Forecasting hierarchical time series using deep learning in a commercial setting

Note: This article was originally written for another purpose but I thought I’d publish a copy on my blog too. A recent paper by Mancuso, Piccialli, and Sudoso, titled A machine learning approach for forecasting hierarchical time series (May 2021) showed success in hierarchical time-series forecasting in the Italian retail sector. Experiment setup The purposeContinue reading “Forecasting hierarchical time series using deep learning in a commercial setting”
