This presentation explores the mathematical design principles of biological neural circuits -- building upon the classic concept that neural activity is fundamentally driven by cost minimization and energy landscapes.<br><br>We demonstrate a direct mathematical equivalence between the firing dynamics of recurrent neural networks and "proximal gradient descent, "a novel dynamical system used to solve optimization problems. This framework provides a top-down explanation for how biological networks process information, illustrated through examples such as sparse signal reconstruction in the visual cortex and decision-making via the free energy principle. Finally, we extend these concepts to complex excitatory-inhibitory circuits, modeling neurons as players in a mathematical game. We conclude by briefly discussing how these biological insights can inspire next-generation analog and neuromorphic computing.<br><br></div><div><br></div><div>Bio:</div><div>Francesco Bullo is a Distinguished Professor and Mosher Chair of Mechanical Engineering at the University of California, Santa Barbara.
