The classical result of concentration of the Gaussian measure on the sphere in the limit of large dimension induces a natural duality between Gaussian and spherical models of spin glass. We analyse the Legendre variational structure linking the free energies of these two systems, in the spirit of the equivalence of ensembles of statistical mechanics. Our analysis, combined with the previous work (Barra et al., J. Phys. A: Math. Theor. 47, 155002, 2014), shows that such models are replica… Expand
Legendre equivalences of spherical Boltzmann machines
TLDR
The free energies of the spherical and Gaussian models are related by a Legendre transformation and this analysis brings also a new purely variational derivation of the free energy of theherical models. Expand

Large time zero temperature dynamics of the spherical p=2-spin glass model of finite size
We revisit the long time dynamics of the spherical fully connected $p = 2$-spin glass model when the number of spins $N$ is large but {\it finite}. At $T=0$ where the system is in a (trivial)Expand

Phase Diagram of Restricted Boltzmann Machines and Generalised Hopfield Networks with Arbitrary Priors
TLDR
This analysis shows that the presence of a retrieval phase is robust and not peculiar to the standard Hopfield model with Boolean patterns, and the retrieval region becomes larger when the pattern entries and retrieval units get more peaked and, conversely, when the hidden units acquire a broader prior and therefore have a stronger response to high fields.

High-dimensional rank-one nonsymmetric matrix decomposition: the spherical case
TLDR
A replica-symmetric formula is proved for the average mutual information between these vectors and the observations in the high-dimensional regime that goes beyond previous results which considered vectors with independent and identically distributed elements. Expand
