Cross Modal Data Discovery over Structured and Unstructured Data Lakes

Summary: CMDL enables cross-modal discovery across structured tables and unstructured documents while preserving table structure, supporting seamless pipelines across modalities. Its weakly supervised multi-modal embeddings are domain-agnostic and outperform search-based and structured-only systems on real data lakes. (summarized by gpt-5.6-luna on Jul 24 2026)
