You are faced with a multi-class classification problem. How would the choice of K and distance metric affect the KNN algorithm's ability to differentiate between the classes?
- Choice of K affects precision, distance metric affects generalization
- Choice of K affects recall, distance metric affects speed
- Choice of K and distance metric carefully affects differentiation between classes
- It has no effect
The careful selection of K and distance metric can greatly affect the KNN algorithm's ability to differentiate between classes in multi-class classification.
