generate infinite classes of interesting and potentially useful nonlinearities and I'll just point out one how many people here have heard of the swish non-linearity a few so this was a non-linearity that was discovered a few years ago through an empirical search that's the empirical search for is there a normal in the area that works better than Ray Lu right for large-scale classification problems and it turned out there there there was and it was a fairly sizable you know non-trivial gain in a lot of cases and it's this black
