This section was of the tutorial was inspired fromWill Koehrsen’sHow to Visualize a Decision Tree from the random forest algorithm in Python using Scikit-Learn. Image byMichael Galarnyk. A weakness of decision trees is that they don’t tend to have the best predictive accuracy. This is par...

We used Weka v3.9, StarSpace [26], and Python code with implementations from the Scikit-learn, Keras, and Tensorflow libraries for the classification experiments. The classifiers we employed in Weka were Naïve Bayes, decision tree (J48/C4.5-based decision tree algorithm, Logistic regression (Mu...
