Boltzmann learning
WebBoltzmann machines are unsupervised, energy-based probabilistic models (or generators). This means that they associate an energy for each configuration of the variables that one wants to model. Intuitively, learning in these models corresponds to associating more likely configurations to lower energy states. In these states there are units that ...

Did you know?
WebBoltzmann machines operate in two modes: clamped, in which visible neurons are clamped onto particular states determined by the environment; and free-running, in which both visible and hidden neurons are allowed to operate freely. Boltzmann learning is a stochastic learning rule derived from information-theoretic and thermodynamic principles. WebThe Restricted Boltzmann machine (RBM) is a classic example of building blocks of deep probabilistic models that are used for deep learning.The RBM itself is not a deep model but can be used as a building block to form other deep models. In fact, RBMs are undirected probabilistic graphical models that consist of a layer of observed variables and a single …
