Collaborative Semantic Occupancy Prediction with Hybrid Feature Fusion in Connected Automated Vehicles

no code implementations12 Feb 2024 Rui Song, Chenwei Liang, Hu Cao, Zhiran Yan, Walter Zimmer, Markus Gross, Andreas Festag, Alois Knoll

Additionally, due to the lack of a collaborative perception dataset designed for semantic occupancy prediction, we augment a current collaborative perception dataset to include 3D collaborative semantic occupancy labels for a more robust evaluation.

FedBEVT: Federated Learning Bird's Eye View Perception Transformer in Road Traffic Systems

1 code implementation4 Apr 2023 Rui Song, Runsheng Xu, Andreas Festag, Jiaqi Ma, Alois Knoll

Our findings suggest that FedBEVT outperforms the baseline approaches in all four use cases, demonstrating the potential of our approach for improving BEV perception in autonomous driving.

ResFed: Communication Efficient Federated Learning by Transmitting Deep Compressed Residuals

no code implementations11 Dec 2022 Rui Song, Liguo Zhou, Lingjuan Lyu, Andreas Festag, Alois Knoll

To address this bottleneck, we introduce a residual-based federated learning framework (ResFed), where residuals rather than model parameters are transmitted in communication networks for training.

Edge-Aided Sensor Data Sharing in Vehicular Communication Networks

no code implementations17 Jun 2022 Rui Song, Anupama Hegde, Numan Senel, Alois Knoll, Andreas Festag

Specifically, when the measurement error from the sensors (also referred as measurement noise) is unknown and time varying, the performance of the data fusion process is restricted, which represents a major challenge in the calibration of sensors.

Federated Learning Framework Coping with Hierarchical Heterogeneity in Cooperative ITS

1 code implementation1 Apr 2022 Rui Song, Liguo Zhou, Venkatnarayanan Lakshminarasimhan, Andreas Festag, Alois Knoll

Considering the individual heterogeneity of data distribution, computational and communication capabilities across traffic agents and roadside units, we employ a novel method that addresses the heterogeneity of different aggregation layers of the framework architecture, i. e., aggregation in layers of roadside units and cloud.
