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.roneverhart.com/Oakley-SI-Holbrook-Multicam-Men-s-Lifestyle-Polarized-Sunglasses-Brand-New/
