Communication efficiency

Definition

Communication efficiency refers to the effectiveness with which information is exchanged within a system, particularly focusing on reducing the amount of data transmitted while preserving the accuracy and relevance of that data. This concept is crucial in scenarios where bandwidth is limited, such as in distributed systems, as it helps ensure faster processing and lower latency during communication. In the realm of federated learning and privacy-preserving deep learning, enhancing communication efficiency means optimizing the exchange of model updates or data between devices while safeguarding user privacy.
