Dynamic Manifold Hopfield Networks for Context-Dependent Associative Memory
Chong Li, Taiping Zeng, Xiangyang Xue +1
Neural population activity in cortical and hippocampal circuits can be flexibly reorganized by context, suggesting that cognition relies on dynamic manifolds rather than static rep…
Hi-Dyna Graph: Hierarchical Dynamic Scene Graph for Robotic Autonomy in Human-Centric Environments
Jiawei Hou, Xiangyang Xue, Taiping Zeng
Autonomous operation of service robotics in human-centric scenes remains challenging due to the need for understanding of changing environments and context-aware decision-making. W…
Towards a Vision-Language Episodic Memory Framework: Large-scale Pretrained Model-Augmented Hippocampal Attractor Dynamics
Chong Li, Taiping Zeng, Xiangyang Xue +1
Modeling episodic memory (EM) remains a significant challenge in both neuroscience and AI, with existing models either lacking interpretability or struggling with practical applica…
LOG-Nav: Efficient Layout-Aware Object-Goal Navigation with Hierarchical Planning
Jiawei Hou, Yuting Xiao, Xiangyang Xue +1
We introduce LOG-Nav, an efficient layout-aware object-goal navigation approach designed for complex multi-room indoor environments. By planning hierarchically leveraging a global…
