New research uses Fisher-Rao metric to prevent LLM model collapse

A new paper proposes using the Fisher-Rao metric to analyze the dynamics of training large language models (LLMs) with synthetic data. The research addresses the issue of "model collapse," where LLMs forget the true data distribution when trained recursively on synthetic data. The authors establish theoretical guarantees for the minimum ratio of human data required to prevent this collapse, demonstrating that this ratio is different from previous estimates derived using the Euclidean metric.

IMPACT Provides theoretical insights into maintaining LLM training stability with synthetic data, potentially improving future model development.

    Preventing Model Collapse: A Fisher-Rao Perspective on the Dynamics of Training with Synthetic Data

    arXiv:2609.18878v1 Announce Type: new Abstract: Large Language Models (LLMs) are now routinely trained using synthetic data, since high-quality human data has been exhausted by the ever increasing needs of larger and larger models. However, recursive training on synthetic data fr…
