Signature gene selection. A Venn diagram between ERBB3-related DEGs and survival-related DEGs. B-C Lasso regression plot (B) and validation plot (C). D Top 20 relatively important genes based on RF algorithm. E The top 13 relatively important genes based on the XGBoost algorithm. F Venn diagrams of the characterized genes identified by the three machine learning algorithms.
