Demand forecasting models have many common challenges: large quantities of SKUs or series to predict, partial history or irregular history for many SKUs,  multiple locations with different local or regional demand patterns, and cold-start prediction requests from the business for new products. The list goes on. 

 

Time Series in DataRobot, however, has a diverse range of functionality to help tackle these challenges. For example:

  • Automatic feature engineering and creation of lagged variables across multiple data types, as well as training dataset creation
  • Diverse approaches for time series modeling with text data, learning from cross-series interactions and scaling to hundreds or thousands of series
  • Feature generation from an uploaded Calendar of Events file specific to your business or use case.
  • Automatic backtesting controls for regular and irregular time-series.
  • Training dataset creation for irregular series via custom aggregations.
  • Segmented modeling, hierarchical clustering for multi-series models, multimodal modeling, and ensembling.
  • Periodicity and stationarity detection, and automatic feature list creation with various differencing strategies.
  • Cold start modeling on series with limited or no history
  • And insights for all of the above.

 

About this Accelerator

In this first installment of a three-part series on demand forecasting, this accelerator provides the building blocks for a time-series experimentation and production workflow. 

 

The dataset consists of 50 series (46 SKUs across 22 stores) over a 2 year period with varying series history, typical of a business releasing and removing products over time.

 

What you will learn  

  • Inspect and handle common data and modeling challenges
  • Identifies common pitfalls in real-life time series data
  • Helper functions to scale experimentation with the tools mentioned above and more.
