Discrete Fourier Transform

Discrete Fourier Transform (DFT) is an important technique in the science of speech and sound measurement. It provides the frequency information of the signal. This post will be devoted to introduce the use of DFT in data science.

Energy-based models associate a scalar energy to each configuration of the variables of interest. Low energy is more desirable. The probability distribution based on an energy function can be modeled as follows
