Summary
The StockIQ "Tournament" algorithm is a selection of or combination of the available StockIQ forecast algorithms. This is an AI/ML technique known as "Ensembling." Because it is a combination of algorithms, among which selections are made, this is known as an "Ensemble" algorithm.
Settings
As the name implies, when you select the Tournament algorithm, StockIQ will run a tournament of available and enabled forecast algorithms, and select the winner.
You first need to include/eliminate the algorithms you wish to be in the 'tournament'
It operates like this:
- Run each algorithm with a matrix of settings and find the one with the lowest forecast error on a product. The measured error is against a 3-month backdated model (aka. "Holdout model"), so that we are not testing error against already-known data or "overfitting" the model.
- Once the winner is selected, we run that algorithm with all current data, so that it can generate the most up-to-date model possible.
You can view the results in the Tournament Results Dialog.
Applies To
Only time series with recurring Usage Pattern are eligible for tournament currently. Sporadic, Slow, Dead, and New items will run only the StockIQ algorithm, so no tournament is run.
