A new estimation approach for multivariate stochastic processes with potentially infinite memory has been introduced, moving beyond traditional methods that assume finite memory or sparsity. This novel technique leverages the concept of predictive states, demonstrating that the statistical complexity of estimation is tied to the intrinsic dimension of this predictive state space. The research provides theoretical guarantees for an implementation using deep neural networks and validates these findings through experimental results. AI
