Exploring the fascinating realm of linear regression and matrix factorization applied to S&P 500 data, with the goal of deciphering stock market trends and uncovering potential investment ...

Abstract: In this paper, we investigate blind source separation for audio signals based on multichannel nonnegative matrix factorization (MNMF) of magnitude spectrograms in a linear demixed domain.

One of the main uses of QR decomposition A=QR is in solving the linear least squares problem Ax=b. In order to solve this problem, the only access we need of Q is the ability to apply it (or its ...
