Abstract
A federal machine-learning system includes a global server and client devices. The server receives updates of weight factor dictionaries and factor strength vectors from the clients, and generates a globally updated weight factor dictionary and a globally updated factor strength vector. A client device selects a group of parameters from a global group of parameters, and trains a model using a dataset of the client device and the group of selected parameters. The client device sends to the server a client-updated weight factor dictionary and a client-updated factor strength vector. The client device receives the globally updated weight factor dictionary and the globally updated factor strength vector, and retrains the model using the dataset of the client device, the group of parameters selected by the client device, and the globally updated weight factor dictionary and the globally updated factor strength vector.
