Title: Shallow Learning In Materio.. Abstract: We introduce Shallow Learning In Materio (SLIM) as a resource-efficient method to realize  closed-loop higher-order perceptrons. Our SLIM method provides a rebuttal to the Minsky school's disputes with the Rosenblatt school about the efficacy of learning representations in shallow perceptrons. As a proof-of-concept, here we devise a physically-scalable realization of the parity function. Our findings are relevant to artificial intelligence engineers, as well as neuroscientists and biologists.
