FERN: Cross-Benchmark Table Retrieval for Text-to-SQL with Frozen Retrievers and Learned Ranking
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- FERN combines frozen retrievers and learned ranking to retrieve relevant tables for text-to-SQL queries across multiple benchmarks without using generative LLMs.
- Why it matters
- Matters for engineers building text-to-SQL systems over large table catalogs who need fast, efficient table retrieval without expensive model calls.
- Watch out
- Performance varies significantly across benchmarks; FERN underperforms on BEAVER and Fiben datasets, suggesting generalization challenges across different table catalog distributions.
