Non-Gaussian Component Analysis

New Ideas, New Proofs, New Applications

Panov, Vladimir

In this article, we present new ideas concerning Non-Gaussian Component Analysis (NGCA). We use the structural assumption that a high-dimensional random vector X can be represented as a sum of two components - a lowdimensional ...
