Introducing PC-ALM, a local-learning alternative to backpropagation. Our method trains 1000-layer neural nets using only local dynamics, and without backprop. Blog: Standard deep learning relies on backpropagation. The brain, however, cannot implement backpropagation, at least not exactly. How can a physical system, such as the brain, solve multilayer credit... show more

So how effective is it?

1000 layers is the headline. the interesting bit is the dual variables: each layer becomes a local PI controller, so credit doesn't have to diffuse end-to-end. if that maps efficiently to neuromorphic hardware, backprop stops being the only scalable story

@hardmaru Is this good or bad?

the local-dynamics story only pays off once neuromorphic hardware ships at volume, until then this is training an alternative to backprop for compute that barely exists outside a few research chips
