چکیده

The simultaneous advances in deep learning and the Internet of Things (IoT) have benefited distributed paradigms. Federated is one most promising frameworks, where a server works with local learners to train global model. intrinsic heterogeneity IoT devices, or non-independent identically (Non-I.I.D.) data, combined unstable communication network environment, causes bottleneck that slows convergence degrades efficiency. Additionally, majority weight averaging-based model aggregation approaches raise questions about fairness. In this paper, we propose peer-to-peer federated (P2PFL) framework based on Vision Transformers (ViT) models help solve some above issues classify COVID-19 vs. normal cases Chest-X-Ray (CXR) images. Particularly, clients jointly iterate aggregate order build robust experimental results demonstrate proposed approach capable significantly improving performance an Area Under Curve (AUC) 0.92 0.99 for hospital-1 hospital-2, respectively.

A Hybrid Keyword Search across Peer-to-Peer Federated Databases

The need for Keyword search in databases is suggested both by Web integration with legacy database management system and by dynamic Web publication. However, it sacrifices the inherent meaning of database schema. Web search engines provide clues for resource location on the Web, but have similar semantic problems. The Semantic Web suggests an ideal solution for the semantic problem on the Web. ...

Mediated peer (to peer) learning

Peer learning means learning from and with each other. Collaboration and cooperation in a friendly environment is, however, something that is neither easy nor obvious for students attending the university. Though, different methods and technological solutions can be implemented to facilitate and improve peer learning as well as dialogue and reflection. The aims of this thesis were to study the ...

Peer-to-Peer Botnet Detection Using NetFlow Master Thesis

. Abstract . . Traditional botnets use a centralized communications architecture where all the bots connect to Command and Control (C&C) servers. These servers are the weak point of the botnet, as they are easy targets for take down and monitoring. Peer-to-peer (p2p) botnets have a distributed architecture, which make them more resilient. This research aims at the detection of individual p2p bo...
