WebFurthermore, assume that both the z’s and the noise follow multivariate Gaussian distributions. zn ˘N(zn jm 0,S 0) xnjzn ˘N(Wzn +m,Y). Since both are Gaussian, their joint distribution will be Gaussian and the marginal distribu-tion over x will be Gaussian. Our goal is to explain the data in terms of latent variables z. In the Gaussian case ... WebA latent variable is a variable that is inferred using models from observed data. For example, in psychology, the latent variable of generalized intelligence is inferred from …
