English(EN) Bilevel optimization for data-driven learning of Koopman embeddings using kernel-based autoencoders

新的核方法学习Koopman嵌入,可与ANN媲美

研究人员开发了一种新的基于核的方法,可以直接从数据中学习有限维Koopman嵌入,称为基于核字典学习的扩展动态模式分解(EDMD-kDL)。该方法结合了双层优化和配置方法,同时学习核字典和Koopman近似。在包括海表温度预测和视频数据分析在内的各种数值实验中,EDMD-kDL的表现与最先进的基于人工神经网络(ANN)的方法相当或更优。该方法旨在可扩展至大型数据集。 AI

影响 这种新的基于核的方法为学习Koopman嵌入提供了一种可解释且可扩展的ANN替代方案,有望推动复杂系统的数据驱动建模。
