AI can't learn new things forever an algorithm can fix that
00:46 Old AIs can\u2019t learn new tricks
An algorithm that reactivates dormant \u2018neurons\u2019 in deep learning based AIs could help them overcome their inability to learn new things and make future systems more flexible, research has shown. AIs based on deep learning struggle to learn how to tackle new tasks indefinitely, making them less adaptable to new situations. The reasons for this are unclear, but now a team has identified that \u2018resetting\u2019 parts of the neural networks underlying these systems can allow deep learning methods to keep learning continually.
