Llemma: An Open Language Model for Mathematics

ICLR 2024poster

We present Llemma, a large language model for mathematics. We continue pretraining Code Llama on the Proof-Pile-2, a mixture of scientific papers, web data containing mathematics, and mathematical code, yielding Llemma. On the MATH benchmark Llemma outperforms all known openly released models, as we…

OpenWebMath: An Open Dataset of High-Quality Mathematical Web Text

ICLR 2024poster

There is growing evidence that pretraining on high quality, carefully thought-out tokens such as code or mathematics plays an important role in improving the reasoning abilities of large language models. For example, Minerva, a PaLM model finetuned on billions of tokens of mathematical documents fro…

Large Language Models are Human-Level Prompt Engineers

ICLR 2023poster

By conditioning on natural language instructions, large language models (LLMs) have displayed impressive capabilities as general-purpose computers. However, task performance depends significantly on the quality of the prompt used to steer the model, and most effective prompts have been handcrafted b…

STEVE-1: A Generative Model for Text-to-Behavior in Minecraft

NeurIPS 2023spotlight

Constructing AI models that respond to text instructions is challenging, especially for sequential decision-making tasks. This work introduces a methodology, inspired by unCLIP, for instruction-tuning generative models of behavior without relying on a large dataset of instruction-labeled trajectorie…

You Can’t Count on Luck: Why Decision Transformers and RvS Fail in Stochastic Environments

NeurIPS 2022accept

Recently, methods such as Decision Transformer that reduce reinforcement learning to a prediction task and solve it via supervised learning (RvS) have become popular due to their simplicity, robustness to hyperparameters, and strong overall performance on offline RL tasks. However, simply conditioni…

Learning Domain Invariant Representations in Goal-conditioned Block MDPs

NeurIPS 2021poster

Deep Reinforcement Learning (RL) is successful in solving many complex Markov Decision Processes (MDPs) problems. However, agents often face unanticipated environmental changes after deployment in the real world. These changes are often spurious and unrelated to the underlying problem, such as backg…
