Challenge Problems
Push your limits with advanced challenges
You have a dataset with three overlapping classes. Write a Python function to visualize the decision boundaries for a KNN classifier. Include how you would explain the decision boundaries to a novice.
💡 Hint: Consider using np.meshgrid for creating your grid in the feature space.
You notice that some predictions are failing. Describe what you could change in your classifier or dataset to address the overlapping classes and improve decision boundary execution.
💡 Hint: Explore the impact of dimensionality or alternate classifiers.
