GTM: The Generative Topographic Mapping


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. In this article, we introduce a form of nonlinear latent variable model called the generative topographic mapping, for which the parameters of the model can be determined using the expectation-maximization algorithm. GTM provides a principled alternative to the widely used self-organizing map (SOM) of Kohonen (1982) and overcomes most of the signicant limitations of the SOM. We demonstrate the performance of the GTM algorithm on a toy problem and on simulated data from ow diagnostics for a mul-tiphase oil pipeline.
