WebNoise is a term first applied to digital and analog systems in signal processing. To understand what noise in machine learning is, we first need to understand this original meaning. In signal processing, noise refers to unwanted modifications introduced to a source signal during the capture, storage, transmission, or processing of its information. WebSignal-to-noise ratio is an important and widely used metric for determining the confidence with which one can quantify a signal of a given value, especially a signal near background. The confidence in quantifying the signal increases as the variation in background signal (the ‘noise’) decreases, regardless of the absolute value of the mean background.
