Scope-WM: Scoped Computation for Efficient Visual World Models

Chunzheng Li, Zesheng Jia, Hongda Zhang وآخرون · 2026

Visual world models enable robotic planning by predicting future observations, but dense latent-state propagation and sample-intensive trajectory optimization incur high inference latency and peak memory usage, limiting real-time deployment on resource-constrained platforms. Existing sparse world-model acceleration met …

Uncertainty-Guided Sparse Refinement for Action Chunking Transformer Policies

Chenyang Wang, Yuntian Wang, Xiaoxiong Yang وآخرون · 2026

Learning chunk-based visuomotor policies for long-horizon robot manipulation remains challenging. Recent action-chunking methods have shown promising performance by predicting temporally extended action sequences. However, their failures are often dominated by prediction errors at a small number of critical timesteps r …
