avalanche.evaluation.metrics.BWT

class avalanche.evaluation.metrics.BWT

The standalone Backward Transfer metric. This metric returns the backward transfer relative to a specific key. Alternatively, this metric returns a dict in which each key is associated to the backward transfer. Backward transfer is computed as the difference between the last value recorded for a specific key and the first value recorded for that key. The value associated to a key can be update with the update method.

At initialization, this metric returns an empty dictionary.
