Abstract
A system may share updates to a machine learning model between a first device and a second device. The first device may update parameters of a model operating on the first device in response to processing input data. The first device may generate model update data based on the updated parameters, and send the model update data to the second device. The first and second devices may agree on one or more protocols for generating the model update data to obscure details of the model, and/or reduce a communication cost of sending the model update data (e.g., relative to a size of the model). The second device may aggregate model update data (e.g., from multiple devices), determine second model update data, and send the second model update data to the first device. The first device may update its own model based on the second model update data.
