This article proposes a data sorting method via the EM algorithm, for the purpose of mining high-quality decisions by performing data reasoning in a database with incomplete, noisy and uncertain data.
针对存在不完整、含噪声和不确定数据的数据库，通过挖掘高质量的决策，对数据库的数据进行推理，提出了一种基于EM算法的数据清理方法。
The number of log items used in electrofacies analysis is uncertain in different geological areas, so application of electrofacies analysis software based on static database has many limitations.
由于研究区域地质情况的不同，测井相分析中应用的测井项目数不确定，因此基于原有静态数据库建立的测井相分析软件在应用上具有极大的局限性。
