Abstract
Recognition of temporal/dynamical patterns is among the most difficult pattern recognition tasks. In this paper, based on a recent result on deterministic learning theory, a unified framework is proposed for rapid recognition of dynamical patterns. Firstly, it is shown that time-varying dynamical patterns can be effectively represented through deterministic learning. Then, by characterizing the similarity of dynamical patterns based on system dynamics, a dynamical recognition mechanism is proposed. Rapid recognition of dynamical patterns can be implemented when state synchronization is achieved according to a kind of indirect and dynamical matching on system dynamics. The synchronization errors can be taken as the measure of similarity between the test and training patterns.
