Before revision:  Our simulation results show that the AVIM not only achieves state-of-the-art  performance compared with other advanced methods but also the output of AVIM for each concept has stable representations during the continual learningprocess .
After revision:  Our simulation results show that the AVIM not only achieves state-of-the-art performance compared with other advanced methods such as OWM, iCaRL and GEM. Moreover, it can generate stable representations of objects during learning .
