EIMC: Efficient Instance-Aware Multi-Modal Collaborative Perception

ICRA 2026poster

Multi-modal collaborative perception calls for great attention to enhancing the safety of autonomous driving. However, current multi-modal approaches remain a ``local fusion to communication” sequence, which fuses multi-modal data locally and needs high bandwidth to transmit an individual's feature …

GGBall: Graph Generative Model on Poincaré Ball

ICLR 2026poster

Generating graphs with hierarchical structures remains a fundamental challenge due to the limitations of Euclidean geometry in capturing exponential complexity. Here we introduce GGBall, a novel hyperbolic framework for graph generation that integrates geometric inductive biases with modern generati…

Is Discretization Fusion All You Need for Collaborative Perception?

ICRA 2025

Collaborative perception in multi-agent system enhances overall perceptual capabilities by facilitating the exchange of complementary information among agents. Current mainstream collaborative perception methods rely on discretized feature maps to conduct fusion, which however, lacks flexibility in

ProDiff: Prototype-Guided Diffusion for Minimal Information Trajectory Imputation

ICML 2025poster

Trajectory data is crucial for various applications but often suffers from incompleteness due to device limitations and diverse collection scenarios. Existing imputation methods rely on sparse trajectory or travel information, such as velocity, to infer missing points. However, these approaches assu…
