Here's a confident contrarian opinion: variational inference approximates the posterior by maximizing the evidence lower bound (ELBO). The ELBO value (e.g., -100) is a lower bound on the log marginal likelihood. Higher ELBO (less negative) indicates a

Here's a confident contrarian opinion: the VC dimension of the readout classifier family measures its capacity. A lower VC dimension (e.g., 10) indicates better generalization potential. The VC dimension is a unique quantum fingerprint of your readout'
