The overlap–add method is an efficient way to evaluate the discrete convolution of a very long signal with a finite impulse response (FIR) filter where h[m] = 0 for m outside the region [1, M].The concept here is to divide the problem into multiple convolutions of h[n] with sho...

The architecture is capable of learning how to decode monkey's arm movements using a gradient descent-based algorithm that allows tuning the parameters used for the convolution kernels of the adaptive decoding filter to minimize the mean-squared error between the intended output and the prediction. ...
