The paper presents a Bayesian deep learning approach for active exploration in model-based reinforcement learning applied to robot manipulation. By improving model calibration and actively selecting transitions that maximize information gain, the method enhances data efficiency during a preliminary exploration phase. Experiments on a realistic robotic arm simulator demonstrate that the approach achieves comparable performance to existing methods while requiring significantly fewer robot executions.

PrefO2O introduces an offline-to-online latent preference transfer framework that enables zero‑shot preference‑based reinforcement learning on unseen tasks without human feedback. It learns a task‑invariant latent preference space from limited offline preference data, disentangling transferable preference structures from task‑specific variations. The method uses confidence‑weighted optimal transport to generate reliable pseudo‑preference supervision for online reward adaptation, achieving performance that matches or exceeds traditional PbRL methods trained with real human feedback across various robotic manipulation and locomotion benchmarks.
