AggregationMetric

class pytorch_forecasting.metrics.AggregationMetric(metric: pytorch_forecasting.metrics.Metric, **kwargs)

Bases: pytorch_forecasting.metrics.Metric

Calculate metric on mean prediction and actuals.

Parameters

metric (Metric) – metric which to calculate on aggreation.

Methods

compute()	Abstract method that calcualtes metric
update(y_pred, y_actual)	Calculate composite metric
