are called neurons. The thicker and darker the neuron is between nodes, the strong the affinity
between the nodes. The graph begins on the left, with one node for each predictor attribute.
These can be clicked on to reveal the attribute name that each left-hand node represents. The
hidden layer performs the comparison between all attributes, and the column of nodes on the right
represent the four possible values in our predicted (label) attribute: Role_Player, Contributor,
Franchise Player, or Superstar.

and the four nodes for each of the possible Team_Value categories.
Switch to the ExampleSet tab in results perspective. Again, as with past predictive models, we can
see that four new special attributes have been generated by RapidMiner. Each of our 59 athlete
prospects have a prediction as to their Team_Value category, with accompanying confidence
percentages.
