The objective of this collaboration is to investigate the efficient distributed computation of generative adversarial networks (GANs) over a set of client devices. In particular, we will study the implementation of GANs in the setup of federated learning, where a server is leveraged as a central point for model synchronization.
In this model, the client data can remain on their devices, increasing privacy w.r.t. approaches that require the collection of all the data on a single location. Several angles are of interest in this collaboration:
(i) the fault tolerance aspect as not been studied in a constructive way, which leaves space for algorithms allowing robust learning.
(ii) The training of GANs is data intensive, as well as compute-intensive; the computation-communication trade-off that arise in this approach is yet to be understood, for an accurate comparison with central, or fully decentralized approaches (such as gossip-based ones for instance).
(iii) The intrinsic difference of GANs w.r.t. regular deep learning models, when it comes to distributed computation, is to be fully qualified for efficient proposals.
