Dimensionality reduction with LASSO regression. (A,C) The coefficients of texture features, represented by each colored line, were plotted vs. log (lambda) in the caudate nucleus (CN) and putamen (PU) radiomics signatures, respectively. (B,D) The binomial deviances were plotted vs. log (lambda) in the CN and PU radiomics signatures, respectively. Using 10-fold cross-validation, the red points indicate average values of deviance for each lambda, and the left and right dotted vertical lines correspond to lambda in the minimum criteria and the one standard error of the minimum criteria, respectively.
