Query: Does the Adam Optimizer Exacerbate Catastrophic Forgetting?   Catastrophic forgetting remains a severe hindrance to the broad application
of artificial neural networks (ANNs), however, it continues to be a poorly
understood phenomenon. Despite the extensive amount of work on catastrophic
forgetting, we argue that it is still unclear how exactly the phenomenon should
be quantified, and, moreover, to what degree all of the choices we make when
designing learning systems affect the amount of catastrophic forgetting. We use
various testbeds from the reinforcement learning and supervised learning
literature to (1) provide evidence that the choice of which modern
gradient-based optimization algorithm is used to train an ANN has a significant
impact on the amount of catastrophic forgetting and show that-surprisingly-in
many instances classical algorithms such as vanilla SGD experience less
catastrophic forgetting than the more modern algorithms such as Adam. We
empirically compare four different existing metrics for quantifying
catastrophic forgetting and (2) show that the degree to which the learning
systems experience catastrophic forgetting is sufficiently sensitive to the
metric used that a change from one principled metric to another is enough to
change the conclusions of a study dramatically. Our results suggest that a much
more rigorous experimental methodology is required when looking at catastrophic
forgetting. Based on our results, we recommend inter-task forgetting in
supervised learning must be measured with both retention and relearning metrics
concurrently, and intra-task forgetting in reinforcement learning must-at the
very least-be measured with pairwise interference.
