WebJan 1, 1998 · GTM: The Generative Topographic Mapping. Abstract: Latent variable models represent the probability density of data in a space of several dimensions in terms of a smaller number of latent, or hidden, variables. A familiar example is factor analysis, which is based on a linear transformation between the latent space and the data space.
