Member Typedef Documentation

EpsilonBase

using AIToolbox::Factored::Bandit::EpsilonPolicy::EpsilonBase = EpsilonPolicyInterface<void, void, Action>

Constructor & Destructor Documentation

EpsilonPolicy()

AIToolbox::Factored::Bandit::EpsilonPolicy::EpsilonPolicy	(	const PolicyInterface &	p,
		double	epsilon = 0.1
	)

Basic constructor.

This constructor saves the input policy and the epsilon parameter for later use.

The epsilon parameter must be >= 0.0 and <= 1.0, otherwise the constructor will throw an std::invalid_argument.

Parameters

p	The policy that is being extended.
epsilon	The parameter that controls the amount of exploration.

sampleRandomAction()

virtual Action AIToolbox::Factored::Bandit::EpsilonPolicy::sampleRandomAction ( ) const

overrideprotectedvirtual

This function returns a random action in the Action space.

Returns

A valid random action.

Implements AIToolbox::EpsilonPolicyInterface< void, void, Action >.
