Hertz
Hertz is a unit of frequency that measures the number of cycles per second of a periodic signal. In data science, Hertz is commonly used to refer to the frequency of a wave in a dataset. The frequency of a wave can be used to extract important features from the data, such as identifying patterns or anomalies. Hertz is also used in machine learning algorithms that involve signal processing, such as Fourier transforms and wavelet transforms. These algorithms use Hertz to convert time-domain signals into frequency-domain signals, which can then be analyzed and processed. Additionally, Hertz is used in the field of deep learning to specify the frequency of the input data, such as the frequency of an audio signal in a speech recognition system.
