How to select the appropriate threshold (conf_thresh) value?

[kmsravindra]

@AlexeyAB, Hi

I am using yolov3 and I want to select the best confidence threshold that maximizes F1 score. So to do this, will I have to run "darknet detector map -thresh 0.x" command multiple times for each value of x ranging from 0.1 to 0.9 and draw a plot, so that I can select an appropriate threshold value?

I want to select the threshold that gives good true positives while trading off some false positives / false negatives.

Any other better ways you can suggest to find this threshold ?

Thanks.
