Evaluation of Machine Learning Algorithms for Intrusion Detection System

To gauge the accuracy of machine learning models we use various parameters. The metrics used here will be Average Accuracy, False Positive Rates and False Negative Rates. K-Means is excluded from this metric as it is an unsupervised algorithm. Average Accuracy is defined as the ratio of the correctly classified data points to the total number of data points. False Positives are those cases which were supposed to be returned as threats but aren't. False negatives are just the opposite.
