An inference problem in a mismatched setting: a spin-glass model with Mattis interaction

  title={An inference problem in a mismatched setting: a spin-glass model with Mattis interaction},
  author={Francesco Camilli and Pierluigi Contucci and Emanuele Mingione},
The Wigner spiked model in a mismatched setting is studied with the finite temperature Statistical Mechanics approach through its representation as a Sherrington-Kirkpatrick model with added Mattis interaction. The exact solution of the model with Ising spins is rigorously proved to be given by a variational principle on two order parameters, the Parisi overlap distribution and the Mattis magnetization. The latter is identified by an ordinary variational principle and turns out to concentrate… Expand

Statistical limits of dictionary learning: random matrix theory and the spectral replica method
A novel combination of the replica method from statistical mechanics together with random matrix theory, coined spectral replica method, is introduced to conjecture variational formulas for the mutual information between hidden representations and the noisy data as well as for the overlaps quantifying the optimal reconstruction error.

Free energy in the mixed p-spin models with vector spins
Using the synchronization mechanism developed in the previous work on the Potts spin glass model, arXiv:1512.00370, we obtain the analogue of the Parisi formula for the free energy in the mixed evenExpand
A mechanical approach to mean field spin models
Inspired by the bridge pioneered by Guerra among statistical mechanics on lattice and analytical mechanics on 1+1 continuous Euclidean space-time, we built a self-consistent method to solve for theExpand
On the mixed even-spin Sherrington–Kirkpatrick model with ferromagnetic interaction
We study a spin system with both mixed even-spin Sherrington-Kirkpatrick (SK) couplings and Curie-Weiss (CW) interaction. Our main results are: (i) The thermodynamic limit of the free energy is givenExpand

About the Almeida-Thouless transition line in the Sherrington-Kirkpatrick mean-field spin glass model
We consider the Sherrington-Kirkpatrick model and we prove that the quenched free energy per spin is strictly larger than the corresponding replica symmetric approximation, for all values of theExpand
Spin Glass Computations and Ruelle’s Probability Cascades
We study the Parisi functional, appearing in the Parisi formula for the pressure of the SK model, as a functional on Ruelle's Probability Cascades (RPC). Computation techniques for the RPCExpand

The Griffiths inequalities for Ising spin-glass models with Gaussian randomness of non-vanishing mean are proved using properties of the Gaussian distribution and gauge symmetry of the system. TheseExpand
Surface Terms on the Nishimori Line of the Gaussian Edwards-Anderson Model
For the Edwards-Anderson model we find an integral representation for some surface terms on the Nishimori line. Among the results are expressions for the surface pressure for free and periodicExpand
Mean field models for spin glasses
Translation from physics: ‘Glass’: a material which is hard and inflexible (like a solid) but is not completely ordered or lattice-like in its microscropic structure (thus, unlike a crystal or simpleExpand
