How I fixed over 50 label issues in a popular semantic segmentation dataset

Hi folks! I've made a new technique for finding errors in semantic segmentation datasets, using new explainable AI techniques from my PhD. I was frankly pretty surprised to be able to find over 50 different error patterns , and 7% of total pixels labelled incorrectly, in MIT ADE20K (one of the most widely used segmentation datasets).
