Explore federated learning, a revolutionary technology for training machine learning models across distributed devices while preserving privacy. Discover how this approach allows models to learn from decentralized data without sensitive information leaving users' devices. Gain insights into Google's production deployment of federated learning and learn how TensorFlow Federated enables researchers to simulate this technique on their own datasets. Delve into the federated learning workflow, comparing it to traditional distributed learning, and understand its applications in language modeling and handling new words. This 41-minute conference talk from Google I/O'19, presented by Daniel Ramage and Emily Glanz, covers key concepts such as secure aggregation, federated computation, and the distinctions between federated and decentralized computing.
