Frequency Domain
Frequency domain refers to the representation of a signal or data set in terms of its frequency components. In data science, frequency domain analysis is used to transform time-domain data into frequency-domain data using mathematical techniques such as Fourier transforms. This allows for the identification of patterns and trends in the data that may not be easily visible in the time domain. Frequency domain analysis is commonly used in signal processing, image processing, and audio processing applications. It is also used in machine learning for feature extraction and dimensionality reduction.
