avalanche.evaluation.metrics.ForwardTransfer

class avalanche.evaluation.metrics.ForwardTransfer

The standalone Forward Transfer metric. This metric returns the forward transfer relative to a specific key. Alternatively, this metric returns a dict in which each key is associated to the forward transfer. Forward transfer is computed as the difference between the value recorded for a specific key after the previous experience has been trained on, and random initialization before training. The value associated to a key can be updated with the update method.

At initialization, this metric returns an empty dictionary.
