The connection matrix of the Ising model on a d-dimensional hypercube is investigated. In addition to the interactions between the nearest neighbors, the interactions between the next-nearest neighbors are taken into account. For such a matrix, the e

The Hopfield model effectively stores a comparatively small number of initial patterns, about 15% of the size of the neural network. A greater value can be attained only in the Potts-glass associative memory model, in which neurons may exist in more

We study the dependence of the result of learning on the dynamic threshold H in the Hopfield neural network model. We obtain rigorous results relating the quality of learning to the threshold.

We consider the low binding energy part of ARPES of strongly correlated systems. We map from realistic Anderson-lattice p-d Hamiltonian into spin-fermion (Kondo-lattice) model and derive an analytical expression that relates photoemission intensity f

We study the set of fixed points of a Hopfield-type neural network with a connection matrix constructed from a high-symmetry set of memorized patterns using the Hebb rule. The memorized patterns depending on an external parameter are interpreted as d

Neural networks with two different connection matrices are investigated: the Hebbian and the projection matrix. The structure of the stable points of such networks is investigated, and a method for direct calculation of all stable points is proposed.

We analyze the two-dimensional spin-fermion model in the strong coupling regime relevant to underdoped cuprates. We recall the set of general sumrules that relate moments of spectral density and the imaginary part of fermion self-energy with static c
