6. Conclusion and future work

This paper propose a new setting for instance incremental learning task where no old data is available and the target is to enhance the base model with only new observations each time. The new IIL setting is more practical in real deployment either in regards of fast and lowcost model updating or data privacy policy. To tackle the proposed problem, a new decision boundary-aware distillation with knowledge consolidation method is presented. Benchmarks based on existing public datasets are established to evaluate the performance. Extensive experiments demonstrate the effectiveness of the proposed method. However, gap between the IIL model and fulldata model still exists. In IIL, the future work can be done in following directions: 1) Narrowing the gap between IIL model and full-data model; 2) Few-shot IIL; 3) A better manner to accumulate knowledge than the proposed KC.
