Introduction to machine learning: Chapter 17 Boltzmann Boltzmann machine

Boltzmann Boltzmann machine Based on the idea of simulated annealing, Hinton and Ackley introduced random mechanism into Hopfield model and proposed Boltzmann machine. Like Hopfield model, the idea of Boltzmann machine is also the idea of energy. Hopfield model is a definite mechanism when calculating the state transition. Boltzmann machine i ...
