Well yes you’re exactly right. I’m planning to implement a one vs all method. I was under the impression it would not matter because if the model that classifies class 1 vs rest does not detect the image as class 1 it would pass it to the next model.
The 51% and 81% outputs means the following: the model was able to detect class 1 as class 1 81% of the time and class 0 (composed of the rest ie 0234) 51% of the time.
