摘要

VBR(Variable Bit Rate)视频信号具有时变性、非线性和突发性等特点

实现该信号通信量的高精度预测是提高信息传输速度和提高网络带宽资源利用效率的重要手段.针对以上问题

本文提出了一种用于VBR视频通信量预测的差分输入支持向量机(SVM:Support Vector Machine)网络模型.该网络模型采用结构风险最小化准则

在最小化经验风险的同时

尽量缩小模型预测误差的上界

从而使网络模型具有更好的推广能力.实验结果表明:支持向量机网络模型的预测误差为0.0018

而梯度径向基函数(Gradient Radial Basis Function:GRBF)神经网络模型的预测误差为0.0029.可以看出

支持向量机网络模型的预测精度要比GRBF网络模型的预测精度高出大约40%.

Abstract

A support vector machine neural network is proposed for performing VBR video traffic prediction.It takes differential signal as the input of the network.According to the criteria of structural risk minimization of SVM

the errors between sample-data and model-data are minimized and the upper bound of predicting error of the model is also decreased simultaneously so that the ability of generalization of the model is much improved.The simulation results show that the prediction error of SVM neural networks is 0.0018

while the prediction error of GRBF neural networks is 0.0029.In prediction precision

SVM neural networks model extended 40% than GRBF model.
