Fundamental operating regimes, hyper-parameter fine-tuning and glassiness: towards an interpretable replica-theory for trained restricted Boltzmann machines
Alberto Fachechi, Elena Agliari, Miriam Aquaro +2
We consider restricted Boltzmann machines with a binary visible layer and a Gaussian hidden layer trained by an unlabelled dataset composed of noisy realizations of a single ground…
Immune networks: multi-tasking capabilities near saturation
Elena Agliari, Alessia Annibale, Adriano Barra +2
Pattern-diluted associative networks were introduced recently as models for the immune system, with nodes representing T-lymphocytes and stored patterns representing signalling pro…
Retrieving Infinite Numbers of Patterns in a Spin-Glass Model of Immune Networks
Elena Agliari, Alessia Annibale, Adriano Barra +2
The similarity between neural and immune networks has been known for decades, but so far we did not understand the mechanism that allows the immune system, unlike associative neura…
Controlled Markovian dynamics of graphs: unbiased generation of random graphs with prescribed topological properties
E. S. Roberts, A. Annibale, A. C. C. Coolen
We analyze the properties of degree-preserving Markov chains based on elementary edge switchings in undirected and directed graphs. We give exact yet simple formulas for the mobili…
Constrained Markovian dynamics of random graphs
A. C. C. Coolen, A. De Martino, A. Annibale
We introduce a statistical mechanics formalism for the study of constrained graph evolution as a Markovian stochastic process, in analogy with that available for spin systems, deri…
The XY Spin-Glass with Slow Dynamic Couplings
G. Jongen, D. Bolle, A. C. C. Coolen
We investigate an XY spin-glass model in which both spins and couplings evolve in time: the spins change rapidly according to Glauber-type rules, whereas the couplings evolve slowl…
