Figure 9.
The image contains five bar charts labelled, a, to, e, each illustrating the relative importance of various variables. The variables include R H, f c m 28, w by c m, V by S, t c, C c m, T, and T c u r. Each bar represents the magnitude of importance, with R H demonstrating a dominant presence in all charts. The charts are structured vertically, with the categories listed on the vertical axis and the relative importance on the horizontal axis, ranging from 0 to 100. The bars are evenly formatted, extending horizontally to reflect their significance, allowing a clear comparison of the different variables across the charts.Importance of features in total shrinkage prediction by ML methods: (a) DT; (b) RF; (c) ET; (d) GB; (e) XGBoost
