Bases: DartsModel

N-HiTS Model (Similar to N-BEATS but faster)

Using N-HiTS as a predictor. Anomalies scores are deviations from predictions.

initialization also accepts any parameters used by: https://unit8co.github.io/darts/generated_api/darts.models.forecasting.nhits.html

Parameters:

  • window (int, optional) – rolling window size to feed into the predictor. Defaults to 10.

  • n_steps (int, optional) – number of steps to predict forward. Defaults to 1.

  • use_gpu (bool, optional) – whether to use GPU. Defaults to False.

  • val_split (float, optional) – proportion of data points reserved for validation. Defaults to 0.2.
