Analytic study of the three-urn model for separation of sand
G. M. Shim, B. Y. Park, J. D. Noh +1
We present an analytic study of the three-urn model for separation of sand. We solve analytically the master equation and the first-passage problem. We find that the stationary pro…
The Blume-Emery-Griffiths neural network: dynamics for arbitrary temperature
D. Bolle, J. Busquets Blanco, G. M. Shim +1
The parallel dynamics of the fully connected Blume-Emery-Griffiths neural network model is studied for arbitrary temperature. By employing a probabilistic signal-to-noise approach,…
Optimal Capacity of the Blume-Emery-Griffiths perceptron
D. Bolle, I. Perez Castillo, G. M. Shim
A Blume-Emery-Griffiths perceptron model is introduced and its optimal capacity is calculated within the replica-symmetric Gardner approach, as a function of the pattern activity a…
Local field dynamics in symmetric Q-Ising neural networks
D. Bolle', G. M. Shim
The time evolution of the local field in symmetric Q-Ising neural networks is studied for arbitrary Q. In particular, the structure of the noise and the appearance of gaps in the p…
Q-Ising neural network dynamics: a comparative review of various architectures
D. Bolle, G. Jongen, G. M. Shim
This contribution reviews the parallel dynamics of Q-Ising neural networks for various architectures: extremely diluted asymmetric, layered feedforward, extremely diluted symmetric…
