Lаb Wоrk: Use this dаtаset: credit_apprоval.csv This is a credit apprоval dataset whose columns are anonymized for reasons of security. The binary class variable is A16. It has two values: '+' and '-'. For your analysis, consider '+' to be the positive outcome. Add a note on your workflow with your full name and UID. Create an analytic workflow using the Tree widget and apply to the Base Model and a Comparative Model (include A16 in both models) - see the steps below. All the Tree widgets in this analytic experiment must have the following properties: Check (select) the box "Induce binary tree". Min. number of instances in leaves: 20 Do not split subsets smaller than: 30 Limit the maximal tree depth to: 5 Stop when majority reaches [%]: 95 Steps to create your analytic workflow: Use CSV File Import widget to import the credit_approval file. Use Select Columns on the main dataset and designate A16 as the target variable. Use Select Columns to create your Base Model with the following rule: If your UID ends in an even number, your Base Model columns are all the even-numbered columns. If your UID ends in an odd number, your Base Model columns are all the odd-numbered columns. Use Select Columns on the main dataset to create the Comparative Model columns that have the following columns: A6, A8, A9, A10, A11, A14, A15. Connect your Base Model and a Tree Widget to a Test and Score widget (use 5-fold cross validation). Connect the Test and Score widget to a Confusion Matrix widget. Connect your Comparative Model and a Tree Widget to a Test and Score widget (use 5-fold cross-validation). Connect the Test and Score widget to a Confusion Matrix widget. Calculate accuracy, recall, specificity, and precision for both the Base Model and the Comparative Model and record them in a table (as a note on the workflow) where the rows are for the models. Take screenshots of the full workflow in Orange DM, Properties panes of the following widgets: Select Columns, Tree, Test and Score, Confusion Matrix. You should have 10 screenshots: Full workflow (1), Select Columns (3), Tree (2), Test and Score (2), Confusion Matrix (2). Please rename the widgets to reflect Base or Comparative model. Paste into Powerpoint, arrange the screenshots neatly, save as PDF, and upload.
