Description: The Joint Learning Protocol is a set of rules governing the collaborative training process in federated learning. This approach allows multiple devices or entities to collaborate in training artificial intelligence models without the need to share sensitive data. Instead of centralizing information, each participant trains a model locally using their own data and then sends only the updated model parameters to a central server. This server aggregates updates from all local models to create an improved global model. This method not only preserves data privacy but also reduces the need to transfer large volumes of information, which can be costly and slow. Additionally, the Joint Learning Protocol encourages collaboration among different organizations, allowing them to mutually benefit from the knowledge gained without compromising the security of their data. In summary, this protocol is essential for the development of machine learning applications in environments where data privacy and security are paramount, particularly in sectors such as healthcare, finance, and across various applications and devices.
