    Privacy-preserving federated learning framework with dynamic weight aggregation by Zuobin YING, Yichen FANG, Yiwen ZHANG

    Published 2022-10-01
    “…There are two problems with the privacy-preserving federal learning framework under an unreliable central server.① A fixed weight, typically the size of each participant’s dataset, is used when aggregating distributed learning models on the central server.However, different participants have non-independent and homogeneously distributed data, then setting fixed aggregation weights would prevent the global model from achieving optimal utility.② Existing frameworks are built on the assumption that the central server is honest, and do not consider the problem of data privacy leakage of participants due to the untrustworthiness of the central server.To address the above issues, based on the popular DP-FedAvg algorithm, a privacy-preserving federated learning DP-DFL algorithm for dynamic weight aggregation under a non-trusted central server was proposed which set a dynamic model aggregation weight.The proposed algorithm learned the model aggregation weight in federated learning directly from the data of different participants, and thus it is applicable to non-independent homogeneously distributed data environment.In addition, the privacy of model parameters was protected using noise in the local model privacy protection phase, which satisfied the untrustworthy central server setting and thus reduced the risk of privacy leakage in the upload of model parameters from local participants.Experiments on dataset CIFAR-10 demonstrate that the DP-DFL algorithm not only provides local privacy guarantees, but also achieves higher accuracy rates with an average accuracy improvement of 2.09% compared to the DP-FedAvg algorithm models.…”

    Sensitivity Study of WRF Parameterization Schemes and Initial Fields on Rainstorm Simulation in Minjiang River Basin by LIN Sinuo, ZHANG Yinchi, SUN Shao, GUAN Xiaojun, JIANG Caiying, GAO Lu

    Published 2023-01-01
    “…,weather research and forecasting (WRF) model,16 sets of microphysical processes and cumulus convection parameterization schemes are cross-combined to simulate the sensitivity of a continuous rainstorm process in the Minjiang River Basin from May 17 to 24,2021.The results show that the WRF model can reproduce the spatio-temporal distribution characteristics of this rainfall process,but it significantly overestimates the intensity and extent of the storm center,with the overall better performance of EXP9 (Lin-NT combination).For the mass sensitivity test of initial fields,the simulation results based on the optimal combination of parameterization schemes reveal that the fifth-generation atmospheric reanalysis of the European Center for Medium-Range Weather Forecasts (ERA5) has a sound effect for all magnitudes of rainfalls.Meanwhile,it best matches the spatio-temporal characteristics of the observed data,followed by global data assimilation system/final operational global analysis (GDAS/FNL),while climate forecast system operational analysis (CFS) is the worst.This study can provide methodological references for improving the accuracy of extreme rainfall simulation and forecasting.…”
