What is the Boltzmann machine?

The Boltzmann machine is a type of neural network that is intrinsically a feedback network and has been a long-lived learning system. It was intriguingly connected to the ideas from Hopfield networks, leading to developments in restricted Boltzmann machines and deep belief networks. Key aspects of the Boltzmann machine include its ability to learn through feedback mechanisms and its connection to physics Hamiltonians or energy functions, which reflect its computational and physical characteristics. It remains a useful framework for understanding learning systems in artificial intelligence 1 .
