I recently read Skillicorn's book on matrix decompositions, and was a bit disappointed, as it was targeted to an undergraduate audience. I would like to compile (for myself and others) a short bibliography of essential papers (surveys, but also breakthrough papers) on matrix decompositions. What I have in mind primarily is something on SVD/PCA (and robust/sparse variants), and NNMF, since those are by far the most used. Do you all have any recommendation/suggestion? I am holding off mine not to bias the answers. I would ask to limit each answer to 2-3 papers.
P.S.: I refer to these two decompositions as the most used in data analysis. Of course QR, Cholesky, LU and polar are very important in numerical analysis. That is not the focus of my question though.
