基于学习向量量化神经网络的软件可靠性预测
乔辉,,邵南
计算机应用 , 2012,
Abstract: ?针对传统的软件可靠性预测模型在实际应用中存在预测泛化性能不佳等问题,提出一种基于学习向量量化(lvq)神经网络的软件可靠性预测模型。首先分析了lvq神经网络的结构特点以及它与软件可靠性预测的联系,然后运用该网络来进行软件可靠性的预测,并基于美国国家航空航天局(nasa)软件数据项目中的实例数据集,运用matlab工具进行了仿真实验。通过与传统预测方法的对比,证明该方法具有可行性和较高的预测泛化性能。

Abstract: 针对当前大多数软件可靠性预测模型预测准确率不高等问题,利用lvq神经网络的非线性运算能力和自适应遗传算法(aga)的参数寻优能力,提出了一种基于aga-lvq的软件可靠性预测模型。首先对待预测的数据用主成分分析((pca)等方法进行预处理以降低维度,去除冗余和错误数据,然后根据自适应遗传算法来计算最优的lvq神经网络初始权值向量,最后运用lvq神经网络进行软件可靠性预测实验。通过与传统方法的对比,证明该方法具有较高的预测准确率。

Abstract: 针对软件可靠性早期预测中软件复杂性度量属性维数灾难问题,提出了一种基于最小绝对值压缩与选择方法(theleastabsoluteshrinkageandselectoperator,lasso)和最小角回归(leastangleregression,lars)算法的软件复杂性度量属性特征选择方法。该方法筛选掉一些对早期预测结果影响较小的软件复杂性度量属性,得到与早期预测关系最为密切的关键属性子集。首先分析了lasso回归方法的特点及其在特征选择中的应用,然后对lars算法进行了修正,使其可以解决lasso方法所涉及的问题,得到相关的复杂性度量属性子集。最后结合学习向量量化(learningvectorquantization,lvq)神经网络进行软件可靠性早期预测,并基于十折交叉方法进行实验。通过与传统特征选择方法相比较,证明所提方法可以显著提高软件可靠性早期预测精度。

Abstract: The prediction accuracy of most current software reliability prediction models is not high. This paper put forward a software reliability prediction model based on AGA-LVQ,which takes advantage of non-linear computing power of the learning vector quantization (LVQ) neural network and parameter optimization capability of the adaptive genetic algorithm (AGA). Firstly,principle components analysis (PCA) preprocessing was used to reduce the dimension of the metrics and remove the redundancy and error data. Secondly, AGA was used to calculate the optimal initial vector weights of the LVQ neural network. Lastly, LVQ neural network was used to do the software reliability prediction experiments. The experiment results indicate that the method has a higher prediction precision than the traditional software reliability prediction model.
