Hello Mahesan,
Thank you for pointing that out. This was actually before the latest built,
This was happening because of following code snippent in view-model.jag
var actual = testResultDataPointsSample[i].predictedVsActual.actual;
var predicted =
testResultDataPointsSample[i].predictedVsActual.predicted;
var labeledPredicted = labelPredicted(predicted, 0.5);
if(actual == labeledPredicted) {
predictedVsActualPoint[2] = 'Correct';
}
else {
predictedVsActualPoint[2] = 'Incorrect';
}
where it should compare *actual == predicted* for deeplearning. But it is
fixed in the latest commit as CD mentioned.
So it is working properly at the moment.
I've attached a screenshot of new version
