Communication Cost
Communication cost, the overhead associated with transmitting data in distributed computing and machine learning, is a critical bottleneck in many applications. Current research focuses on reducing this cost through techniques like model compression (e.g., using diffusion models or quantization), efficient aggregation strategies (e.g., hierarchical communication or aggregation before communication), and optimized communication protocols (e.g., event-triggered synchronization or all-to-all based gradient averaging). Addressing communication cost is crucial for enabling scalable and efficient distributed systems, particularly in resource-constrained environments like federated learning and large language model training, impacting both the feasibility and performance of these technologies.
