This article delves into the mathematical underpinnings of reward systems in AI, exploring how proper scoring rules can be directly linked to information measures. It demonstrates that every convex function can generate a unique information theory, defining generalized entropies and cross-entropies. The piece further connects these concepts to mirror ascent, a gradient ascent method that optimizes for the steepest increase in an objective function within a constrained step size. AI
