Nonnegative matrix factorization with side information for time series recovery and prediction

no code implementations19 Sep 2017 Jiali Mei, Yohann de Castro, Yannig Goude, Jean-Marc Azaïs, Georges Hébrail

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 features).

Nonnegative Matrix Factorization for Time Series Recovery From a Few Temporal Aggregates

no code implementations ICML 2017 Jiali Mei, Yohann de Castro, Yannig Goude, Georges Hébrail

Motivated by electricity consumption reconstitution, we propose a new matrix recovery method using nonnegative matrix factorization (NMF).

Recovering Multiple Nonnegative Time Series From a Few Temporal Aggregates

no code implementations5 Oct 2016 Jiali Mei, Yohann de Castro, Yannig Goude, Georges Hébrail

Motivated by electricity consumption metering, we extend existing nonnegative matrix factorization (NMF) algorithms to use linear measurements as observations, instead of matrix entries.
