Analysis of adaptive threshold method. The size of the legends in the feature space represents the value of the DDI. The SVM classifiers with default hyperparameters along with the top five features selected in the pilot study were employed to generate feature space and decision function. Classifiers and features need to be reselected throughout the actual developing of the individual-specific model. RWF: Recessive weak foot; DWF: Dominant weak foot; DDI: Distribution Difference Index
