Query: Partitioned Variational Inference: A Framework for Probabilistic
  Federated Learning   The proliferation of computing devices has brought about an opportunity to
deploy machine learning models on new problem domains using previously
inaccessible data. Traditional algorithms for training such models often
require data to be stored on a single machine with compute performed by a
single node, making them unsuitable for decentralised training on multiple
devices. This deficiency has motivated the development of federated learning
algorithms, which allow multiple data owners to train collaboratively and use a
shared model whilst keeping local data private. However, many of these
algorithms focus on obtaining point estimates of model parameters, rather than
probabilistic estimates capable of capturing model uncertainty, which is
essential in many applications. Variational inference (VI) has become the
method of choice for fitting many modern probabilistic models. In this paper we
introduce partitioned variational inference (PVI), a general framework for
performing VI in the federated setting. We develop new supporting theory for
PVI, demonstrating a number of properties that make it an attractive choice for
practitioners; use PVI to unify a wealth of fragmented, yet related literature;
and provide empirical results that showcase the effectiveness of PVI in a
variety of federated settings.
