Position: Deployed Reinforcement Learning should be Continual
TL;DR
Reinforcement Learning (RL) systems often follow a train-then-fix approach, leading to inefficiencies as they do not learn during deployment. This position paper argues for a continual RL framework, where agents learn from ongoing interactions and evaluative rewards.
✦ Why It Matters
Engineers can implement continual learning strategies in RL systems to enhance adaptability and performance in changing environments.
Key Takeaways
- Adopt continual learning frameworks for RL applications.
- Identify and address non-stationarity in deployment environments.
- Utilize evaluative rewards to enhance agent learning.
- Shift from static training to dynamic adaptation strategies.
Full Summary
Reinforcement Learning (RL) has become increasingly relevant in real-world applications, yet many systems operate under a train-then-fix paradigm, where agents are static post-training. This position paper advocates for a continual RL approach, which allows agents to learn and adapt while deployed, responding to changes in their environment.
The authors identify four sources of non-stationarity—changes in the environment, user behavior, task dynamics, and agent performance—that necessitate this continual learning. By leveraging evaluative reward signals, agents can improve their performance over time rather than waiting for performance drops to trigger retraining.
The implications of this approach suggest that RL systems can become more robust and efficient in dynamic settings. This shift could lead to more intelligent and adaptable AI applications across various industries.
