    Inference-time Policy Steering via Vision and Touch

    Researchers have developed ViTaL, a new framework for steering pre-trained generative robot policies during deployment. This system uses both visual and tactile information to refine candidate actions before execution, addressing limitations of vision-only methods in contact-rich manipulation tasks. ViTaL formulates multimodal guidance as a bi-level optimization problem, with visual sampling for long-horizon mode selection and tactile-guided diffusion editing for short-horizon refinement. The framework incorporates a visuo-tactile latent world model and learned verifiers, including a text-conditioned tactile reward, to improve success rates in real-world manipulation tasks. AI

    IMPACT Enhances robot manipulation capabilities by integrating multimodal sensory feedback for improved action selection and refinement.

    VITAL: Visual-Semantic Dual Supervision for Enhanced and Interpretable Latent Reasoning in Medical MLLMs

    Researchers have introduced VITAL, a novel framework designed to enhance latent reasoning in medical multimodal large language models (MLLMs). This approach addresses issues like modality collapse and lack of interpretability by employing a dual supervision strategy. VITAL uses an auxiliary text decoder and a visual projector, both of which can be detached during inference to maintain efficiency while allowing for post-hoc interpretability through textual and visual explanations. The framework has demonstrated state-of-the-art performance on various benchmarks, outperforming existing methods and even competing with trillion-parameter proprietary models. AI

    IMPACT Enhances interpretability and performance of medical AI systems, potentially improving clinical decision-making.
