I'm using cross validation with LibSVM algorithm and i wonder if i can visualize via rapid miner the Precision-Recall Space and ROC Space graphs in order to compare my results. Is there any method to visualize the graphs?
you can visualize the ROC plot if you use the Performance operator, or if you use the Performance (Binominal Classification) operator and select the AUC measure. In the results view, just display the AUC, and you will get a nice ROC chart.
