avalanche.evaluation.metrics.StreamRMSEForgetting

class avalanche.evaluation.metrics.StreamRMSEForgetting

The StreamRMSEForgetting metric, describing the average evaluation RMSE loss detected over all experiences observed during training.

This plugin metric, computed over all observed experiences during training, is the average over the difference between the RMSE result obtained after first training on a experience and the RMSE result obtained on the same experience at the end of successive experiences.

Since RMSE is to be minimized, forgetting is observed when the result is negative.

This metric is computed during the eval phase only.
