Summary
This paper introduces DeepAR, a supervised learning approach for probabilistic forecasting that trains an autoregressive recurrent neural network jointly across many related time series. The method produces calibrated probabilistic predictions by learning from historical patterns and covariates, demonstrating strong performance on several real-world demand and retail forecasting datasets. It is primarily a methodological contribution to the machine learning and forecasting literature, with no direct connection to agricultural, nutritional, or food systems research.
UK applicability
This paper has no direct applicability to UK farming, soil health, or nutrition research; its relevance to Vitagri's Pulse Brain catalogue is limited to its potential use as a benchmark or methodological reference for time-series forecasting tasks within agricultural supply chain or demand modelling contexts.
Key measures
Probabilistic forecast accuracy (CRPS, QuantileLoss, P50/P90 quantile loss); benchmark comparisons against classical and competing deep learning methods
Outcomes reported
The paper presents and evaluates a deep learning model (DeepAR) for generating probabilistic forecasts across multiple related time series, reporting accuracy metrics on retail and demand-forecasting benchmarks.
