Concepts from cryptography can be applied to speeding up algorithmsImago/AlamyAdding a dash of encryption to key algorithms used in artificial intelligence models could surprisingly make them more efficient, thanks to a trick of mathematics.Cryptography normally involves scrambling messages to make them appear random to malicious onlookers while preserving their information by hiding a pattern in the randomness. This randomness can then be unlocked with the correct key.Now, Or Zamir at Tel Aviv University in Israel and Vinod Vaikuntanathan at the Massachusetts Institute of
