CoLD: Counterfactually-Guided Length Debiasing for Process Reward Models in Mathematical Reasoning

Congmin Zheng, Jiachen Zhu, Jianghao Lin +6

Process Reward Models (PRMs) play a central role in evaluating and guiding multi-step reasoning in large language models (LLMs), especially for mathematical problem solving. Howeve…

daVinci-LLM:Towards the Science of Pretraining

Yiwei Qin, Yixiu Liu, Tiantian Mi +12

The foundational pretraining phase determines a model's capability ceiling, as post-training struggles to overcome capability foundations established during pretraining, yet it rem…

Data Darwinism Part II: DataEvolve -- AI can Autonomously Evolve Pretraining Data Curation

Tiantian Mi, Dongming Shan, Zhen Huang +6

Data Darwinism (Part I) established a ten-level hierarchy for data processing, showing that stronger processing can unlock greater data value. However, that work relied on manually…

Data Darwinism Part I: Unlocking the Value of Scientific Data for Pre-training

Yiwei Qin, Zhen Huang, Tiantian Mi +5

Data quality determines foundation model performance, yet systematic processing frameworks are lacking. We introduce Data Darwinism, a ten-level taxonomy (L0-L9) that conceptualize…

Generative AI Act II: Test Time Scaling Drives Cognition Engineering

Shijie Xia, Yiwei Qin, Xuefeng Li +11

The first generation of Large Language Models - what might be called "Act I" of generative AI (2020-2023) - achieved remarkable success through massive parameter and data scaling,…
