Expert Load

Expert load, the distribution of computational workload across different components of a model, is a critical challenge in large-scale machine learning, particularly within Mixture-of-Experts (MoE) architectures. Current research focuses on developing efficient load balancing strategies, including novel routing algorithms and loss functions that minimize computational overhead without sacrificing model accuracy, often employing techniques like null experts or bias adjustments to achieve more even distribution. Addressing expert load imbalance is crucial for optimizing the performance and scalability of MoE models, impacting both the efficiency of training large language models and the practical deployment of human-AI collaborative systems where minimizing expert intervention is paramount.
