A multi-series framework for demand forecasts in E-commerce

no code implementations31 May 2019 Rémy Garnier, Arnaud Belletoile

However, due to the short nature of sales times series in E-commerce, univariate methods don't apply well.

High dimensional VAR with low rank transition

no code implementations2 May 2019 Pierre Alquier, Karine Bertin, Paul Doukhan, Rémy Garnier

We propose a vector auto-regressive (VAR) model with a low-rank constraint on the transition matrix.
