The first video (YouTube) gives us a good idea about the initial stages of mining data like to import training and prediction data, to add a classification learner and then to apply the model.

The second video shows you how to use a cross and simple validation operator to split your training data into two sets: training and validation data sets.

The third video shows you how to create a decision tree to help us find “sweet spots” in a particular market segment. This video tutorial uses the Rapidminer direct mail marketing data generator and a split validation operator to build the decision tree.

After going through these videos, we are sure you will now be able to ease your way into RapidMiner.
