Weight Aggregation

Weight aggregation in machine learning focuses on combining model parameters or predictions from multiple sources to improve overall performance and robustness. Current research emphasizes developing adaptive weighting schemes that account for data heterogeneity, client reliability, and communication constraints, often employing techniques like personalized weighting, graph-based aggregation, or reinforcement learning to optimize the aggregation process. These advancements are crucial for improving the efficiency and fairness of federated learning, enabling collaborative model training while preserving data privacy and mitigating the impact of noisy or malicious data sources in various applications, including healthcare and robotics.
