An Effective Conversation-Based Botnet Detection Method
Algorithm 2
Feature selection algorithm.
Input: train_data a labeled training set, test_data a labeled testing set | Output: PF a list of promising features | (1) an error range, the botnet traffic detection rate, | the current botnet traffic detection rate | (2) initialization , | (3) = Randonforest (all features) | (4) while do | (5) | (6) calculate RF scores of importance | (7) rank the RF scores | (8) delete the feature with the smallest importance from train_data and test_data | (9) = randomforest (remaining_features) | (10) end while |
