With orthonormal linear networks and optimized layer-wise projections, local-SSL updates equal global BP-SSL updates; adding top-down and 2D-spatial structure to CLAPP then nearly matches BP-SSL on CIFAR-10, STL-10, and Tiny ImageNet.

Can Local Learning Match Self-Supervised Backpropagation?
With orthonormal linear networks and optimized layer-wise projections, local-SSL updates equal global BP-SSL updates; adding top-down and 2D-spatial structure to CLAPP then nearly matches BP-SSL on CIFAR-10, STL-10, and Tiny ImageNet.
