Abstract
A kernel adaptive algorithm enables to learn a nonlinear system by applying kernel method. However, increasing the number of training vectors while estimation processes causes a huge computational cost. This paper proposes a sparsification of proportionate-type of KNLMS, which updates filter coefficients with the individual step size, in the case that the size of the dictionary is limited.
