  Distributed Artificial Intelligence is attracting interest day by day. In
this paper, the authors introduce an innovative methodology for distributed
learning of Particle Swarm Optimization-based Fuzzy Cognitive Maps in a
privacy-preserving way. The authors design a training scheme for collaborative
FCM learning that offers data privacy compliant with the current regulation.
This method is applied to a cancer detection problem, proving that the
performance of the model is improved by the Federated Learning process, and
obtaining similar results to the ones that can be found in the literature.
