[technology blog] on continuous learning Author: Chen Wenru 1. Summary When learning new knowledge, people can quickly learn similar knowledge according to the previous knowledge, and can not forget the previous knowledge. While machines, or more accurately neural networks, will have some problems while learning new tasks – catastrophic forgetting. The way to solve this […]
