Online Learning
A training paradigm in machine learning in which a model can update its parameters in real time or near real time based on new data. It differs from batch offline updating and suits recommendation scenarios that require rapid response.

Self-normalized techniques were first widely used in the analysis of confidence bounds for online learning and bandit problems, and were later extended to martingale sequences.
The paper proposes possible future research directions, including extending the results to weakly dependent settings, exploring applications of reverse KL tensorization to other concentration phenomena, and studying the specific algorithmic implications of this inequality in online learning or high-dimensional statistics.
This separation result echoes a series of computational lower bound works in online learning and online convex optimization in recent years, confirming the general phenomenon that "statistical optimality does not necessarily imply computational feasibility."
For the online learning setting, every consistent online learner achieves the optimal regret bound.
"Immediate response" requires the recommender system to shift to an online learning or real-time inference architecture, needing to complete topic mapping, recompute ranking scores and instantly override old results within milliseconds to seconds, usually relying on vector retrieval and a ranking layer that can be updated in real time.
Means of addressing concept drift include online learning, sliding window retraining, and drift detection algorithms (such as ADWIN and DDM).
OpenClaw-RL is designed specifically for live traffic, with the policy updated directly from the conversation itself, and the reward signal is a binary value read from the user's next-turn response.
Online learning mechanisms carry an inherent risk: if feedback signals are noisy or systematically biased, the optimization process may produce negative drift, causing the system to degrade over time.
