Boltzmann Machines

• One commonly used neural model (for machine learning) is the Boltzmann machine.
• They're basically LIF neurons.
• However, the firing threshold has some randomness included.
• You can model it by adding a random number to the threshold or voltage.
• So, a neuron will fire in some circumstances, and not fire in other identical circumstances.
• This randomness can be included in other neural models.
• It's commonly used for machine learning, but doesn't seem very common in computational neural modelling.
