Complex dynamics in learning systems

Wong, K.Y. Michael; Li, S; Tong, Y.W - In: Physica A: Statistical Mechanics and its Applications 288 (2000) 1, pp. 397-401

To describe the dynamics of learning an input–output relation from a set of examples, the evolution of an appropriate choice of macroscopic dynamical variables have to be found. Recent progress in on-line learning only addresses the often unrealistic case of an infinite training set. For...
