针对局部异常因子(local outlier factor,LOF)异常检测算法时间空间复杂度高、对交叉异常及低密度簇周围异常点不敏感等局限,提出了基于近邻搜索空间提取的LOF异常检测算法(isolation-based data extracting LOF,iDELOF),将基于隔离思...针对局部异常因子(local outlier factor,LOF)异常检测算法时间空间复杂度高、对交叉异常及低密度簇周围异常点不敏感等局限,提出了基于近邻搜索空间提取的LOF异常检测算法(isolation-based data extracting LOF,iDELOF),将基于隔离思想的近邻搜索空间提取(isolation-based KNN search space extraction,iKSSE)前置于LOF算法,以高效剪切掉大量无用以及干扰数据,获得更加精准的搜索空间。基于此完成了理论以及4组实验分析,每组实验分别进行iDELOF算法与LOF、iForest、iNNE等多种典型算法的对比分析。结果表明:iDELOF算法通过拉大正异常点局部离群因子的差距,增强了对交叉异常以及低密度簇周围异常点的识别能力,提升了LOF的检测效果;iDELOF算法在识别轴平行异常方面与LOF同样具有明显优越性;iDELOF算法通过iKSSE所获数据子集显著小于原数据集,多数子集数据量小于原数据集的1%,因此iDELOF的时间空间复杂度显著降低,且原数据集数据量越大,优越性越明显,当数据量足够大时,iDELOF算法的运行时间将低于IF算法。展开更多

Methods:The internal consistency,the test-retest reliability and the criterion-related validity of the Quality of Life Scale were examined based on the data of 545 breast cancer patients and the control group.Results:The Cronbach α of the total scale was 0.99;the test-retest reliability was 0.83;The scores of the benign breast tumour group were higher than those of the malignant breast tumour group in subscales of Physical Well Being, Psychological Well Being , and Social Well Being.The correlation coefficient between the quality of marriage and the quality of life is 0.45 and 0.33 for the two groups respectively( P <0.01). Conclusion: The Quality of Life Scale for Breast Caner Patients had acceptable reliability and validity.展开更多
