Class Activity: Decision Trees Objective: To solve a classification problem using a decision tree algorithm. Sample Dataset: Customer Turnover Customer Age Salary Tenure Turnover (Yes/No) 22 25000 2 No 35 40000 5 No 30 60000 10 No 45 50000 3 Yes 25 30000 1 Yes 50 70000 8 No 23 32000 1 Yes 40 45000 No 33 38000 6 Yes 29 52000 7 No 55 80000 38 48000 31 54000 42 62000 2913 No Yes 11 No Yes Tasks: 。 Identify the root node by calculating the information gain for each feature (Customer Age, Salary, Tenure). 。 Create the first split in the dataset. 。 Continue splitting the data to construct the full decision tree until all instances are classified.

For the following NFA M. 1 start 90 qi q2 From the list below, select all computations of M on the string 100. O go → go q1 → 92 92 qo → qo → q1 → q1 q0 → q0 → qi → q1 → q2
