Humans can continuously acquire new skills and knowledge by exploiting existing ones for improved learning, without forgetting them.
'Continual learning' in machine learning aims to learn new information while preserving the previously acquired knowledge.
A new method is proposed that interleaves tasks based on their 'learning progress' and energy consumption, mimicking human task learning.
Experiments conducted with a robot learning setting show that the proposed method achieves better performance and reduces energy consumption for learning tasks.
