As AI progresses, addressing the challenge of continual learning over a diverse range of tasks becomes central. This paper analyzes the performance of continual learning models exposed to long-tail distributions of task sizes and proposes an innovative approach involving optimizer state reuse:

• Focus on underexplored factors: Highlights the role of optimizer states in task learning and retention.
• Devising new datasets: Introduces new synthetic and real-world datasets for assessing long-tail task performance.

Opinion: This research could be a game-changer for developing adaptable AI capable of navigating real-world complexities. The emphasis on long-tail distribution is especially pertinent to medicine, where rare diseases and treatments create a need for algorithms that can learn from scarce data without forgetting common knowledge.
