| Abstract(in English) | A method for measuring similarity between two random variables is presented. Our approach considers the case where available observations are arbitrarily filtered versions of original variables. In this paper, we propose an error-minimizing filter (EMF) which minimizes an error between outputs, and the error is utilized for the similarity. The EMF is constructed by a finite impulse response (FIR) filter, and the error between the outputs is evaluated by the mean square error (MSE). We show that minimization of the MSE results in an eigenvalue problem, and the optimal solution is given in a closed form. We also propose an application of the EMF to the blind signal separation (BSS) problem. |
