Intermittent Demand Forecasting at Scale Using Meta-Modeling - Deep Auto-Regressive Linear Dynamic Systems

Explore a groundbreaking demand forecasting solution for intermittent time-series developed by Walmart in this 28-minute presentation. Discover how the meta-modeling approach combines linear dynamic systems and deep auto-regressive recurrent networks to address the challenges of predicting slow-moving item demand across Walmart stores. Learn about the solution's architecture, including explicit feature engineering, implicit feature modeling, and the Deep ARLDS network. Gain insights into scaling the model for accurate forecasts across approximately 35,000 SKUs and 250 Walmart stores. Examine the results and consider future applications of this innovative approach to granular demand predictions at scale.
