Simple artificial neural networks using multilayer perceptron
A very very brief introduction to neural network for physicists
Boltzmann machine is much like a spin glass model in physics. In short words, Boltzmann machine is a machine that has nodes that can take values, and the nodes are connected through some weight. It is just like any other neual nets but with complications and theoretical implications.
Artificial Neural Networks
Energy-based model like Boltzmann machine is a special type of neural networks
