avalanche.evaluation.metrics.EpochR2

class avalanche.evaluation.metrics.EpochR2

The average R2 over a single training epoch. This plugin metric only works at training time.

The R2 will be logged after each training epoch by computing the number of correctly predicted patterns during the epoch divided by the overall number of patterns encountered in that epoch.
