Researchers have introduced Fuzzy Spectral Region Decomposition (fSRD), a novel framework designed to model highly nonlinear chaotic dynamical systems. This method automates the estimation of finite Koopman representations using multiple operators, overcoming limitations of existing Koopman methods that struggle with globally valid operators. fSRD constructs locally invariant embeddings adaptively through a global fuzzy tree model, inspired by fuzzy neural architectures, to learn system dynamics efficiently and interpretably. Empirical results on canonical chaotic systems like Lorenz and Duffing, as well as high-dimensional real-world data, demonstrate fSRD's strong predictive accuracy and expressivity across various data regimes.
