intermediate Published 5 Apr 2026
Action Steps
  1. Collect and preprocess 3 years of customer purchase data, including timestamps and category information
  2. Apply time-series clustering algorithms, such as Dynamic Time Warping or Longest Common Subsequence, to identify patterns in customer behavior
  3. Use dimensionality reduction techniques, such as PCA or t-SNE, to visualize high-dimensional customer data
  4. Evaluate cluster quality using metrics such as silhouette score or Calinski-Harabasz index
  5. Refine clustering model by experimenting with different algorithms, parameters, and feature engineering techniques
