Learning structured data from unspecific reinforcement
M. Biehl, R. Kuehn, I. -O. Stamatescu
We show that a straightforward extension of a simple learning model based on the Hebb rule, the previously introduced Association-Reinforcement-Hebb-Rule, can cope with "delayed",…
A Solvable Model of a Glass
Reimer Kuehn
An analytically tractable model is introduced which exhibits both, a glass--like freezing transition, and a collection of double--well configurations in its zero--temperature poten…
Finite--Size Scaling Analysis of Generalized Mean--Field Theories
Steffen D. ~Frischat, Reimer Kühn
We investigate families of generalized mean--field theories that can be formulated using the Peierls--Bogoliubov inequality. For test--Hamiltonians describing mutually non--interac…
Critical Behaviour of the Randomly Spin--Diluted 2-d Ising Model --- A Grand Ensemble Approach
R. Kühn
The critical behaviour of the randomly spin-diluted Ising model in two space dimensions is investigated by a new method which combines a grand ensemble approach to disordered syste…
Replica Symmetry Breaking in Attractor Neural Network Models
H. Steffan, R. Kühn
The phenomenon of replica symmetry breaking is investigated for the retrieval phases of Hopfield-type network models. The basic calculation is done for the generalized version of t…
