Learn to optimize language model training for the averaged model returned, rather than the final model, to improve performance

advanced Published 25 Jun 2026
Action Steps
  1. Formulate optimizer design as an optimal-control problem to improve iterate-average estimator performance
  2. Use exponential moving average of training iterates to return an averaged model
  3. Apply optimal-control techniques to optimize training for the averaged model
  4. Test and evaluate the performance of the optimized averaged model
  5. Compare the results with traditional training methods to measure improvement

Title: Training for the Model You Return: Improving Optimization for Iterate-Averaged Language Models

Abstract:
arXiv:2606.25086v1 Announce Type: cross Abstract: Many modern Language Model (LM) pipelines return an averaged model, such as an exponential moving average of the training iterates, rather than the final iterate itself. This raises a fundamental question: given that we will return an iterate average, how should we change training to improve the performance of this average? We study this question by formulating optimizer design for the iterate-average estimator as an optimal-control problem. In a
