A new concept for unsupervised learning based upon examples in(cid:173) troduced to the neural network is proposed. Each example is con(cid:173) sidered as an interpolation node of the velocity field in the phase space. The velocities at these nodes are selected such that all the streamlines converge to an attracting set imbedded in the subspace occupied by the cluster of examples. The synaptic interconnections are found from learning procedure providing selected field. The theory is illustrated by examples.

We rigorously establish a close relationship between message passing algorithms and models of neurodynamics by showing that the equations of a continuous Hop- (cid:2)eld network can be derived from the equations of belief propagation on a binary Markov random (cid:2)eld. As Hop(cid:2)eld networks are equipped with a Lyapunov func- tion, convergence is guaranteed. As a consequence, in the limit of many weak con- nections per neuron, Hop(cid:2)eld networks exactly implement a continuous-time vari- ant of belief propagation starting from message initialisations that prevent from running into convergence problems. Our results lead to a better understanding of the role of message passing algorithms in real biological neural networks.
