C# Класс AForge.MachineLearning.BoltzmannExploration

Boltzmann distribution exploration policy.

The class implements exploration policy base on Boltzmann distribution. Acording to the policy, action a at state s is selected with the next probability:

exp( Q( s, a ) / t ) p( s, a ) = ----------------------------- SUM( exp( Q( s, b ) / t ) ) b

where Q(s, a) is action's a estimation (usefulness) at state s and t is Temperature.

BoltzmannExploration ( double temperature ) : System	Initializes a new instance of the BoltzmannExploration class.
ChooseAction ( double actionEstimates ) : int	Choose an action. The method chooses an action depending on the provided estimates. The estimates can be any sort of estimate, which values usefulness of the action (expected summary reward, discounted reward, etc).
