Abstract

We introduce a novel continual learning method based on multifidelity deep neural networks. This method learns the correlation between the output of previously trained models and the desired output of the model on the current training dataset, limiting catastrophic forgetting. On its own the multifidelity continual learning method shows robust results that limit forgetting across several datasets. Additionally, we show that the multifidelity method can be combined with existing continual learning methods, including replay and memory aware synapses, to further limit catastrophic forgetting. The proposed continual learning method is especially suited for physical problems where the data satisfy the same physical laws on each domain, or for physics-informed neural networks, because in these cases we expect there to be a strong correlation between the output of the previous model and the model on the current training domain.
物理系统持续学习的多保真方法
我们介绍了一种基于多保真深度神经网络的新型持续学习方法。这种方法可以学习先前训练模型的输出与当前训练数据集上模型期望输出之间的相关性,从而限制灾难性遗忘。多保真度持续学习方法本身就能在多个数据集上显示出限制遗忘的稳健结果。此外,我们还展示了多保真度方法可以与现有的持续学习方法相结合,包括重放和记忆感知突触,以进一步限制灾难性遗忘。所提出的持续学习方法尤其适用于数据在每个域上都满足相同物理定律的物理问题,或者适用于物理信息神经网络,因为在这些情况下,我们希望上一个模型的输出与当前训练域上的模型之间存在很强的相关性。

期刊介绍: Machine Learning Science and Technology is a multidisciplinary open access journal that bridges the application of machine learning across the sciences with advances in machine learning methods and theory as motivated by physical insights. Specifically, articles must fall into one of the following categories: advance the state of machine learning-driven applications in the sciences or make conceptual, methodological or theoretical advances in machine learning with applications to, inspiration from, or motivated by scientific problems.
