Non-negative tensor factorization with applications to statistics and computer vision
Non-negative tensor factorization with applications to statistics and computer vision
We derive algorithms for finding a non-negative n-dimensional tensor factorization (n-NTF) which includes the non-negative matrix factorization (NMF) as a particular case when n = 2. We motivate the use of n-NTF in three areas of data analysis: (i) connection to latent class models in statistics, (ii) sparse image coding …
