The features are represented on the y-axis, with their relative importance indicated by the spread of SHAP values along the x-axis. By analyzing the SHAP values, inferences can be made to identify which features significantly influence the model's predictions. To optimize the emission wavelength, it is essential to identify the optimal conditions that maintain the variables within the range associated with high positive SHAP values. While the impact of reaction time is less pronounced compared to other factors, shorter reaction times generally correlate with an increase in emission wavelength. Additionally, an increase in particle size, quantum yield, and reaction temperature tends to enhance emission, suggesting their significant role in tuning the optical properties of the synthesized carbon dots.
