Counterfactual Multi-Agent Credit Assignment Optimization Fused with Spatial Causal Adjacency Matrix

Counterfactual Multi-Agent Policy Gradients (COMA) are often hampered by dense, irrelevant noise in the centralized critic, which stems from the full-conditioning assumption in high-dimensional action spaces and results in unstable gradient estimation. To address this fundamental limitation, this paper introduces SCAM-...

Enhancing Visual-Inertial SLAM via Dynamic-Aware Soft Suppression in DBA-Fusion

Visual-Inertial SLAM (VI-SLAM) systems are sensitive to dynamic objects because moving foreground regions may corrupt feature tracking, optical-flow estimation, and subsequent pose optimization. To mitigate this problem, this paper presents a dynamic-aware image-domain soft suppression frontend for DBA-Fusion. The prop...

DUGM-R: Uncertainty-Aware Dynamic Grid Mapping and Risk-Triggered Recovery for Learned Local Navigation

Learned local navigation in crowded indoor environments is sensitive to how dynamic obstacle motion is represented, while collision-prone behaviour may persist after nominal policy training. We present a risk-aware reinforcement-learning framework that addresses these two issues through an uncertainty-aware Dynamic Unc...
