…Real-time Autoregressive Video Extrapolation with Consistency-model GRPO Published on May 14 Submitted by Yanzuo Lu on May 15 MVP Lab Authors: Yanzuo Lu , , Abstract RAVEN enables real-time video generation…
…Furthermore, it estimates an adaptive per-problem target length online based on the model's own correct rollouts, applying a symmetric efficiency reward that penalizes both overthinking and over-compression. Evaluated on…
…We propose On-Policy Representation Distillation (OPRD), which lifts distillation into hidden-state space by aligning student and teacher representations across selected layers on the same rollouts , bypassing the LM head entirely…
…sparse sequence-level reward should train models where exploration is productive, while dense token-level teacher reward should be used where the aim is to compress behavior into a smaller model. In…
…For each condition, S GRPO samples a supergroup of candidate sets, compares their diversity under the same condition, and redistributes the group diversity reward to individual rollouts through leave-one-out diversity…
…Generated by Qwen/Qwen2.5-Coder-32B-Instruct When pretrained VLA policies are fine-tuned through online RL , each rollout episode produces only a single binary outcome (success or failure), yet the…

…the prompt, concept, model, and steering configuration. Finding the regime and boundaries of successful steering typically requires expensive grid searches and post-hoc evaluation of full autoregressive rollouts . In this work, we…
…FlowBP keeps a no-gradient cached rollout for sampling, then builds a lightweight backward surrogate from cached and selectively re-forwarded velocities. This view separates four choices: the reward-model input, active…
