No, I am not saying it is better than CNN, but my images aren't real-life
images but computer generated silhouettes. So CNN seemed to be overkill.
I'll revisit CNN. I resized the images and converted it to grayscale. Now I
am feeding [1,4800] now and I am getting good output with MLP. I looped
over all my images and used partial_fit to train each one.
I didn't get what you meant by MLPClassifier doesn't support multi-output.
Thanks for the help!
