In this project, we embarked on a comprehensive journey of exploring the dataset and conducting analysis and predictions in the context of online retail. We began by examining the dataset and performing RFM (Recency, Frequency, Monetary Value) analysis, which allowed us to gain valuable insights into customer purchase behavior. Using the RFM analysis results, we applied K-means clustering, a popular unsupervised Machine Learning algorithm, to group customers into distinct clusters based on their RFM values. This clustering approach helped us identify different customer segments within the online retail dataset. In order to provide a user-friendly and interactive experience, we developed a graphical user interface (GUI) using PyQt. The GUI allowed users to input customer information and obtain real-time predictions of the customer clusters using the trained machine learning models. This made it convenient for users to explore and analyze the clustering results. The GUI incorporated visualizations such as decision boundaries, which provided a clear representation of how the clusters were separated based on the RFM features.
