I'm trying to graph the results of a binary classifier as a ROC curve (hit rate vs false alarm rate) using yard-plot. The problem is that the graph does not reflect my data.
The command I call is:
C:\Python26\Scripts\yard-plot.exe -o E:\images\classifiers\roc_curve.png E:\images\classifiers\ROCData.txt
The input data "ROCData.txt":
output GrayHistogramEqualization NoPreprocessing
-1 0.853186 0.822022
-1 0.430748 0.422438
-1 0.178670 0.065789
-1 0.016620 0.010388
-1 0.000693 0.000693
-1 0.000000 0.000000
+1 0.993750 0.998750
+1 0.941875 0.950625
+1 0.840625 0.874375
+1 0.748750 0.787500
+1 0.670000 0.663750
+1 0.647500 0.657500
Each column is tab separated.
The current output "roc_curve.png": https://i.stack.imgur.com/IUpzW.jpg
Anyone know what could be causing this? Thanks.
