Uncovering Competency Gaps in Large Language Models and Their Benchmarks
arXiv:2512. 20638v2 Announce Type: replace-cross Abstract: The evaluation of large language models relies heavily on standardized benchmarks.
Large language models are increasingly used to assist with statistical and data science tasks, but current evaluations assume the analysis goal is already defined. This paper formalizes the upstream step of Statistical Problem Formulation into two subtasks—classification of the statistical problem and identification of relevant variables—and introduces StatFormBench, a benchmark comprising 1,013 samples from five statistics textbooks and a data science case library. Across 14 open- and closed‑source LLMs, the best zero‑shot models achieve only 72.0% fine‑grained classification accuracy and 63.2% variable set overlap, with no model consistently excelling in both subtasks and limited gains from enhanced prompting strategies.

arXiv:2607. 05992v1 Announce Type: cross Abstract: Mathematical reasoning has become a central task for evaluating and tuning reasoning Large Language Models (LLMs), yet existing benchmarks remain heavily biased toward high-resource languages, with English and Chinese dominating both pre-training corpora and evaluation suites.
The paper introduces PromptNCE, a zero‑shot method that uses large language models to estimate pointwise mutual information (PMI) by framing conditional probability estimation as a contrastive task with an explicit OTHER category. The authors benchmark PromptNCE against four other prompting‑based estimators on three human‑annotated datasets, finding that PromptNCE achieves the best conditional probability estimates and Spearman correlations up to 0.78 for full PMI. A case study demonstrates the method’s utility for scoring student knowledge summaries in low‑data settings, and the authors release code and prompts for reproducibility.
Large language models (LLMs) achieve strong relation extraction (RE), but their computational demands and reliance on proprietary APIs limit deployment in resource-constrained or privacy-sensitive settings. We investigate how far small language models (SLMs) can close this gap across general-domain and literary text.
