Two new research papers address the challenge of Byzantine attacks in Federated Learning (FL). The first paper introduces Projected Dimensionality Reduction (PDR), a framework designed to accelerate robust aggregation by compressing gradients into a smaller subspace, thereby reducing computational overhead without significantly impacting accuracy. The second paper proposes a novel optimization problem that treats aggregation weights as learnable parameters, allowing them to be jointly optimized with the global model for improved Byzantine resilience, especially in heterogeneous data scenarios.
