基于核密度估计的可变码率视频流量预测算法
Prediction Algorithm for VBR Video Traffic Based on Kernel Density Estimation
摘要
Abstract
In order to reduce the difficulty of predicting the real-time Variable Bit Rate(VBR) video traffic, this paper proposes a novel algorithm called VBKDE(Variable Bandwidth Kernel Density Estimation). The algorithm is based on kernel density estimation. It dynamically updates the bandwidth of every sample when the scene change happens so as to accelerate the convergence. Simulation results show that, compared with variable step size normalized least mean square, the algorithm can reduce prediction errors by 10%.关键词
