How to Prevent Model Collapse and the Domino Effect of AI Learning from AI


TL;DR Breakdown

  • Training AI models on AI-generated data leads to distorted perceptions and inaccurate representations.
  • Using AI-generated data for training AI models raises the possibility of model collapse and deviation from the true data distribution.
  • Prioritizing human-generated data is critical to preventing AI model collapse and maintaining accuracy.

Artificial Intelligence (AI) has made remarkable strides in recent years, with advancements in machine learning models leading to significant breakthroughs. On the flip side, a concerning trend has emerged where AI models are being trained on AI-generated data. In a paper titled “The Curse of Recursion: Training on Generated Data Makes Models Forget,” researchers from prestigious institutions have shed light on the potential dangers of this practice. They warn that such an approach can lead to a phenomenon known as model collapse, where AI models lose their ability to perceive reality accurately.. This article delves into the intricacies of model collapse and highlights the importance of relying on human-generated data to maintain the integrity of AI models.

The curse of recursion leads to model collapse

Researchers from Cambridge, Oxford, the University of Toronto, and Imperial College in London have identified a troubling consequence of training AI models on AI-generated data. According to their findings, model collapse occurs when the generated data contaminates the training set of subsequent model generations. In simpler terms, AI models, being trained on polluted data, develop a distorted perception of reality. As a result, they produce inaccurate representations that deviate from the true underlying data distribution.

The problem of model collapse is not limited to a specific type of AI model. Some observe in various learned generative models and tools, including large language models (LLMs), variational auto-encoders, and Gaussian mixture models. The accumulation of generations exacerbates the issue, as the models progressively forget the original data distribution. The consequence is a simulation that is detached from reality, rendering the AI models delusional.

AI Learning from AI is a dangerous trend

The emergence of AI models being trained on AI-generated data represents a worrisome trend. As technology advances, sometimes machine learning models are intentionally trained on outputs from other AI systems. For example, language learning models (LLMs) are being trained on the outputs generated by GPT-4. Also, platforms like DeviantArt allow AI-created artwork to be published and used as training data for newer AI models. While this might seem like a step forward, it carries significant risks.

The researchers warn that the process of AI learning from AI could lead to a proliferation of model collapses. Similar to the problems encountered when attempting indefinite cloning, training AI models on AI-generated data can create a cascade of inaccuracies and distortions. As the models continue to learn from polluted data, they become further detached from the true data distribution, resulting in a loss of understanding of the real world.

Human-generated data prevents model collapse

To prevent the detrimental consequences of model collapse, it is crucial to maintain access to the original human-generated data source. The researchers propose that there is a “first-mover advantage” for training AI models. By ensuring that models are trained on real, human-produced data, the risk of distribution shift and subsequent model collapse can be mitigated.

The prevention of model collapse requires addressing the two principal causes identified in the research paper. “Statistical approximation error” is the initial cause because of the limited number of data samples. The second cause is “functional approximation error,” resulting from the improper configuration of the margin of error during AI training. These errors can compound over generations, leading to an increasing cascade of inaccuracies within the models.

Safeguarding the future of AI models

The rise of AI learning from AI presents significant challenges for the future of AI models. The phenomenon of model collapse, where AI models lose their ability to perceive reality accurately, calls for immediate attention. To prevent model collapse and ensure the integrity of AI models, it is essential to maintain access to the original human-generated data source or the ability to differentiate between machine-generated and human-produced content.
