Learning by Surprise: Adaptive Mitigation of Model Collapse in Large Language Models

arXiv:2410.12341v4 Announce Type: replace Abstract: As AI-generated content increasingly populates the web, generative AI models are at growing risk of being trained on their own outputs, a process known as AI autophagy. This feedback loop has been shown to induce model collapse, typically characterized by a loss of diversity in generated content. However, existing work offers a limited understanding of this phenomenon and relies on mitigation strategies that assume access to human-authored data. In this paper, we conduct extensive simulations across multiple datasets and LLMs to address key g

Why this matters
Why now

The proliferation of AI-generated content on the web and the increasing reliance on self-generated data for training new models make understanding and mitigating 'model collapse' critically urgent.

Why it’s important

Model collapse threatens the diversity and quality of future AI models, potentially limiting their utility and innovation, which impacts all sectors relying on generative AI.

What changes

This research provides a deeper understanding of model collapse, moving beyond existing mitigation strategies that assume access to human-authored data, and explores adaptive solutions.
