DeMUSE通过深度多感官融合与稀疏专家扩展,实现复杂物理互动的高成功率。

摘要:

实现灵巧的具身体验需要深度整合异构的多模态感官输入。然而,当前以视觉为中心的范式往往忽视了力和几何反馈对于复杂任务的重要性。本文提出了DeMUSE,一种深度多模态统一稀疏专家框架,利用扩散变换器将RGB、深度和6轴力整合到统一的序列流中。采用自适应模态特定归一化(AdaMN)来重新校准模态感知特征,缓解表示不平衡并和谐多感官信号的异构分布。为了实现高效的扩展,架构利用了共享专家的稀疏混合专家(MoE),增加模型容量以适应物理先验,同时保持实时控制所需的低推理延迟。联合去噪目标同步合成环境演变和动作序列以确保物理一致性。在仿真和现实世界试验中,DeMUSE实现了83.2%和72.5%的成功率,展示了最先进的性能,验证了深度多感官整合对于复杂物理互动的必要性。

英文摘要:

Realizing dexterous embodied manipulation necessitates the deep integration of heterogeneous multimodal sensory inputs. However, current vision-centric paradigms often overlook the critical force and geometric feedback essential for complex tasks. This paper presents DeMUSE, a Deep Multimodal Unified Sparse Experts framework leveraging a Diffusion Transformer to integrate RGB, depth, and 6-axis force into a unified serialized stream. Adaptive Modality-specific Normalization (AdaMN) is employed to recalibrate modality-aware features, mitigating representation imbalance and harmonizing the heterogeneous distributions of multi-sensory signals. To facilitate efficient scaling, the architecture utilizes a Sparse Mixture-of-Experts (MoE) with shared experts, increasing model capacity for physical priors while maintaining the low inference latency required for real-time control. A Joint denoising objective synchronously synthesizes environmental evolution and action sequences to ensure physical consistency. Achieving success rates of 83.2% and 72.5% in simulation and real-world trials, DeMUSE demonstrates state-of-the-art performance, validating the necessity of deep multi-sensory integration for complex physical interactions.
