Soybean leaf parameter estimation based on the Cat Boost model. The R2, MAE, and ATPA values are the result of tenfold cross-validation. The x-axis labels represent different input variables for Cat Boost M1-M7. M1: SCA1; M2: SSC; M3: SPA1; M4: SCA1 + SPA1; M5: SCA1 + SSC; M6: SPA1 + SSC; and M7: SPA1 + SCA1 + SSC
