– variational Bayesian inference is the math as thermodynamics.
– Bayesian ensembling is like path integrals.
– backprop can be derived through Lagrangian saddle point method.
– convergence in non-convex objectives is spontaneous symmetry breaking.
– ConvNet pooling is like renormalization group theory and MERA tensor networks.
– and then, ConvNets can be Lorentz-equivariant
