Phase Transitions in Self-Organized Feature Maps

R. Der, M. Herrmann

Research output: Chapter in Book/Report/Conference proceedingChapter


We present an analytical study of symmetry-breaking phenomena in Kohonen’s self-organized feature map (SOFM) that occur due to a topological mismatch between the input space and the neuron setup. We give a microscopic derivation for the time dependent Ginzburg-Landau equations describing the behavior of the order parameter close to the critical point where the phase transition takes place.
