Challenge: Segment Customers Using KMeans
Automated clustering is a powerful technique for uncovering hidden patterns and natural groupings within customer data that might not be immediately obvious. By leveraging algorithms like KMeans, you can segment customers based on their demographic and behavioral attributes, allowing you to tailor marketing strategies to each group more effectively. This approach helps you move beyond intuition and manual analysis, providing data-driven insights that can improve campaign targeting, product recommendations, and customer engagement. When you cluster customers, you often discover segments with distinct characteristics—such as high-value shoppers, bargain seekers, or infrequent browsers—that can inform personalized marketing actions.

Given a DataFrame with customer demographic and behavioral data, your goal is to segment customers into three clusters using KMeans clustering. The function should return the original DataFrame with an additional cluster label for each customer, as well as a summary DataFrame showing the average values of each numeric feature for each cluster.
- Select only the numeric columns from the input DataFrame.
- Fit a KMeans model with three clusters to the numeric data.
- Assign each customer a cluster label and add it as a new column called
clusterin the DataFrame. - Group the DataFrame by the
clustercolumn and calculate the mean of each numeric feature for each segment. - Return both the labeled DataFrame and the summary DataFrame.
