Different of gaussian
WebThere are a huge number of harmonics in the railway power supply system. Accurately estimating the harmonic impedance of the system is the key to evaluating the harmonic emission level of the power supply system. A harmonic impedance estimation method is proposed in this paper, which takes the Gaussian mixture regression (GMR) as the main … In mathematics, a Gaussian function, often simply referred to as a Gaussian, is a function of the base form Gaussian functions are often used to represent the probability density function of a normally distributed random variable with expected value μ = b and variance σ = c . In this case, the Gaussian is of the form
