Inheritance diagram for classias::candidate_data_base< instance_tmpl, feature_generator_tmpl >:
This class represents a data set for training a candidate classifier. The class stores instances into a vector. This class implements the necessary functions num_attributes(), num_features(), and num_labels() for training algorithms. Do not forget to call set_num_features() to specify the total number of features.
