i am using some algorithms from weka . i was willing to plot some algorithms' roc curve for comparison . Is it possible and how ?
- In the Weka explorer, go to the classify tab and train/test your algorithm.
- The result buffer appears in the bottom left box under the section labeled "result list"
- Right click the result buffer and click visualize threshold curve, then select the class you want to analyze
- to save the ROC curve as an image, hold shift + alt and left click on the graph
