When your experiment is finished, you will be presented with the results, i.e. all output returned by the outermost operator. This can be performance statistics, a decision tree or anything else. YALE automatically selects the Results tab.
When your experiment was conducted successfully, the view automatically switches to the Results tab. As far as your experiment chain produces an output, this tab shows you a visualization or a text describing the output. Figure 12 shows a decision tree learned from the golf data set.
At any time you can stop or pause (and resume) the experiment using the appropriate buttons or menu items in the Experiment menu. In any case the operator currently being executed will finish its execution. Since this might take some time (e.g. if the current operator was a learner) this might lead to a delay for experiment termination. Please be patient.
If you want to observe your experiment closely, you can set breakpoints before and after every operator (via the operator context menu). In that case, each time a breakpoint is reached, intermediate results are presented similar to the dialog popping up at the end of the experiment. You have to change to the Results tab to view the intermediate results. While your experiment is running you can observe the progress on the Monitor tab. You can see a plot of the memory usage and the progress bar.
