A new research paper published on arXiv explores the fragility of high-dimensional interpolators in machine learning. The study, titled "High-Dimensional Interpolators Can Be Fragile: Heavy Tails and High-Dimensional Large Deviations," uses large-deviation methods to analyze ridgeless regression compared to ridge-regularized estimators. It reveals that while interpolating models may perform well on average, their risk can exhibit heavy-tailed behavior, meaning rare, severe errors are more probable than with regularized alternatives.

IMPACT This research suggests that current machine learning models may have unaddressed tail risks, potentially impacting applications where rare errors have significant consequences.
