CT-NeRF: Incremental Optimizing Neural Radiance Field and Poses with Complex Trajectory

no code implementations22 Apr 2024 Yunlong Ran, Yanxu Li, Qi Ye, Yuchi Huo, Zechun Bai, Jiahao Sun, Jiming Chen

In this pipeline, we first propose a local-global bundle adjustment under a pose graph connecting neighboring frames to enforce the consistency between poses to escape the local minima caused by only pose consistency with the scene structure.

Mutual Information as Intrinsic Reward of Reinforcement Learning Agents for On-demand Ride Pooling

no code implementations23 Dec 2023 Xianjie Zhang, Jiahao Sun, Chen Gong, Kai Wang, Yifei Cao, Hao Chen, Yu Liu

The emergence of on-demand ride pooling services allows each vehicle to serve multiple passengers at a time, thus increasing drivers' income and enabling passengers to travel at lower prices than taxi/car on-demand services (only one passenger can be assigned to a car at a time like UberX and Lyft).

Prometheus: Infrastructure Security Posture Analysis with AI-generated Attack Graphs

no code implementations20 Dec 2023 Xin Jin, Charalampos Katsis, Fan Sang, Jiahao Sun, Elisa Bertino, Ramana Rao Kompella, Ashish Kundu

In this paper, we propose Prometheus, an advanced system designed to provide a detailed analysis of the security posture of computing infrastructures.

zkFL: Zero-Knowledge Proof-based Gradient Aggregation for Federated Learning

no code implementations4 Oct 2023 Zhipeng Wang, Nanqing Dong, Jiahao Sun, William Knottenbelt

Federated Learning (FL) is a machine learning paradigm, which enables multiple and decentralized clients to collaboratively train a model under the orchestration of a central aggregator.
