Implementing Customer Segmentation using RFM analysis with ...

 · This article will go through a stepbystep approach to segment a customer base using the RFM model with the most popular distributed data processing framework, PySpark. In the future, we'll see how we can take advantage of Machine Learning algorithms (such as KMeans) to improve the segmentation process and even try to predict customer churns.
