Does anyone know anything more about these “capsules”? I’ve seen some nature articles on them but these were from a neuroscience perspective. Has Hinton published anything on them? Also if Hinton is the Einstein of deep learning, then will capsules be his “unified field theory”? I feel that if we embrace the Einstein analogy we should embrace it to its fullest.
