Research of time series pattern finding based on artificial neural network
Yuqing Peng, Yu Zhang, Hai-Shan Tian · 2004
In this paper, a new way of time-series pattern finding is presented. It fits the time-series curve with sequence of straight lines and the line's arctg is obtain by a piecewise linear approximation. The arctg is regarded as input sample, and artificial neural network and hierarchical processing technology is applied. The experiments prove that the classification accuracy based on ANN is improved.
