Article Summary

The thickness of the branch line in the tree indicates how many samples traversed this path, meaning had these features. For example, the features along the blue line shown below had many samples as opposed to those along the purple line.

Hovering over a node in the tree displays information at the top-right corner of the page.

For example, hovering over the pink Age node (shown below), displays the Probability of 33.33% that Age>9.50 is False (0) and 66.67% that it is True (1). It also shows that 15 samples arrived at this node of the decision tree and that 5 of them are predicted as False (0) and 10 of them as True (1).

The Decision Rules area lists the decisions in the tree taken prior to the currently selected node.
