A new paper proposes a factorized tabular foundation model to overcome a trade-off in current architectures.
LLMs Aim to Capture Human Irrationality in Prisoner's Dilemma
A new arXiv paper uses large language models to model how human decisions in the Prisoner's Dilemma diverge from rational choice.
RASTA framework targets style loss in machine translation
A new open-weight framework aims to preserve linguistic style in machine translation, especially for non-Western languages.
Curriculum Learning Helps LLMs Reason Implicitly, Up to a Limit
A new arXiv study finds that curriculum learning can teach large language models to reason implicitly over long horizons, but the approach still hits performance cliffs.
Demographic Injection Aims to Improve LLM Survey Simulation
A new arXiv paper tackles the challenge of making LLM-generated survey respondents reflect real population diversity.
Divergence-Based Method Aligns LLMs with Ranked Preferences
A new approach uses divergence measures to align large language models with ranked feedback, capturing richer signal than pairwise comparisons.

A new search-based approach allocates inference cache budgets across transformer layers instead of using a uniform budget.
Probing Whether Language Models Grasp Variable Roles in Code
A new arXiv study uses an established programming taxonomy to test which variable-role distinctions language models can recover from code representations.
Distributionally Robust Policies for Real-World Deployment
A new framework aims to keep learned policies from failing when deployment conditions differ from the observational data they were trained on.
Prefix-Tuning Offers Parameter-Efficient Control of LLM Outputs
A new arXiv paper describes prefix-tuning, a method that steers pretrained transformers by prepending task-specific prefixes rather than retraining all parameters.
OR-License benchmark tests LLM agents on raw client problems
A new evaluation, OR-License, asks whether LLM agents can solve operations research problems directly from original client materials, without expert reformulation.
