Coefficients and relative inclusion of features in cross-validation of lasso model. Median ($\pm$ median absolute deviation) coefficients (top) and absolute frequency of inclusion of features (bottom) over 10 cross-validation iterations for the best lasso model. From 185 features, the depicted 40 features exhibit a nonzero model coefficient. The average frequency of feature inclusion is represented as horizontal line in the bottom subplot. Line ranges depict MAD (right).
