Decentralised Semi-supervised Onboard Learning for Scene Classification in Low-Earth Orbit
Johan Östman, Pablo Gomez, Vinutha Magal Shreenath +1
Onboard machine learning on the latest satellite hardware offers the potential for significant savings in communication and operational costs. We showcase the training of a machine…
FedGT: Identification of Malicious Clients in Federated Learning with Secure Aggregation
Marvin Xhemrishi, Johan Östman, Antonia Wachter-Zeh +1
We propose FedGT, a novel framework for identifying malicious clients in federated learning with secure aggregation. Inspired by group testing, the framework leverages overlapping…
PAseos Simulates the Environment for Operating multiple Spacecraft
Pablo Gómez, Johan Östman, Vinutha Magal Shreenath +1
The next generation of spacecraft is anticipated to enable various new applications involving onboard processing, machine learning and decentralised operational scenarios. Even tho…
Decentralized Online Bandit Optimization on Directed Graphs with Regret Bounds
Johan Östman, Ather Gattami, Daniel Gillblad
We consider a decentralized multiplayer game, played over rounds, with a leader-follower hierarchy described by a directed acyclic graph. For each round, the graph structure di…
Efficient Node Selection in Private Personalized Decentralized Learning
Edvin Listo Zec, Johan Östman, Olof Mogren +1
Personalized decentralized learning is a promising paradigm for distributed learning, enabling each node to train a local model on its own data and collaborate with other nodes to…
