RBF Network-Based Chaotic Time Series Prediction and It's Application in Foreign Exchange Market

Li-li Ma, Xu-song Xu
The foreign exchange market is a chaotic dynamic system. We apply the RBF network-based chaotic time series prediction on the daily USD/RMB exchange rate. We apply the RBF network and phase space reconstruction to find the optimal embedding dimension in the foreign exchange market from the point view...

Optimization of DHMM Based on Chaotic Migration-Based GA for Chinese Signature Verification

Zhenhua Wu
In this paper, Genetic Algorithm (GA) is used to train the parameters of Discrete Hidden Markov Model (DHMM). To overcome the premature convergence in GA, a chaotic migration strategy is introduced to the pseudo parallel genetic algorithm to increase the diversity of population. Because the GA’s evolution...

Synchronization for Chaotic Systems with Different Structure and Unknown Parameters

Qingying Miao, Yang Tang, Suojun Lu, Jianan Fang
In this article, we demonstrate the problem of synchronization for a class of chaotic systems with different structure and unknown parameters. A nonlinear controller is developed. We estimate the parameters and construct the proper controller with these estimations. It is also found that this scheme...

Predicting Short-time Traffic Flow Using Volterra Adaptive Model

Yumei Zhang, Shiru Qu, Kaige Wen
An adaptive method for predicting short-time traffic flow, which is based on phase space reconstruction and Volterra series, was proposed. We first employed Lyapunav exponent method based small data sets to validate that chaos exists in traffic flow. Then, phase space reconstruction for traffic flow...

Chaotic Analysis on Series of Groundwater Depth in Hetao Irrigation District

WEI-GUANG WANG
The chaotic behavior of groundwater depth time series is investigated using correlation dimension method and the CAO method based on the reconstruction of phase-space. A groundwater depth time series, each five days series of 25 years (with a total of 1793 values) observed in Hetao irrigation district...

A Novel Active Pining Control for Synchronization of Uncertain Lü Chaotic Systems

Qu Shao-cheng
This paper discusses the synchronization of uncertain Lü chaotic systems. Based on the idea of active control, a novel active pining control strategy is presented, which only need a state of uncertain Lü chaotic systems. This controller can achieve synchronization between a salve system and a master...

A Novel Image Steganography Using Chaotic Map and Visual Model

Peipei Liu, Zhongliang Zhu, Hongxia Wang, Tianyun Yan
A novel image steganography method using chaotic map and human visual model is presented in DCT domain. Firstly each 8×8 image block is performed Discrete Cosine Transform, then the location of image block that is embedded secret message is determined by the chaotic map. Finally the secret message is...
