WebJan 1, 2024 · BINARY MATRIX FACTORIZATION (BMF) Bi r Matrix Factorization consists in decomposing a binary matrix as: X =W⊙HT . (1) where matrices X,W and H have r pective sizes N×M , N ×K and M ×K and whose entries are binary; ⊙ is the binary matrix product defined as Belohlavek and Vychodil (2010): Xij = K ∨ k=1 (Wik … WebJan 6, 2024 · The NBMF algorithm is a variant of the Nonnegative Matrix Factorization (NMF) algorithm (which allows C to be real-valued rather than just binary). NMF, and by extension NBMF, are useful in machine learning contexts that seek to decompose a large data set into a set of features along with a mixing matrix, e.g. learning facial features [ 11 ...
