Feature importance and Grad-CAM. (a) SHAP values of each parameter in the images of the infants with unstable hips. The position indicates the SHAP value, and higher SHAP values signify a greater positive impact on the outcome. The top-ranked parameters have higher SHAP values. The color of each point in the plot represents the relative magnitude of the feature value, while the position indicates the SHAP value. (b) Representative images of positive and negative cases in which Grad-CAM heat-map was integrated with hROIs. SHAP: the SHapley Additive exPlanations; hROIs: hip regions of interest. Contr: contralateral.
