AI Model Collapse: Sample Selection Bias Accelerates Collapse in Siled Data

A new research paper published on arXiv explores the phenomenon of "model collapse" in AI, which occurs when recursive training on synthetic data leads to a homogenization of model outputs and erosion of distributional tails. The paper demonstrates that sample selection, often used as a remedy, can paradoxically accelerate model collapse when data is siloed and reference distributions are biased. This issue is particularly relevant in low-resource settings like healthcare or finance where data cannot be pooled. The researchers propose using collaborative proxy references from multiple silos as an initial mitigation strategy to reduce diversity degradation. AI

IMPACT Highlights potential pitfalls in AI training pipelines, especially in data-scarce or siloed environments, urging caution with synthetic data and sample selection methods.
