New theory advances streaming PCA with uncertainty quantification
Researchers have developed new theoretical frameworks for streaming Principal Component Analysis (PCA) using Oja's algorithm. The work addresses open questions regarding convergence rates for general ranks under sub-Gau…

Online PCA phase transition depends on n/d log(d), not n/d
Researchers have identified a critical threshold for online Principal Component Analysis (PCA) algorithms, specifically Oja's algorithm. Unlike traditional PCA, which relies on the ratio of samples to dimensions ($n/d$)…

New algorithm estimates principal eigenvector with minimal data
Researchers have developed a compressed version of Oja's algorithm for estimating the principal eigenvector of a data covariance matrix. This method requires only two adaptive measurements per sample, significantly redu…
