Performance comparison for CCLE pharmacogenomics data. (A) Predictability score with WRMSE metric of LASSO, Ridge, SGSR with KEGG, Biocarta, NCI/Nature, GO-BP and GO-MF pathways using EXP data across the 24 CCLE drugs, (B) Performance discrepancy between benchmarked LASSO, Ridge, and SGSR models with five available pathway databases with EXP; (C) Predictability score with WRMSE metric of LASSO, Ridge, SGSR with KEGG, Biocarta, NCI/Nature, GO-BP and GO-MF pathways with COPY across the 24 CCLE drugs, (D) Performance discrepancy between benchmarked LASSO, Ridge and SGSR models with five available pathway databases using COPY data.
