Because linear methods are not sufficient to analyze the data with nonlinear patterns, the nonlinear methods KMSE and KFD are hence developed from MSE and FLD, respectively.

由於这两种方法都是线性分类方法，为了能够处理蕴含非线性特徵的实例，因此从最小平方误差法衍生出以核心函数为根基的核心最小平方误差法，另外也从费雪线性区别衍生出以核心函数为根基的核心费雪区别。

It has been proved that Reichardt's Elementary Motion Detector can perform figure-ground discrimination efficiently, and Wavelet transform analysis is similar to the multi-frequency channel of human vision. So we combine EMD, Wavelet transform and Pyramid image processing together, to propose a new motion estimation algorithm. The computer simulation results reveal that the proposed algorithm can well simulate vistual motion evaluation.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
