List of all members.

Public Attributes
double	chisq
	Chi-Squared Error of Classifier evaluated on training set. Lower is better.
int	pos_rejects
	Number of positive examples rejected by classifier -- lower is better.
int	neg_rejects
	Number of negative examples rejected by classifier -- higher is better.
int	total_pos
	Total size of positive example pool.
int	total_neg
	Total size of negative example pool.
int	prev_pos_rejects
	Number of positive examples rejected by the classifier before, i.e. independent of the feature under consideration.
int	prev_neg_rejects
	Number of negative examples rejected by the classifier before, i.e. independent of the feature under consideration.
double	time_per_patch
	Time required to evaluate a patch with this feature. Lower is better.
double	threshold
	Rejection criterion used to generate these performance results.
