Abstract :
We prove that perceptrons separating Boolean matrices in which each row has a one from matrices in which many rows have no one must have either large total weight or large order. This result extends one-in-a-box theorem by Minsky and Papert (1988) stating that perceptrons of small order cannot decide if each row of a given Boolean matrix has a one. As a consequence, we prove that AM∩co-AM⊄≠PP under some oracle. This contrasts the fact that MA⊆PP under any oracle
