Robust Principal Component Analysis using Density Power Divergence

no code implementations24 Sep 2023 Subhrajyoty Roy, Ayanendranath Basu, Abhik Ghosh

On the other end of the spectrum, robust PCA algorithms solving principal component pursuit or similar optimization problems have high breakdown, but lack theoretical richness and demand high computational power compared to the M-estimators.
