Research: Training duration impacts LLM merging effectiveness

A new research paper explores the impact of expert training duration on the effectiveness of merging multiple expert models into a single, more capable large language model. The study challenges the standard practice of merging models at their optimal validation loss, finding that certain merging methods, particularly those based on sparsification, perform better when experts are trained beyond this point. This suggests that the choice of training duration and merging method should be considered jointly for optimal results, drawing parallels to the benefits of high-variance learners in random forests. AI

IMPACT Suggests a more nuanced approach to model merging, potentially improving the efficiency and performance of combined LLMs.
