ConceptHiPPO初始化 / High-order Polynomial Projection Operators
HiPPO
A matrix initialization method for state space models. Using a High-order Polynomial Projection Operator, it imposes special structure on recurrent matrices, enabling models to efficiently capture long-range dependencies in sequences.
