avalanche.evaluation.metrics.ExperienceR2Forgetting

class avalanche.evaluation.metrics.ExperienceR2Forgetting

The ExperienceR2Forgetting metric, describing the R2 loss detected for a certain experience.

This plugin metric, computed separately for each experience, is the difference between the R2 result obtained after first training on a experience and the R2 result obtained on the same experience at the end of successive experiences.

This metric is computed during the eval phase only.

__init__()
