PBC Tour (4/4)
Interactive Classification
You should be in "Normal mode" which is indicated by the cursor shaped
as an arrow. Based on the perception or on domain knowledge you may select
an attribute by left-clicking on a segment. Then an arbitrary number of
split points can be set within the segment by left-clicking the respective
positions. An animated line appears on the clicked position and the original
pixels of that line are redrawn in a magnified fashion at the bottom. There
the user may set the exact split point by moving the slider. After all
splits are set, right-click on the visualization of the data. A popup menu
opens and there you can select the last option ("split attribute"). As
a result, the split is performed and the decision tree on the right side
is updated.
Now you may select another node of the tree by clicking it. A visualization
of this node is invoked and you can proceed in the same way.
To switch to another visualization of the node (Bars, Circle Segments), select the menu Options-> Visualization.
