The proposed method is called Z-score based NC, ZSNC. It observes the ratio of neurons that do not fall within an interval for a given class. The class-specific bounds for each neuron consists of mean and standard deviation of class-specific features in train set, which can be calculated iteratively and scaled by epsilon that is selected from z-score table. To fit the range with FD+, we select 1.96 as a scaling factor. The proposed method does not need to save all output values from training set.
