Average gradient outer product as a mechanism for deep neural collapse
This assumes that DNNs are infinitely expressive and, thus, optimizes for the feature vectors in the last layer directly.

More specifically,for the output features ofthe penultimate layer, for each class the within-class features converge to their means, and the means of different classes exhibit a certain tight frame structure, which is also aligned withthelastlayer'sclassifier.
