TRACE: Trajectory-robust Admission with Evidence Ordering for Efficient GUI Agents

GUI agents accumulate high-resolution screenshots as the trajectory unfolds, increasing inference latency and memory usage. Training-free visual token pruning can reduce this cost, but cache reuse introduces a fundamental constraint. Once tokens are discarded, the corresponding visual evidence cannot be recovered witho...

FlowPainter: Inpainting Optical Flow via Confidence-Guided Completion

FlowPainter is introduced, a diffusion-based optical flow framework that reformulates dense-flow generation as confidence-guided soft inpainting and offers a practical way to integrate reliable discriminative priors with diffusion-based refinement for optical flow estimation.
