Python Matrix Factorization Toolbox

Python Matrix Factorization (PyMF) is a module for several constrained and unconstrained matrix factorization (and related) methods. It can be downloaded from this page http://pymf.googlecode.com/.

 

PyMF currently includes the following methods:

  • Non-negative matrix factorization (NMF)
  • Convex non-negative matrix factorization (CNMF)
  • Semi non-negative matrix factorization (SNMF)
  • Archetypal analysis (AA)
  • Simplex volume maximization (SiVM)
  • Convex-hull non-negative matrix factorization (CHNMF)
  • Binary matrix factorization (BNMF)
  • Singular value decomposition (SVD)
  • Principal component analysis (PCA)
  • K-means clustering (Kmeans)
  • CUR decomposition (CUR)
  • Compaxt matrix decomposition (CMD)
