Rule-Based Classification: Create rules to classify vehicles into different classes based on attributes like Make, Type, Fuel Efficiency, Horsepower, Num Seats, and Price. 2. Rule Interpretation: Interpret the created rules. Explain the conditions under which a vehicle is classified into a specific class. 3. Rule Modification: Modify one of the rules to observe how it affects the classification. Explain the impact of the modification. 4. Rule Confidence: Assign confidence levels to the rules. For example, how confident are you in classifying a vehicle as "Sport" based on the rules? 5. Rule Expansion: Add a new rule to your rule-based system. Explain how this new rule contributes to the classification decisions. 6. Rule Visualization: Visualize your rule-based system in a decision tree format. Each rule should correspond to a branch in the decision tree. 7. Rule Application: Apply your rule-based system to the following instance: 8. Make: Toyota, Type: Sedan, Fuel Efficiency: 28.0, Horsepower: 160, Num Seats: 5, Price: 27000 9. Rule Refinement: Refine one of the rules to make it more specific or general. Explain the reasoning behind the refinement. 10. Rule Generalization: Generalize one of the rules to make it more applicable to a broader set of vehicles. Explain the reasoning behind the generalization.
