New Recursive Quadrature Filters enhance deep recurrent network learning

By PulseAugur Editorial · [2 sources] ·

Researchers have developed Recursive Quadrature Filters (RQFs), a novel type of complex-valued temporal filter, to improve learning in deep continuous-time recurrent networks. These filters, inspired by biological mechanisms, act as band-pass filters with adjustable frequency and bandwidth. By making each layer's input prospective, the method mitigates gradient attenuation in deep network stacks, particularly when using spatial-only backpropagation. Evaluations showed that RQF variants matched or surpassed their non-prospective counterparts across various models and tasks, including achieving high accuracy on the Speech Commands dataset with a parameter-efficient RQF.
