Fast Fourier Transform (FFT) is an essential too for analyzing a signal's frequency content. One common operation before applying FFT is zero-padding, appending zeros to the end of a signal to increase the total number of samples used in the transform.
A fully connected neural network (FCNN), also known as a multilayer perceptron (MLP, 多层感知器), is a type of artificial neural network where every neuron in one layer is connected to every neuron in the subsequent layer.
