The finite-temperature free energy of the spherical perceptron with bounded continuous potentials (Gyorgyi-Reimann continuous-RSB formula)
Theorem 1.1: for all α,β>0 and ϕ∈Cb(R), EpN and pN (in probability) converge to infm{αVβϕ(m)+S(m)} over nondecreasing m:[0,1]→[0,1], with V a Brownian stochastic-control value and S the spherical entropy; this matches the Gyorgyi-Reimann continuous-RSB functional. Companions: the analogous formula for the Gaussian Ising perceptron with any bounded Borel log-potential at all densities and positive temperatures, and for spherical models with bi-orthogonally invariant disorder without outliers. Not shown: hard constraints or zero temperature (storage capacity), discontinuous potentials in the spherical case, or properties of the optimizer.
