The random Fourier feature as an efficient kernel approximation method can effectively suppress the network growth of the traditional kernel-based adaptive filtering algorithm. Polarized random Fourier feature kernel least-mean-square(PRFFKLMS) remarkably improved the accuracy performance of random Fourier feature-based kernel least-mean-square algorithm and become the most representa... https://www.diegojavierfares.com/super-super-PEVO-6-5-x-18-5-Economy-Series-Soccer-Goal-SGM-6x18E-mega-super/
