WebbRelevance vector machine. In mathematics, a Relevance Vector Machine (RVM) is a machine learning technique that uses Bayesian inference to obtain parsimonious solutions for regression and probabilistic classification. [1] The RVM has an identical functional form to the support vector machine, but provides probabilistic classification. WebbBoltzmann Machines are bidirectionally connected networks of stochastic processing units, i.e. units that carry out randomly determined processes. A Boltzmann Machine can be used to learn important aspects of an unknown probability distribution based on samples from the distribution. chesham vaccination centre
