Clustering Users into Insightful Groups

Requirements Clarification & Assessment

To effectively approach the problem of clustering millions of users into insightful groups, it is crucial to first clarify and assess the requirements:

1. Objective Clarification:

   • Understand the primary goal of the clustering exercise. Is it to enhance marketing strategies, improve product recommendations, or gain insights into user behavior?
   • Determine the specific insights or outcomes expected from the clustering.

2. Data Understanding:

   • Gain a comprehensive understanding of the dataset, including user demographics, transaction details, product categories, and any other relevant information.
   • Assess the quality, completeness, and consistency of the data to identify potential preprocessing needs.

3. Scalability and Performance:

   • Evaluate the computational resources available and the scalability requirements, given the large volume of users and transactions.
   • Consider the need for real-time clustering or periodic batch processing.

4. Constraints and Limitations:

   • Identify any constraints related to data privacy, storage, or processing capabilities.
   • Consider limitations in terms of available algorithms or tools that can handle large-scale data efficiently.

5. Evaluation Metrics:

   • Define the metrics to evaluate the effectiveness and quality of the clustering, such as silhouette score, Davies-Bouldin index, or domain-specific metrics.

6. Stakeholder Alignment:

   • Engage with stakeholders to ensure alignment on objectives, expectations, and deliverables.
