Geometric PCA of Images

open access: yesSIAM Journal on Imaging Sciences, 2013
We describe a method for analyzing the shape variability of images, called geometric PCA. Our approach is based on the use of deformation operators to model the geometric variability of images around a reference mean pattern. This leads to a new algorithm for estimating shape variability.

DP-PCA: Statistically Optimal and Differentially Private PCA

open access: yesAdvances in Neural Information Processing Systems 35, 2022
We study the canonical statistical task of computing the principal component from $n$ i.i.d.~data in $d$ dimensions under $(\varepsilon,δ)$-differential privacy. Although extensively studied in literature, existing solutions fall short on two key aspects: ($i$) even for Gaussian data, existing private algorithms require the number of samples $n$ to ...
