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."
