I have heard from my professor that a current research article about classifying images of horse breeds by means of CNN got debunked. The reason was that the input image data had their corresponding labels on the images themselves so the classifier learned to achieve it’s high accuracy looking at the correct labels instead of the actual horses. Apparently nobody bothered to have a closer look on the input files. Unfortunately, I cannot find the article or related ones online. Would anybody else know where to find it? Thanks in advance!
