One of the video tutorials I'm working on is how to build and use a direct mail marketing model using a Decision Tree learner. Rapidminer can be used for small, medium, and larger marketers as a data discovery tool that helps them understand the buying habits of their customers, and where to target their efforts. A Decision Tree model helps segment your market and identify the "sweet spot" in your customer base.
Check back over the next two weeks for this video tutorial. I'll show you how to mine your data and start being a more effective marketer in under 10 minutes.
