However, these methods are unable to acquire new knowledge incrementally -- they are, in fact, mostly used only as a pre-training phase over IID data. In this work we investigate self-supervised methods in continual learning regimes without any replaymechanism. We show that naive functional regularization,also known as feature distillation, leads to lower plasticity and limits continual learning performance. Instead, we propose Projected Functional Regularization in which a separate temporal projection network ensures that the newly learned feature space preserves information of the previous one, while at the same time allowing for the learning of new features. This prevents forgetting while maintaining the plasticity of the learner. Comparison with other incremental learning approaches applied to self-supervision demonstrates that our method obtains competitive performance indifferent scenarios and on multiple datasets.", optnote="LAMP: 600.147; 600.120", optnote="exported from refbase (http://158.109.8.37/show.php?record=3704), last updated on Tue, 25 Apr 2023 15:54:14 +0200", doi="10.1109/CVPRW56347.2022.00432", file=":http://158.109.8.37/files/GTY2022.pdf:PDF" }
