Decouple Searching from Training: Scaling Data Mixing via Model Merging for Large Language Model Pre-training

Shengrui Li, Fei Zhao, Kaiyan Zhao +6

Determining an effective data mixture is a key factor in Large Language Model (LLM) pre-training, where models must balance general competence with proficiency on hard tasks such a…

BEACON: Bayesian Optimal Stopping for Efficient LLM Sampling

Guangya Wan, Zixin Stephen Xu, Sasa Zorc +4

Sampling multiple responses is a common way to improve LLM output quality, but it comes at the cost of additional computation. The key challenge is deciding when to stop generating…

COMPASS: Enhancing Agent Long-Horizon Reasoning with Evolving Context

Guangya Wan, Mingyang Ling, Xiaoqi Ren +3

Long-horizon tasks that require sustained reasoning and multiple tool interactions remain challenging for LLM agents: small errors compound across steps, and even state-of-the-art…

Memory in Large Language Models: Mechanisms, Evaluation and Evolution

Dianxing Zhang, Wendong Li, Kani Song +4

Under a unified operational definition, we define LLM memory as a persistent state written during pretraining, finetuning, or inference that can later be addressed and that stably…

Through the Theory of Mind's Eye: Reading Minds with Multimodal Video Large Language Models

Zhawnen Chen, Tianchun Wang, Yizhou Wang +4

Can large multimodal models have a human-like ability for emotional and social reasoning, and if so, how does it work? Recent research has discovered emergent theory-of-mind (ToM)…
