Projecting conflicting gradients
WebThis problem is addressed by using a method called projecting conflicting gradient (PCGrad)[23], which project’s the gradient of one task onto the nor- mal plane of the other task. In order to overcome the limitations of traditional MTL, GradNorm, and PCGrad, a unified architecture has been created taking advan- tage of both GradNorm and PCGrad. WebNov 22, 2024 · If gradient projection and deconfliction are performed on two gradients with excessive differences, the deconfliction will fail briefly (the deconflicted gradient will be towards the strong gradient node, violating the fairness principle). It can be effectively avoided by stratifying the nodes with similar characteristics for deconfliction.

WebWe identify a set of three conditions of the multi-task optimization landscape that cause detrimental gradient interference, and develop a simple yet general approach, projecting conflicting gradients (PCGrad), for avoiding such interference between task gradients. WebApr 30, 2024 · Fairness has emerged as a critical problem in federated learning (FL). In this work, we identify a cause of unfairness in FL -- conflicting gradients with large differences in the magnitudes. To address this issue, we propose the federated fair averaging (FedFV) algorithm to mitigate potential conflicts among clients before averaging their gradients. …
WebJun 16, 2024 · The uncertainty of sub-models is modeled to design optimization priorities, resulting in better average performance. Besides, we propose an aggregation method based on the gradients projection. As the conflicting gradients are projected to avoid mutual interference, the generic optimal direction for all sub-models is achieved.
