1. BrainMem: Brain-Inspired Evolving Memory for Embodied Agent Task Planning
- 方向：arXiv/机器人学
- 摘要：arXiv:2604.16331v1 Announce Type: new Abstract: Embodied task planning requires agents to execute long-horizon, goal-directed actions in complex 3D environments, where success depends on both immediate perception and accumulated experience across tasks. However, most existing LLM-based planners are stateless and reactive, operating without persistent memory and therefore repeating errors and strug…

However, existing approaches are often restricted to narrow age ranges and single-modality MRI data, limiting their capacity to capture the coordinated macro- and microstructural changes that unfold across the human lifespan. To address these limi…
