The invention provides a method based on Pearson's collinearity selection (PCS). The method is used for screening features closely related to a target
phenotype from high-dimensional
genome data. According to the PCS method, by calculating Pearson's correlation coefficients among the features, redundant features are effectively removed, the multi-collinearity problem is reduced, the quality of
feature selection is remarkably improved, and the stability of
model prediction is enhanced. The method is particularly suitable for the fields of
genotype and
phenotype correlation analysis and the like, and can optimize the
data processing and analysis process. In addition, the PCS method has high cross-
population adaptability.
Feature selection and prediction
verification are carried out on data sets of multiple populations, it is proved that
multiple models can keep consistent good prediction performance among different data sets by using the PCS method, and the excellent generalization ability is shown. The method not only can effectively predict the
phenotype of a single
population, but also can be successfully applied to prediction tasks of other populations, and the application range of the method in the fields of
precision medicine,
crop breeding and the like is further widened. Compared with a traditional
feature selection method, the PCS method has the advantages that feature redundancy is reduced, meanwhile, features highly related to the target phenotype can be better reserved, the prediction precision of the model is remarkably improved, and more efficient and reliable
technical support is provided for
genome data analysis.
