10 Supervised Methods

While with scaling we try to place our texts on a scale, with supervised methods we go back to what we did with dictionary analysis: classification. Within quanteda there are many different models for supervised methods, of which we will cover two. These are Support Vector Machines (SVM) and Naive Bayes (NB). The first classifies texts by looking at their position on a hyperplane, the second by their (Bayesian) probabilities.
