Training at the edge has also become attractive for privacy protection and for reducing communication costs tied to sending raw data to the cloud. These drivers motivate a DML-at-edge paradigm, while practical deployment must address limited, heterogeneous hardware, high communication overhead, and constraints that prevent effective on-device training on low-end devices.","Distributed machine learning on Edge computing  \nsystems  \nDi Wu  \nA thesis submitted for the degree of PhD  \nat the  \nUniversity of St Andrews  \n2024  \nFull metadata for this thesis is available in St Andrews Research Repository at:  \n[https://research-repository.st-andrews.ac.uk/](https://research-repository.st-andrews.ac.uk/)  \n[Identifier to use to cite or link to this thesis:](Identifier to use to cite or link to this thesis:)[ ](Identifier to use to cite or link to this thesis:)DOI: [https://doi.org/10.17630/sta/1164](https://doi.org/10.17630/sta/1164)  \nThis item is protected by original copyright  \nThis item is licensed under a Creative Commons Licence  \n[https://creativecommons.org/licenses/by-nc/4.0/](https://creativecommons.org/licenses/by-nc/4.0/)  \nCandidate's declaration  \nI, Di Wu, do hereby certify that this thesis, submitted for the degree of PhD, which is approximately 55,000 words in length, has been written by me, and that it is the record of work carried out by me, or principally by myself in collaboration with others as acknowledged, and that it has not been submitted in any previous application for any degree.
