Performance of DDI and adaptive threshold method. a t-SNE visualization of the feature space for individual with high DDI. b DDI between LA and HA groups, with significant difference indicated by *. c Confusion matrix illustrating the effectiveness of the adaptive threshold method in distinguishing between LA and HA. DDI Distribution difference index, HA High accuracy group, LA Low accuracy group, RWF Recessive weak foot, DWF Dominant weak foot
