AlgoTune: Can Language Models Speed Up General-Purpose Numerical Programs?

NeurIPS 2025poster

Despite progress in language model (LM) capabilities, evaluations have thus far focused on models' performance on tasks that humans have previously solved, including in programming (SWE-Bench) and mathematics (FrontierMath). We therefore propose testing models' ability to design and implement algor…

Git Re-Basin: Merging Models modulo Permutation Symmetries

ICLR 2023top-5%

The success of deep learning is due in large part to our ability to solve certain massive non-convex optimization problems with relative ease. Though non-convex optimization is NP-hard, simple algorithms -- often variants of stochastic gradient descent -- exhibit surprising effectiveness in fitting…

Mo' States Mo' Problems: Emergency Stop Mechanisms from Observation

NeurIPS 2019poster

In many environments, only a relatively small subset of the complete state space is necessary in order to accomplish a given task. We develop a simple technique using emergency stops (e-stops) to exploit this phenomenon. Using e-stops significantly improves sample complexity by reducing the amount o…
