Federated Learning
Federated Learning is a machine learning approach that enables model training across decentralized devices or servers holding local data samples, without exchanging the data itself. It allows multiple parties to collaboratively train a shared model while keeping their data private and on-premises, addressing privacy and data governance concerns. This technique is particularly useful in scenarios where data cannot be centralized due to regulatory, security, or logistical constraints.
Developers should learn Federated Learning when building applications that require privacy-preserving machine learning, such as in healthcare, finance, or mobile devices where user data cannot be shared. It's essential for use cases like training predictive models on sensitive data from multiple hospitals, improving keyboard suggestions on smartphones without uploading typing data, or enabling cross-organizational AI collaborations while complying with GDPR or HIPAA regulations.
