Predicting Customer Churn with Gradient Boosting

Posted by Salford Systems on Fri, May 6, 2016 @ 07:00 AM

Customer churn presents a particularly vexing problem for businesses; every company loses clients or customers over time. It's no wonder that companies are pouring money and time into this issue, we've all heard that it's less costly to retain a customer than to attract a new one.   Let's take the wireless telecommunications industry as an example. In 2003, the wireless telecom industry had 20-40% of customers leaving their provider in a given year. As once-explosive subscriber growth rates slowed down, retaining existing customers became increasingly important to a company's overall profitability. Currently, annual churn rates for telecommunications companies average between 10-67%. If the customers who are likely to churn can be identified, the company can target them with retention campaigns, giving them an incentive to stay and preventing loss of revenue.

Supercharging Predictive Modeling: A Beginners' Perspective

Posted by Heather Hinman on Fri, Apr 26, 2013 @ 06:05 AM

Salford Systems recently attended the Predictive Analytics World (PAW) conference in San Francisco as a sponsor. Manning the exhibit booth was yours truly, and I was fortunate to meet many analysts, predictive modelers, and data scientists of all experience levels. Even though this is always an entertaining break from every-day office life, my favorite part of the conference was being able to participate in a workshop offered by Dean Abbott, President of Abbott Analytics, entitled "Supercharging Prediction: Hands-On With Ensembles Models."
