Main constructor of the ClassificationLearningEnvironment.
[in] | nbClass | number of classes of the classificationLearningEnvironment, and thus number of action of the underlying LearningEnvironment. |

overridepure virtual |
Default implementation for the doAction method.
This implementation only increments the classificationTable based on the currentClass attribute. Refresh of the data should be implemented by the child class, hence the pure virtual method.

overridevirtual |
Default scoring for classificationLearningEnvironment.
The default scoring for the classificationLearningEnvironment is computed based on the classificationTable attribute.
The score represents the percentage of correct classification.
Implements Learn::LearningEnvironment.
|
overridepure virtual |
Default implementation of the reset.
Resets to zero the classificationTable.
Implements Learn::LearningEnvironment.
|
protected |
2D array storing for each class the guesses that were made by the LearningAgent.
For example classificationTable.at(x).at(y) represents the number of times a LearningAgent guessed class y, for a data from class x since the last reset.
|
protected |
Class of the current data.
This attribute should be updated alongside the data made avalaible to the LearningAgent.
