Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You are given a dataset with 2-dimensional data arranged in a circular pattern. Discuss how K-Means might struggle with such a dataset and propose alternative clustering methods.

💡 Hint: Think about the limitations of K-Means for various cluster shapes.

Challenge 2 Hard

Consider a dataset with significant outliers and a desired number of K as 3. Propose a preprocessing step to improve K-Means performance on this data.

💡 Hint: Think about preprocessing techniques that can handle skewed data.
