Description
This course guides you through applying machine learning and data science techniques to build a store segmentation from raw data in order to generate actionable, easy-to-understand segments for stakeholders. Based on a real-world project implemented in a retail company (with synthetic data due to confidentiality), the course follows key steps in the data science lifecycle.
Next, we dive into data cleaning, preprocessing, and feature engineering, followed by exploratory analysis using correlation matrices, distribution plots, and boxplots. We apply data transformations such as winsorization, Yeo-Johnson, and standardization before running a PCA to explore latent structure and guide the segmentation process.
For modeling, we focus on finding the most stable clustering solution, using Jaccard similarity to evaluate consistency across random states. We evaluate the optimal number of clusters with the Elbow method and assess quality of the clustering using Silhouette score.
To describe the resulting segments, we adapt a profiling technique inspired by SAS Miner. We use decision trees to identify the most distinguishing features per segment, then visualize distributions to compare each segment against the overall population. This allows us to craft simple, stakeholder-friendly descriptions based on key deviations.
Finally, we wrap everything up with a presentation of results, ready to support data-driven decision-making in a retail context.
