Webto the K-means clustering and also a solution to the spectral clustering. Besides NMF, other matrix factorization such as maximum margin factorization, partitioned columns based factorizations are also useful. The key defining properties of the matrix model are orthogonality and nonnegativity. Enforcing orthogonality while ignoring nonnegativity, WebHere we learn about several data reduction techniques including principal component analysis (PCA), K-means clustering, nonnegative matrix factorization (NMF) and archetypal analysis (AA). Although on the surface they seem so different, each is a data approximation technique using matrix factorization with different constraints.
