Fig. 1From: CT radiomics-based long-term survival prediction for locally advanced non-small cell lung cancer patients treated with concurrent chemoradiotherapy using features from tumor and tumor organismal environmentSchematic overview of the integrated feature selection and model training (IFSMT) approach. IFSMT approach consisted of five steps: (1) volumetric data pre-processing; (2) delineation; (3) feature extraction; (4) integrated feature selection and model training; (5) model validation using leave-one-out cross-validation (LOOCV).Back to article page
