5 years ago Percent_Selected is the percentage of tiles where the probability is the highest. 0 means that for this given slide, no tile has its max prob assigned to class 2.
Not sure I understand your second question. out_filename_stats shows the prob. assigned to each tile as calculated by inception.
We took 250 SVS images from TCGA. We used a 3Class classifier for training for 50000 steps, validating. The loss reached to 1.4.
After the testing, when I run script for ROC curves, I got a file named out2_perSlideStats.txt in output folder in which lines looks like this :

Percent_Selected for LUAD always remained 0 except for one(second) slide. What does Percent_Selected actually convey and is it correct to get an output like this? How is the final prediction calculated for a slide and which program calculates it?
