Abstract

Given the high number of transactions, deposits, withdrawals, loans, cards, and other financial operations that a bank undertakes, it accumulates a significant amount of data about its customers. Information assets can be utilized in various ways, including analyzing the behavior of customers and understanding their financial needs. This paper aims to propose a data science approach for the segmenting of bank customers. It will undertake the task of exploring and preparing the data for analytical procedures. The study will attempt to engineer several features that can help identify segments with similar characteristics. The research will engage such methods as K-Means, Hierarchical Clustering, DBSCAN, and Gaussian Mixture Model to operationalize the task of customer segmentation. The paper will also try to incorporate a temporal component into the analysis. The proposed approach would allow banks to better comprehend the customer base and facilitate more precise marketing strategies.

Full Article/Conclusion

The Bank Customer Segmentation Using Data Science study can benefit the banks by providing them with the knowledge of how customers behave, what are their needs, and how they spend their money. The demographic and financial data of the customers can be analyzed and divided into segments based on specific criteria. The segments can be identified using the data science methods, such as K-Means, Hierarchical Clustering, DBSCAN, or Gaussian Mixture Models. The information gained from the analysis can be used to find the marketing strategies, which would be beneficial for the bank, its clients, and shareholders. Despite the potential usefulness of data science, there are some considerable threats and difficulties, including the privacy and accuracy concerns regarding the data and the complexity of choosing the right model for the analysis.
