For this problem, Funabiki and Takefuji (1992) proposed a parallel algorithm using the maximum neural network. However it is often caught in a local minimum because the maximum neural network is based on the Hopfield neural network. On the other hand, the chaotic NN has the characteristic of escaping from a local minimum. A novel algorithm using the chaotic NN is proposed. In order to confirm the effectiveness of the algorithm, numerical experiments are carried out, and it is confirmed experimentally that the proposal is more effective than the Funabiki and Takefuji algorithm.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.

At every integration step, nonlinear transformation is applied to the driving signal represented as the sum of constant and harmonic waveforms in the phase space. Components of the output waveform that consist of higher harmonics in the phase space are transformed back into time space using universal Chebyshev transformation that does not depend upon the nonlinearity of the component. To enable different values of waveform at the end of the time interval, half-frequency components are inserted into signals. The integration step can be equal to, part of, or a multiple of the oscillation period. The method may use a time step that is hundreds of times larger than in plain transient analysis, for example, in Spice simulation. The time step can be fixed or variable to determine the exact length of the oscillation period.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.

A new and simple estimation scheme for the variances of the white input and output measurement noises is presented which is based on expanding the denominator polynomial of the system transfer function only and makes no use of the average least-squares (LS) errors. The attractive feature of the iterative LS based parametric algorithm thus developed is its improved convergence property. The effectiveness of the developed identification algorithm is demonstrated through numerical illustrations.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.

The first M-PIRE implementation will consume 90 mm/sup 2/ in 0.25 /spl mu/ CMOS technology. It will support real-time video and audio processing of MPEG-4 simple profile or ITU H.26x standards; future designs of M-PIRE will add support for higher MPEG-4 profiles.
