Equilibrium Propagation
A reimplementation of Equilibrium Propagation: Bridging the Gap Between Energy-Based Models and Backpropagation. One version uses automatic differentiation with PyTorch, the other doesn't (still uses PyTorch though). There is a graph version as well (i.e. no tensors), but it is much slower.
Soon to be added: Generalization of Equilibrium Propagation to Vector Field Dynamics.
