SpletHowever, the authors consider a binary classification problem (normal vs. attack) which weakens the determination of causational factors. Moreover, as the dataset was shuffled and randomly divided into training and test data, ... (PCA) with Bayesian selection of the number of prin-ciple components is considered for dimensionality reduction SpletThe ultimate goal here is to perform classification on this data set. To this end, the professor mentioned to try PCA on this, and then placing those features into a classifier. ... PCA makes no guarantees that the principal components make demarcation between different classes easier. This is because the principal axes computed are axes that ...
