Comparison of predictive performance (a) and slope coefficients (b) over ten years for different feature combinations trained with the XGBoost regression method among researchers of varying experience levels (junior, mid-level, and senior). (a) illustrates the performance of predicting models using the sMAPE metric. (b) displays the corresponding slope coefficients, indicating the performance change over time. The dark/light blue columns in (b) represent feature combinations, including/excluding prior impact-based features
