查询词典 simulated data

When it comes to the local prediction of chaotic time series, owing to the fact that the fixed embedding dimension、the number of the nearest neighbours and regularization parameters can cause the added prediction error,we give the adaptive local linear method and discuss the adaptive selection method of regularization parameters, the advantage of which is tested by the Henon map and Lorenz system simulated data and the integrated index in stock market of Shanghai, to show its practicable value.

According to the characteristics presented by armed helicopters during cruising or searching for ground targets, this paper has established the mean-square deviation stationary random model of helicopter tracks. It is an important method to decorrelate the measure noise by estimating the parameters of the color noise online. Kalman filtering and forecasting have been made with helicopter tracks. The simulated study has been carried out on helicopter tracks under the condition of color noise. It is very difficult to get an accurate and reliable prediction when the data is very limited. The paper make use of the theory of grey system to resolve the problem of prediction of helicopter tracks, establishing the GM model of grey systems and the cumulative residual error model of n degree, then correcting the GM forecast model. In the period of sampling, GM model and residual error model have been established on line to improve prediction precision.
