  1. 1. Fault-Tolerant Over-the-Air Federated Learning with Clustered Aggregation : Using a hierarchical architecture with hybrid digital and analog communication, to deal with byzantine users in Federated Learning over wireless networks.

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :David Nordlund; [2023]
    Nyckelord :federated learning; aircomp;

    Sammanfattning : Rapid advancements in modern AI applications have placed unprecedented demands on large-scale connectivity and data aggregation. The vision of Internet-of-Things (IoT) is supported by a massive amount of distributed sensors and wireless devices that generate useful data for these applications. LÄS MER

  3. 2. Distributed Robust Learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Akhil Yerrapragada; [2021]
    Nyckelord :Byzantine resilient decentralized training; Gradient aggregation rules; α; f Byzantine resilience; Fault tolerance; Ring all-reduce.; Byzantinsk motståndskraftig decentraliserad träning; Gradientaggregeringsregler; α; f Byzantinsk motståndskraft; Feltolerans; Ring allreducera.;

    Sammanfattning : Accuracy obtained when training deep learning models with large amounts of data is high, however, training a model with such huge amounts of data on a single node is not feasible due to various reasons. For example, it might not be possible to fit the entire data set in the memory of a single node, training times can significantly increase since the dataset is huge. LÄS MER

  4. 3. Assessing blockchain technology for Transport Data Logger

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Björn Johansson; [2018]
    Nyckelord :blockchain; transport data logger; hyperledger; hyperledger fabric; byzantine fault tolerance; bft; supply chain; transport chain; permissioned; permissionless; documental truth; historical truth; immutability; security; log data; Technology and Engineering;

    Sammanfattning : A proof of concept permissioned blockchain system that holds data from the Transport Data Logger, TDL, was developed. Transport chain actors who hand off TDL-equipped goods between one another use the TDL app to upload a digital handoff containing their identities and log data from and signed by the TDL to a Hyperledger Fabric blockchain network.

  5. 4. A Multi-leader Approach to Byzantine Fault Tolerance : Achieving Higher Throughput Using Concurrent Consensus

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Muhammad Zeeshan Abid; [2015]
    Nyckelord :Byzantine Failures; Fault Tolerance; Performance; Reliability;

    Sammanfattning : Byzantine Fault Tolerant protocols are complicated and hard to implement.Today’s software industry is reluctant to adopt these protocols because of thehigh overhead of message exchange in the agreement phase and the high resourceconsumption necessary to tolerate faults (as 3 f + 1 replicas are required totolerate f faults).
