Member Function Documentation

virtual vector<double> BALL::QSAR::BayesModel::calculateProbabilities	(	int	activitiy_index,
		int	feature_index,
		double	feature_value
	)			[pure virtual]

calculate the probability for the specified feature to assume the given value for each class

Returns:

a probability for each class

Implemented in BALL::QSAR::NBModel, and BALL::QSAR::SNBModel.

virtual int BALL::QSAR::BayesModel::getNoResponseVariables

(

)

[pure virtual]

returns the number of response variables for which this model has been trained

Implemented in BALL::QSAR::NBModel, and BALL::QSAR::SNBModel.

virtual bool BALL::QSAR::BayesModel::isTrained

(

)

[pure virtual]

Implemented in BALL::QSAR::NBModel, and BALL::QSAR::SNBModel.

Member Data Documentation

double BALL::QSAR::BayesModel::min_prob_diff_ [protected]

the minimal desired difference between the predicted class and the second best class. If the difference is smaller than this value, undef_act_class_id_ should be used instead.

Definition at line 56 of file bayesModel.h.

double BALL::QSAR::BayesModel::undef_act_class_id_ [protected]

the class_id that is to be assigned, if no class could be savely predicted, if difference between best and second best potential class is smaller than min_prob_diff_
