Can We Trust the Similarity Measurement in Federated Learning?

no code implementations20 Oct 2023 Zhilin Wang, Qin Hu, Xukai Zou

We first uncover the deficiencies of similarity metrics that high-dimensional local models, including benign and poisoned models, may be evaluated to have the same similarity while being significantly different in the parameter values.
