Benchmarking Results for MPI-based federated learning
Please visit the following link to check the latest benchmark experimental results: https://app.wandb.ai/automl/fedml/reports/FedML-Benchmark-Experimental-Results--VmlldzoxODE2NTU FedML white paper (https://arxiv.org/pdf/2007.13518.pdf) also summarizes the dataset list and related benchmarks. We refer the hyper-parameters and reproduce results from many top-tier ML conferences. Please check details of our reference hyperparameters as follows.
