The notebook presents a detailed customer segmentation analysis, possibly designed for a financial services firm, such as XYZ Life Insurance. Below is an outline of the key sections and tasks covered in the analysis:
- Overview & Objective:
- The primary aim is to segment customers to enable the delivery of targeted services, including savings plans, loans, and wealth management.
- Data Handling:
- The analysis is conducted using data from credit_card_dataset.csv. Initial data handling includes basic cleaning steps such as addressing missing values and removing unnecessary columns.
- Exploratory Data Analysis (EDA):
- Summary statistics, null value checks, and outlier detection are performed.
- Visualizations are likely used to understand the distribution of key features.
- Feature Scaling:
- Standardization of features is performed using StandardScaler to ensure that the data is appropriately scaled for clustering.
- Clustering with K-Means:
- The K-Means algorithm is applied to segment the customers into distinct clusters.
- A new cluster column is created in the dataset to store the cluster labels assigned to each customer.
- Cluster Analysis:
- Each cluster is analyzed in detail, representing different customer types: For example, "Transactors" are identified as customers who pay minimal interest charges and are likely careful spenders.
- The analysis delves into the characteristics of customers within each cluster.
- Model Saving:
- The K-Means model is saved for future use, and the dataset with the assigned clusters is exported as Clustered_Customer_Data.csv.
The analysis in the notebook segmented customers into four distinct clusters using the K-Means clustering algorithm. Each cluster represents a group of customers with similar behavior and financial characteristics, which can be used for targeted marketing and service offerings. Here's a brief overview of the clusters:
Cluster 1: Transactors Characteristics: These customers generally have low balances and make frequent, small purchases. They are careful spenders who tend to pay off their balances regularly, leading to minimal interest charges. Implications: These customers might be targeted with offers that reward frequent transactions, such as cashback on purchases.
Cluster 2: Revolvers Characteristics: Customers in this cluster carry higher balances and often revolve credit, meaning they do not pay off their balances in full each month. They may have higher interest charges and a tendency to use credit more extensively. Implications: This group could be targeted with offers for balance transfers or interest rate reduction plans to retain their loyalty.
Cluster 3: Silver Segment Characteristics: These customers are somewhere between Transactors and Revolvers. They make significant purchases but may also carry a balance. They are likely moderate users of credit, balancing between spending and repayment. Implications: Products like low-interest loans or credit line increases might appeal to this segment.
Cluster 4: Big Spenders Characteristics: This group has the highest balances and spending levels. They may make large purchases and use credit heavily. They might also have higher credit limits and more financial activity overall. Implications: Premium services, such as wealth management or high-end credit cards with exclusive benefits, might be most appealing to this group.
Conclusion: The segmentation identifies key customer groups, enabling targeted strategies that align with each group's financial behavior. This approach helps in tailoring marketing efforts and financial products to meet the specific needs of different customer segments, enhancing customer satisfaction and profitability.
