WebSep 3, 2024 · The utility matrix is factorized such that the loss between the multiplication of these two and the true utility matrix is minimized. One commonly used loss function is mean-squared error. Essentially, each user and item is projected onto a latent space, represented by a latent vector. WebWe updated the code to support the latest library. It requires cvxopt, numpy, scipy and torch. We just added the support for PyTorch-based SNMF. Packages. The package includes: Non-negative matrix factorization (NMF) [three different optimizations used] Convex non-negative matrix factorization (CNMF) Semi non-negative matrix factorization (SNMF)
