Advanced Predictive Modeling Using IBM SPSS Modeler

Overview

modeler3

This course builds on the courses Classifying Customers Using IBM SPSS Modeler and Predicting Continuous Targets Using IBM SPSS Modeler. It presents advanced techniques to predict categorical and continuous targets. Before reviewing the modeling techniques, data preparation issues are addressed such as partitioning and detecting anomalies. Also, a method to reduce the number of fields to a number of core fields, referred as components or factors, is presented. The next two modules focus on advanced predictive models, such as Decision List, Support Vector Machines and Bayes Net. Following this presentation, two modules present methods to combine individual models into a single model in order to improve predictive power, including running and evaluating many models in a single run, both for categorical and continuous targets.
