Member Function Documentation

choose()

template<typename T>

T Brush::MAB::DummyBandit< T >::choose ( const VectorXf & context )

virtual

Chooses an arm based on the given tree and fitness. Should call sample_probs internally.

Parameters

tree	The tree structure used to choose the arm.
f	The fitness value used to influence the choice.

Returns

The arm with highest probability.

Reimplemented from Brush::MAB::BanditOperator< T >.

sample_probs()

template<typename T>

std::map< T, float > Brush::MAB::DummyBandit< T >::sample_probs ( bool update )

virtual

Samples the probabilities of the arms.

Parameters

update

A boolean indicating whether to update the probabilities.

Returns

A map of arms and their probabilities.

Reimplemented from Brush::MAB::BanditOperator< T >.

update()

template<typename T>

void Brush::MAB::DummyBandit< T >::update ( T arm, float reward, VectorXf & context )

virtual

Updates the reward for a specific arm.

Parameters

arm	The arm for which to update the reward.
reward	The reward value.
