Methodology As shown in Fig. 2 (a), the occurrence of concept drift in new observations leads to the emergence of outer samples that the existing model fails on. The new IIL has to broaden the decision boundary to these outer samples as well as avoiding the catastrophic forgetting (CF) on the old boundary. Conventional knowledge distillation-based methods rely on some preserved exemplars [22] or auxiliary data [33, 34] to resist CF. However, in the proposed IIL setting, we have no access to any old data other than new observations. Distillation based on these new observations conflicts with learning new knowledge if no new parameters are added to the model. To strike a balance between learning and not forgetting, we propose a decision boundary-aware distillation method that requires no old data. During learning, the new knowledge learned by the student is intermittently consolidated back to the teacher model, which brings better generalization and is a pioneer attempt in this area. Authors:
