I took a very shallow look at the paper. Considering the proposed approach and methodology this would seem quite exciting. Although I am not in touch with the subject anymore but still retain the basics to get through the paper.

I remember my professor talking about "optimal combination of diverse learning algorithms" without any substantiating proof that the combination of this implementation is itself done by a higher algorithm. This was a couple of years ago.

Would love to get more info when the group publishes more
