Adaptive Gradient-Based Methods for a Broader Class of Optimization Problems under Performative Prediction

Hiroki Hamaguchi, Yuya Hikima, Hiroshi Sawada +1

The paper proposes a gradient-based optimization algorithm that estimates distribution shifts via finite differences, providing convergence guarantees for a wider range of loss fun…

FedPM: Federated Learning Using Second-order Optimization with Preconditioned Mixing of Local Parameters

Hiro Ishii, Kenta Niwa, Hiroshi Sawada +3

We propose Federated Preconditioned Mixing (FedPM), a novel Federated Learning (FL) method that leverages second-order optimization. Prior methods--such as LocalNewton, LTDA, and F…
