“…To enhance the applicability and generalizability of gait signatures, future studies should explore the uniqueness of individual gait signatures in diverse populations, including individuals with injuries, orthopaedic and neurological disorders, who often exhibit higher (intra-subject) variability in their gait patterns. From an ML perspective, the utilization of zero- and few-shot learning approaches [45] , [46] could be promising directions for investigating uniqueness of gait signatures in open-set tasks.…”
