Research finds ChatGPT & Bard headed for 'Model Collapse'

Aug 10, 2023 - aimagazine.com
A recent research paper reveals that using model-generated content in training can cause irreversible defects in the resulting models, a phenomenon referred to as Model Collapse. This issue is particularly prevalent in Large Language Models (LLMs) such as OpenAI's ChatGPT and Google’s Bard, and can lead to a potential degeneration of the systems. The researchers argue that the introduction of machine-generated data, such as articles written by LLMs or images generated by AI, poses a significant threat to the variety and authenticity of data.

The paper suggests that the solution to this issue revolves around maintaining the authenticity of content and ensuring a realistic data distribution through additional collaborator reviews. It also emphasizes the need to regulate the usage of machine-generated data in training LLMs. As LLMs are increasingly adopted by critical industries for everyday tasks and recommendations, it becomes essential for developers to continuously improve the models while maintaining realism.

Key takeaways:

  • A recent research paper finds that using model-generated content in training can cause irreversible defects in the resulting models, a phenomenon referred to as Model Collapse.
  • This issue is particularly prevalent in models that follow a continual learning process, which adapts to dynamic data supplied sequentially.
  • Model Collapse occurs when generated data pollutes the training set of subsequent models, leading to a misperception of reality, a process also known as data poisoning.
  • The suggested solution revolves around maintaining the authenticity of content, ensuring a realistic data distribution through additional collaborator reviews, and regulating the usage of machine-generated data in training Large Language Models (LLMs).
