I have to check that because I did not clean the dataset (other than automatically eliminating a subset of it). If that is the case, it did not get my attention while working on it. However there could be a subset of images where your suggestion could be true. Thanks.
Edit after checking;
@ptrblck The images in my dataset dont have a subset that have a special right side, exactly. However my dataset is comprised of special kind of images (logos or logotypes in general). Most of the images are symmetric or “almost” symmetric with small changes along the vertical axis. And most of the variation is on the left side (since most interesting figures of logos are on the left side or above of text by tradition as in “sunny escape” logo shown above). My network may be learning to cheat a little by smudging a low resolution version of the leftside to the right side. Whatever the reason is, I will come back here let you guys know, after I figure out a way to solve this problem. Other ideas are also
welcome.
