Finite-Time Analysis of On-Policy Heterogeneous Federated Reinforcement Learning

no code implementations27 Jan 2024 Chenyu Zhang, Han Wang, Aritra Mitra, James Anderson

In response, we introduce FedSARSA, a novel federated on-policy reinforcement learning scheme, equipped with linear function approximation, to address these challenges and provide a comprehensive finite-time error analysis.

Skeleton Graph-based Ultrasound-CT Non-rigid Registration

no code implementations14 May 2023 Zhongliang Jiang, Xuesong Li, Chenyu Zhang, Yuan Bi, Walter Stechele, Nassir Navab

Autonomous ultrasound (US) scanning has attracted increased attention, and it has been seen as a potential solution to overcome the limitations of conventional US examinations, such as inter-operator variations.

A Multitask Deep Learning Model for Parsing Bridge Elements and Segmenting Defect in Bridge Inspection Images

1 code implementation6 Sep 2022 Chenyu Zhang, Muhammad Monjurul Karim, Ruwen Qin

Quantitative and qualitative results from evaluating the developed multitask deep model demonstrate its advantages over the single-task-based model not only in performance (2. 59% higher mIoU on bridge parsing and 1. 65% on corrosion segmentation) but also in computational time and implementation capability.

Visual Commonsense in Pretrained Unimodal and Multimodal Models

1 code implementation NAACL 2022 Chenyu Zhang, Benjamin Van Durme, Zhuowan Li, Elias Stengel-Eskin

Our commonsense knowledge about objects includes their typical visual attributes; we know that bananas are typically yellow or green, and not purple.
