Kernel principal component analysis (kernel PCA) [1] is an extension of principal component analysis (PCA) using techniques of kernel methods. Using a kernel, the originally linear operations of PCA are done in a reproducing kernel Hilbert space with a non-linear mapping.

This code is about OLA (overlap Addition method) of Digital Signal. First signal is converted into STFT and after that is recovered back to time domain signal using overlap Addition tecnique
