It's All Training: A Fully Synthetic Single-Stage Recipe for LLMs

arXiv:2609.37891v1 Announce Type: cross Abstract: Current pre-training datasets are derived from web crawls, with all their issues, and were not designed to support mid- and post-training pipelines--...

Rethinking LLM-as-a-Judge: Representation-as-a-Judge with Small Language Models via Semantic Capacity Asymmetry

arXiv:2601. 22588v2 Announce Type: replace-cross Abstract: Large language models (LLMs) are widely used as reference-free evaluators via prompting, but this "LLM-as-a-Judge" paradigm is costly, opaque, and sensitive to prompt design.

Evaluation of pre-trained models for pedagogical assessment of novel AI-assisted educational questions

The study evaluates how well pre‑trained models can classify the Bloom level of AI‑generated educational questions, a task that is crucial for ensuring pedagogical quality. Traditional machine‑learning models perform poorly on out‑of‑distribution data, whereas transformer and large‑language models achieve higher accuracy, especially after feature‑engineering techniques such as text splicing and appending learning objectives. Retraining the models yields the most significant performance gains across all datasets.
