Birdie: Natural Language-Driven Table Discovery Using Differentiable Search Index

Summary: Birdie replaces the representation–index–search pipeline for NL table discovery with a differentiable search index: an encoder–decoder LM trained to map synthetic LLM-generated queries/tables to prefix-aware table identifiers, enabling deeper query–table interaction. Uses parameter-isolation for continual indexing, reducing forgetting >90% and improving accuracy +16.8% vs dense baselines. (summarized by gpt-5-mini on Feb 09 2026)
