| Pseudocode | Yes | Algorithm 1 Fed Opt framework |
| Open Source Code | Yes | We provide open-source implementations of all simulations in Tensor Flow Federated [4]2. 2https://github.com/google-research/federated/tree/f4e26c1b9b47ac320e520a8b9943ea2c5324b8c2/ large_cohort |
| Open Datasets | Yes | We use four datasets: CIFAR-100 [35], EMNIST [13], Shakespeare [8], and Stack Overflow [3]. |
| Dataset Splits | Yes | We tune learning rates for all algorithms and models using a held-out validation set: We perform T = 1500 rounds of training with M = 50, E = 1 for each algorithm and model, varying ηc, ηs over {10i | 3 i 1} and select the values that maximize the average validation performance over 5 random trials. |
| Hardware Specification | No | All experiments were conducted using clusters of multi-core CPUs, though our results are independent of wall-clock time and amount of compute resources. (This is too general; no specific CPU models or detailed cluster specs are provided). |
| Software Dependencies | No | We provide open-source implementations of all simulations in Tensor Flow Federated [4]2. (A version number for TensorFlow Federated or other libraries is not specified). |
| Experiment Setup | Yes | We set pk to be the number of examples in client k s dataset. We tune learning rates for all algorithms and models using a held-out validation set: We perform T = 1500 rounds of training with M = 50, E = 1 for each algorithm and model, varying ηc, ηs over {10i | 3 i 1} and select the values that maximize the average validation performance over 5 random trials. All other hyperparameters (such as momentum) are fixed. |
