Forecasting, Deep learning and neural networks

Insights 5

Treat public-benchmark scores of forecasting foundation models as possibly contaminated
Make a foundation or deep forecaster beat seasonal naive and ETS on your backtest first
Check that a zero-shot foundation forecaster can use your future-known drivers before expecting promotion peaks
Match a foundation model's context window to your longest seasonal cycle
Handle sparse and flat series before sending them to a mean-scaled, tokenizing forecaster
