Fig. 3From: The application of different machine learning models based on PET/CT images and EGFR in predicting brain metastasis of adenocarcinoma of the lungThe LASSO method was used to screen CT radiomics features. Note: Fig a: MSE path, Represents the mean squared error of different lambda values for each cross-validation;Fig b: LASSO path, It indicates the change of the regression coefficient of the independent variable when λ selects different values.
