WebThe passive-aggressive (PA) algorithm is a modiﬁcation of the perceptron algorithm that requires predictions, y^ðtÞ, to be made with high conﬁdence [26]. The degree of conﬁdence in a prediction is measured by the magnitude jwðtÞ>zðtÞj. To this end a hinge-loss function is deﬁned that penalises both wrong Web54.8K subscribers [ http://bit.ly/LeToR] The Passive Aggressive (PA) algorithm is perfect for classifying massive streams of data (e.g. Twitter).
