| Abstract: | Grounded on the R open source statistic environment,this paper builds a data mining model on the complex HPLC multi - dimensional fingerprint data with visualization analysis.The result fully reflects that PCA can be used as a model to reveal the principles of multi -dimensional data,and verifies the validity and practicality of principal component and cluster analysis and neural network to reveal the character of multi - dimensional data.Finally,based on the results of PCA and cluster analysis,this paper builds a training network model through techniques of machine learning and other related statistical algorithm to predict the habitat of unknown TCM sample,which supplies sufficient evidences to the TCM quality control. |
