Comprehensive Retail Market Analysis: Clustering and Association Rule Learning
This project combines unsupervised learning techniques with Association Rule Learning to analyze retail market basket data. By applying clustering algorithms (K-Means and DBSCAN) and association rule mining algorithms (Apriori, Eclat, and FP-Growth), the project aims to uncover customer purchasing patterns and segment customers into meaningful clusters. The goal is to provide actionable insights for optimizing product placement, promotional strategies, and product development.

Data Loading and Preprocessing:
- Import Data: Load transaction data from a CSV file (
groceries.csv
) containing customer purchase records. - Data Transformation: Convert transaction data into a binary matrix using the
TransactionEncoder
from themlxtend
library. This transformation prepares the data for Association Rule Learning.
- Import Data: Load transaction data from a CSV file (

Frequent Itemset Mining with Association Rule Learning:
- Apriori Algorithm: Apply the Apriori algorithm to identify frequent itemsets with a minimum support threshold of 0.05. Use Breadth-First Search to iteratively find itemsets and generate association rules.
- Eclat Algorithm: Utilize the Eclat algorithm to find frequent itemsets through Depth-First Search, offering a comparison in terms of performance with Apriori.
- FP-Growth Algorithm: Implement the FP-Growth algorithm to discover frequent itemsets using a Frequent Pattern Tree (FP-tree), avoiding candidate generation and improving efficiency.
-
Clustering Analysis:
- K-Means Clustering: Apply K-Means clustering to segment customers based on their purchasing behavior. Determine the optimal number of clusters and analyze the clusters to understand customer segments.
- DBSCAN Clustering: Use DBSCAN (Density-Based Spatial Clustering of Applications with Noise) to identify clusters of varying shapes and densities. Evaluate how this algorithm complements K-Means by identifying noise and outliers.
-
Association Rule Generation:
- Generate Rules: Extract association rules from frequent itemsets identified by the Apriori, Eclat, and FP-Growth algorithms. Assess the rules using metrics such as support, confidence, and lift to identify actionable patterns.
-
Data Visualization and Interpretation:
- Visualize Clusters: Create visualizations to represent the clusters formed by K-Means and DBSCAN. Use scatter plots and cluster heatmaps to illustrate the customer segments and their purchasing patterns.
- Visualize Association Rules: Generate visualizations to display frequent itemsets and association rules. Use bar charts and heatmaps to represent the strength of item associations and support values.
-
Practical Applications and Recommendations:
- Retail Strategies: Recommend strategies for optimizing store layouts and product placement based on cluster analysis and association rules. For example, group related items and place them together to enhance cross-selling opportunities.
- Promotional Campaigns: Suggest targeted promotional campaigns based on customer segments and frequent itemsets. Design offers or discounts that cater to specific customer clusters and their purchasing habits.
- Product Innovation: Explore opportunities for creating new product bundles or combinations based on frequent itemsets and cluster profiles.
- Pandas: For data manipulation and preprocessing.
- Matplotlib and Seaborn: For data visualization.
- mlxtend: For implementing Association Rule Learning algorithms.
- Scikit-Learn: For K-Means and DBSCAN clustering algorithms.
This comprehensive project description now includes both clustering and association rule learning, providing a clear overview of the techniques used and their applications in retail market analysis.
