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. ...
That is, , where the action of on the incident field will in general be in the form of a convolution. As is simply the mathematical description of T, inherits the symmetries of T. Thus, because of the cylindrical and mirror symmetries of the target and given an incident field , the ...
