PBC Tour (2/4)

First Steps

Please select the node of the decision tree (the "? to be processed.." line) with a left-click on that line. Now the node is marked. Now right-click on the same line to invoke a context-sensitive popup-menu. All the classes present in this node are listed with the associated color and their absolute frequency. In the popup menu you may select actions concerning this (root) node. Either the tree can be automatically expanded from this node downwards or this node can be converted into a leaf by selecting one of the classes.

Please click on the "expand tree" option to let the system automatically compute the whole decision tree. Then you may expand the branch nodes by clicking the circle to the left of an expanded node. Now you may left-click on any node. A left-click marks this node as an active node and invokes a visualization of that node in the main panel. The splitting decision is also shown.
