Just-In-Time Scene Graph Growth: Combating Perceptual Saturation in Long-Horizon Robotics

Yue Chang, Rufeng Chen, Yifan Tian, Dazhi Huang, Zhaofan Zhang, Yi Chen, et al.

While 3D Scene Graphs (3DSGs) provide crucial structured representations for embodied agents, conventional Ahead-of-Time, build-everything-then-filter pipelines conflict with the real-time, low-latency demands of edge platforms, inducing a perceptual saturation effect via severe…

LH-AVLN: A Benchmark for Long-Horizon Audio-Visual-Language Navigation

Rufeng Chen, Yue Chang, Zili Shao, Zhaofan Zhang, Li Chen, Hechang Chen, et al.

Embodied navigation is moving toward long-horizon missions, yet existing long-horizon benchmarks are largely acoustically silent, and audio-visual navigation tasks typically focus on a single goal. We introduce LH-AVLN, a benchmark for Long-Horizon Audio-Visual-Language Navigatio…

Towards the Explainability of Temporal Graph Networks via Memory Backtracking and Topological Attribution

Yazheng Liu, Xi Zhang, Sihong Xie, Hui Xiong

Temporal graphs are ubiquitous in real-world applications and Temporal Graph Networks (TGNs) have achieved superior predictive accuracy. Understanding which historical events drive model predictions can enhance trustworthiness of TGNs. Existing explanation methods overlook the me…
