Continual Learning with Graph Reservoirs: Preliminary experiments in graph classification
Domenico Tortorella, Alessio Micheli · 2024
Continual learning aims to address the challenge of catastrophic forgetting in training models where data patterns are non-stationary.Previous research has shown that fully-trained graph learning models are particularly affected by this issue.One approach to lifting part of the burden is to leverage the representations provided by a training-free reservoir computing model.In this work, we evaluate for the first time different continual learning strategies in conjunction with Graph Echo State Networks, which have already demonstrated their efficacy and efficiency in graph classification tasks.Research partly supported by PNRR, PE00000013 -"FAIR -Future Artificial Intelligence Research" -Spoke 1, funded by European Commission under the NextGeneration EU programme.35
