summarized by gpt-5-nano on Feb 09 2026)
