A signal processing system and method for accomplishing signal processing using a neural network that incorporates adaptive weight updating and adaptive pruning for tracking non-stationary signal is presented. The method updates the structural parameters of the neural network in principal component space (eigenspace) for every new available input sample. The non-stationary signal is recursively transformed into a matrix of eigenvectors with a corresponding matrix of eigenvalues. The method applies principal component pruning consisting of deleting the ei...


[ What is claimed is:] [1.] A neural network having a plurality of weights for receiving a sequence of signal inputs x.sub.t,x.sub.t+1, x.sub.t+2 . . . , each input x.sub.t comprising n signal components x.sub.1 (t), x.sub.2 (t-1), . . . , x.sub.n (t-(n-1)) and for generating an output signal that anticipates the behavior of said input signal for a number of time samples ahead, said neural network comprising:transformation means for transforming a set of n signal inputs into a set of principal components having a saliency assigned to each of said princip...
