Learn::LearningAgent & | learningAgent |
LearningAgent logged by the LALogger. | |
Learning Agent logger class that will be called during LearningAgent executions.
The idea of this class' methods is close to the idea of a callback. Each time the learning process does something, a specific method could be called by the LearningAgent. The many possible implementations of these methods allows the user to log whatever he wants.
|
explicit |
Constructor defining a given output and setting start and checkpoint as now. Default output is cout.
The constructed LALogger will add itself automatically to the Loggers of the given LearningAgent.
[in] | la | The LearningAgent which will be logged by this LALogger. |
[in] | out | The output stream the logger will send elements to. |
|
protected |
Computes the duration from a given time to now.
[in] | begin | Time from which the durations will be computed |
