Autodata: An agentic data scientist to create high quality synthetic data

Ilia Kulikov, Chenxi Whitehouse, Tianhao Wu +12

We introduce Autodata, a general method that enables AI agents to act as data scientists who build high quality training and evaluation data. We show how to train (meta-optimize) s…

Reasoning over mathematical objects: on-policy reward modeling and test time aggregation

Pranjal Aggarwal, Marjan Ghazvininejad, Seungone Kim +18

The ability to precisely derive mathematical objects is a core requirement for downstream STEM applications, including mathematics, physics, and chemistry, where reasoning must cul…

Self-Improving Pretraining: using post-trained models to pretrain better models

Ellen Xiaoqing Tan, Jack Lanchantin, Shehzaad Dhuliawala +9

Large language models are classically trained in stages: pretraining on raw text followed by post-training for instruction following and reasoning. However, this separation creates…

SPICE: Self-Play In Corpus Environments Improves Reasoning

Bo Liu, Chuanyang Jin, Seungone Kim +7

Self-improving systems require environmental interaction for continuous adaptation. We introduce SPICE (Self-Play In Corpus Environments), a reinforcement learning framework where…

Stochastic activations

Maria Lomeli, Matthijs Douze, Gergely Szilvasy +7

We introduce stochastic activations. This novel strategy randomly selects between several non-linear functions in the feed-forward layer of a large language model. In particular, w…

StepWiser: Stepwise Generative Judges for Wiser Reasoning

Wei Xiong, Wenting Zhao, Weizhe Yuan +4

As models increasingly leverage multi-step reasoning strategies to solve complex problems, supervising the logical validity of these intermediate steps has become a critical resear…

Bridging Offline and Online Reinforcement Learning for LLMs

Jack Lanchantin, Angelica Chen, Janice Lan +9

We investigate the effectiveness of reinforcement learning methods for finetuning large language models when transitioning from offline to semi-online to fully online regimes for b…

Self-Challenging Language Model Agents

Yifei Zhou, Sergey Levine, Jason Weston +2

Large language models are quickly becoming the foundation for intelligent agents that are capable of using tools. However, training such agents is challenging because it requires h…

Multi-Token Attention

Olga Golovneva, Tianlu Wang, Jason Weston +1

Soft attention is a critical mechanism powering LLMs to locate relevant parts within a given context. However, individual attention weights are determined by the similarity of only…

R.I.P.: Better Models by Survival of the Fittest Prompts

Ping Yu, Weizhe Yuan, Olga Golovneva +4

Training data quality is one of the most important drivers of final model quality. In this work, we introduce a method for evaluating data integrity based on the assumption that lo…

Step-KTO: Optimizing Mathematical Reasoning through Stepwise Binary Feedback

Yen-Ting Lin, Di Jin, Tengyu Xu +11

Large language models (LLMs) have recently demonstrated remarkable success in mathematical reasoning. Despite progress in methods like chain-of-thought prompting and self-consisten…

Diverse Preference Optimization

Jack Lanchantin, Angelica Chen, Shehzaad Dhuliawala +4

Post-training of language models, either through reinforcement learning, preference optimization or supervised finetuning, tends to sharpen the output probability distribution and…
