Abstract
A multiclass classifier generates a probability vector for individual data units of an input data stream. The probability vector has prediction probability values for classes that the multiclass classifier has been trained to detect. A class with the highest prediction probability value among the classes in a probability vector is selected as the predicted class. A confidence score is calculated based on the prediction probability value of the class. Confidence scores of the class are accumulated within a sliding window. The class is declared to be the detected class of the input data stream when the accumulated value of the class meets an accumulator threshold. A security policy for an application program that is mapped to the class is enforced against the input data stream.
