Heavy-Tailed Principle Component Analysis
arXiv:2603.11308v1 Announce Type: new Abstract: Principal Component Analysis (PCA) is a cornerstone of dimensionality reduction, yet its classical formulation relies critically on second-order moments and is therefore fragile in the presence of heavy-tailed data and impulsive noise.
