Offline RL
A reinforcement learning paradigm that learns policies solely from static datasets without requiring online interaction, suited to scenarios where interaction is costly or dangerous. Core challenges include out-of-distribution action overestimation and offline-to-online fine-tuning.
Timeline (last 90 days)
Industrial deployment cases of pure offline RL are relatively limited, and it serves more as a supplement to online RL.
Offline RL trains a policy only on a pre-collected fixed dataset, with no further interaction with the environment during training, and its core advantage is that the training process is fully reproducible and auditable.
The real divergence between offline RL and online continuous RL lies in "what gates the weights": offline RL's gate is the release process itself (human review, offline evaluation, canary release), while online continuous RL's gate is an automatic threshold.
Online continuous RL introduces new failure modes: the gate being bypassed, threshold drift, and unclear rollback trigger conditions, problems that do not exist in offline RL because in offline RL the model and serving are decoupled.
