Provable ICA with Unknown Gaussian Noise, and Implications for Gaussian Mixtures and Autoencoders
We present a new algorithm for independent component analysis which has provable performance guarantees. In particular, suppose we are given samples of the form y=Ax+η where A is an unknown but non-singular n×n matrix, x is a random variable whose coordinates are independent and have a fourth order...
