local interaction effects of top 8 block morphology variables on urban innovation vitality. The SHAP interaction values for the top eight influential factors and their most relevant factors. The series of scatter plots illustrate the interaction effects between pairs of demographic characteristics on urban innovation vitality. Each plot shows how the SHAP value (on the left y-axis) for one feature (on the right y-axis) changes in relation to another feature (on the x-axis). Blue Dots: indicating a lower impact on the predictive outcome when both features are considered together. Red Dots: suggesting a higher impact on the predictive outcome when considering the interaction of both features.
