Fig. 2

The variation of partial likelihood deviance in response to changes in lambda during the cross-validation process. The dashed line on the left showed the optimal lambda in the LASSO method with the least partial likelihood deviance (A-C). The change of each feature’s coefficients in the LASSO method as lambda changes (D-F). FS CE-T1 (A,D), CE-T1 (B,E), and T2WI (C,F), respectively.
