In the previous work, we have addressed the problem of identifying the differentiation process of myoblasts under electric field stimulation using convolutional neural networks. Then, we observed that the VGG19-based model achieved high accuracy for cell classification by using spatial features around their protrusions. In this study, we first evaluate the applicability of the VGG19-based model using the newly obtained dataset. Next, we apply an existing continual learning method, called EWC, to incrementally update the model with the new dataset. It will be infeasible to re-learn all the dataset which has been generated so far, as the amount of cell images to be analyzed is continuously increasing. Here, we aim at clarifying the feasibility of the existing continual learning method. Through the experimental result with visualization by Grad-CAM, we found that the EWC model concentrated different receptive fields which caused a significant decrease of its prediction accuracy, compared with the re-learning model.
