Exercise3

<p><strong>Chapter 4/Exercise 3</strong></p><p>This workflow is another exerciser for classification training a Naive Bayes Learner model using data of the <em>website1.txt</em> file.</p><p>First, it's calculating basic stats of the number of visitors ("no visitors"). Then, after some preprocessing, it's training a Naive Bayes model (<em>Naive Bayer Learner</em> node) to classify "weekend" vs. "no weekend" according to the number of visitors of a website. Lastly, it's evaluating the model by calculating a confusion matrix (<em>Scorer </em>node) and visualizing the area under the curve (AuC) (<em>ROC Curve</em> node).<br></p>
