目前移动网络优化一般基于小区进行网络质量评估及预测,遵循“升维研究,降维实施”的研究思路,提出了兴趣点(point of interest,POI)网络质量的柔性评价体系,但其涉及较多网络关键绩效指标(key performance indicator,KPI),导致POI网络综合质量评价体系较为庞杂且预测精度不高,为提高POI网络质量预测精准性,采用核主成分分析(kernel principal component analysis,KPCA)算法对反向传播(back propagation,BP)神经网络的输入变量进行相关性压缩,简化了BP神经网络结构,然后通过遗传算法(genetic algorithm,GA)优化了BP神经网络连接权值及阈值参数。与传统BP神经网络预测结果进行对比,在预测准确度方面提高了10.90%,均方误差性能显著降低,对研究POI网络质量的预测可起到较好的支撑作用。
At present
in network optimization
network quality evaluation and prediction are generally based on communities
and a flexible evaluation system for POI network quality was proposed following the research idea of “research on dimensionality increase and implementation of dimensionality reduction”.However
it involves many network KPI
resulting in a relatively complex evaluation system for POI network comprehensive quality and low prediction accuracy.In order to improve the prediction accuracy of POI network quality
KPCA was used to compress the correlation of input variables of BP neural network
the structure of BP neural network was simplified
and then the connection weights and threshold parameters of BP neural network were optimized through GA.Compared with the prediction results of traditional BP neural network
the prediction accuracy is improved by 10.9%
and the mean square error performance is significantly reduced
it can play a better supporting role in the prediction of POI network quality.
