Before revision:  In this paper, we take a major step in addressing this challenge and present a new  framework, called PRIMA , that computes precise convex approximations of arbitrary non-linear activations.
After revision:  In this paper, we take a major step in addressing this challenge and present a new framework, called PRIMA . PRIMA is both (i) general: it handles any non-linear activation function, and (ii) precise: it computes precise convex approximations of arbitrary non-linear activations.
