HARDEN: Constrained Evolutionary Search for Harder, Answer-Preserving Evaluation Cases

Language models are often evaluated on curated benchmarks that underrepresent the complexity of enterprise deployments. We introduce HARDEN, a constrained evolutionary search method to adapt the input of existing evaluation cases into more challenging variants while keeping their expected outputs fixed. HARDEN searches...

The Death of Schema Linking? Text-to-SQL in the Age of Well-Reasoned Language Models

This work revisits schema linking when using the latest generation of large language models (LLMs) and finds empirically that newer models are adept at utilizing relevant schema elements during generation even in the presence of large numbers of irrelevant ones.

Generalization Can Emerge in Tabular Foundation Models From a Single Table

This work systematically pre-training and evaluating on many diverse datasets and analyzes what aspects of the data are most important for building a Tabular Foundation Model (TFM) generalizing across domains to show that the number and quality of tasks one can construct from a dataset is key to downstream performance.

SQLMorph: Query Mutation and Fine-Grained Metrics for Text-to-SQL Evaluation

SQLMorph's query mutation and fine-grained metrics support debugging and better align Text-to-SQL evaluation practices with real-world deployments, and introduces a family of execution-level metrics that address the limitations of current binary measures.
