From: Detecting unknown malicious code by applying classification techniques on OpCode patterns
The mean TPR, FPR, accuracy and G-Mean for each classifier (using TF representation) as a function of the OpCode n -gram size. The performance of both the Naïve Bayes and the Boosted Naïve Bayes was worst for all n-gram sizes having the lowest mean TPR, accuracy and G-Mean and highest mean FPR. The mean accuracy, TPR and G-Mean of the 2-gram outperforms all the other n-grams with the lowest mean FPR for all classifiers.
