Nonnegative matrix factorization with side information for time series recovery and prediction
Jiali Mei, Yohann De Castro, Yannig Goude +2
Motivated by the reconstruction and the prediction of electricity consumption, we extend Nonnegative Matrix Factorization~(NMF) to take into account side information (column or row…
