SynthWorlds: Controlled Parallel Worlds for Disentangling Reasoning and Knowledge in Language Models

ICLR 2026poster

Evaluating the reasoning ability of language models (LMs) is complicated by their extensive parametric world knowledge, where benchmark performance often reflects factual recall rather than genuine reasoning. Existing datasets and approaches (e.g., temporal filtering, paraphrasing, adversarial subst…

RADAR: Benchmarking Language Models on Imperfect Tabular Data

NeurIPS 2025poster

Language models (LMs) are increasingly being deployed to perform autonomous data analyses. However, their data awareness—the ability to recognize, reason over, and appropriately handle data artifacts such as missing values, outliers, and logical inconsistencies—remains underexplored. These artifacts…

BLADE: Benchmarking Language Model Agents for Data-Driven Science

EMNLP 2024finding

Data-driven scientific discovery requires the iterative integration of scientific domain knowledge, statistical expertise, and an understanding of data semantics to make nuanced analytical decisions, e.g., about which variables, transformations, and statistical models to consider. LM-based agents eq…
