About the Project

Project Goal:

The project aims to segment customers into groups based on their buying habits using a clustering algorithm.
Data:

The data source would be the store's customer purchase history. This data would likely include:
Customer ID
Product ID(s) purchased
Quantity purchased
Purchase date(s)
Transaction amount
Preprocessing:

The data might need cleaning and preprocessing before applying the clustering algorithm. This could involve handling missing values, converting categorical data (e.g., product categories) into numerical representations, and potentially scaling the data to ensure all features have a similar impact on the clustering process.
Clustering Algorithm:

A popular choice for customer segmentation is K-Means clustering. It groups data points (customers in this case) into a predefined number of clusters (k) based on their similarity. Similarity is often measured by distance in a multidimensional space, where each dimension represents a feature extracted from the purchase history (e.g., total amount spent, frequency of purchase, product category preference).
Feature Engineering:

To improve the effectiveness of the clustering, additional features might be derived from the purchase history. Here are some examples:
Average purchase amount
Most frequently purchased product categories
Time between purchases (recency)
Total spent per category
Choosing the number of clusters (k):

Determining the optimal number of customer segments (k) is crucial. Techniques like the elbow method or silhouette analysis can be used to evaluate different k values and choose the one that yields the most distinct and meaningful clusters.
Interpretation and Action:

Once the clustering is complete, each customer will be assigned to a specific cluster. Analyzing the characteristics of each cluster (e.g., average purchase amount, preferred product categories) helps understand different customer segments. This information can be used for various marketing and sales strategies:
Targeted promotions and discounts based on customer segment
Personalized product recommendations
Loyalty programs tailored to specific customer needs
Benefits:

Customer segmentation through clustering allows retailers to better understand their customer base and tailor their marketing efforts more effectively, potentially leading to increased sales and customer satisfaction.
