2. My First Model

KBL: My First Classification Model
Workflow: My First Model This workflow reads the data sets written by the Prepare Data workflow. It then trains two machine learning algorithms:- Naive Bayes- Decision Tree (C4.5)to predict Income (>50k / <=50K) based on the remaining input features.Finally, it scores both models on the test set.The last section is about visualization: ROC Curves and decision tree visualization.
