“…Current research. The study of incremental few-shot learning has just started [47,41,60,9,8,34,59]. Current works mainly borrow ideas from research in incremental learning to overcome the forgetting problem, by enforcing strong constraints on model parameters to penalize the changes of parameters [34,28,56], or by saving a small amount of exemplars from old classes and adding constraints on the exemplars to avoid forgetting [40,20,4].…”
