Cancer Gene Expression Data Attribute Partial Ordered Representation And Knowledge Discovery

  In this paper,basic concepts and the related definitions of attribute partial-ordered structure diagram have been researched,and a scheme of knowledge discovery to collect new information from cancer gene expression data has been proposed,which was based on the feature selection and attribute partialordered structure diagram.Then the resource of lung adenocarcinoma gene expression data to be processed has been introduced in the paper.Both the T-test method and the Elastic net method have been used in the feature gene selection of lung adenocarcinoma gene expression data,and a total of 35 feature genes have been selected.This process sharply reduced the dimension of the data set.Finally,the c# program has been applied to disperse the data in order to generate the form of binary formal context,then the structural partial-ordered attribute diagram was generated,and the knowledge discovery has been produced based on the distribution and aggregation hierarchy diagram.
