WebImplicit layers and Deep Equilibrium models (DEQ) have recently been proposed as memory-efficient alternatives to super-deep networks. In this post we explore: the mathematical background behind implicit layers and gradients used by auto-differentiation systems; introduce deqx, a clean and flexible jax library including haiku implementations. lilyjack.com
