Description: Shared learning is a collaborative approach within the framework of federated learning, where multiple clients or devices contribute to the training of an artificial intelligence model without the need to share their local data. This method allows models to be trained in a decentralized manner, preserving data privacy and minimizing the risk of sensitive information leaks. Instead of sending data to a central server, each client trains the model locally and only shares the updated parameters, such as model weights, with a central server that aggregates them to improve the global model. This approach not only optimizes data usage but also allows the model to benefit from a diversity of data, which can result in improved performance and greater generalization. Shared learning is particularly relevant in contexts where data privacy and security are paramount, such as in healthcare, finance, and mobile devices. Additionally, it fosters collaboration among different entities, allowing organizations with valuable but sensitive data to contribute to the development of artificial intelligence models without compromising the confidentiality of their information.
