FedAegis: Edge-Based Byzantine-Robust Federated Learning for Heterogeneous Data

2022 IEEE GLOBAL COMMUNICATIONS CONFERENCE (GLOBECOM 2022), pp. 3005–3010.

By: F. Zhou n, R. Yu n, Z. Li n, H. Gu n & X. Wang n

Contributors: F. Zhou n, R. Yu n, Z. Li n, H. Gu n & X. Wang n

author keywords: Federated learning; edge computing; data heterogeneity; Byzantine robustness; distributionally robust optimization
TL;DR: Experiments show that the proposed FedAegis algorithm can achieve convergence and high accuracy under heterogeneous data and various attack scenarios, while state-of-the-art defenses and robustness mechanisms are non-converging or have reduced average and/or worst-case accuracy.

Why Riding the Lightning? Equilibrium Analysis for Payment Hub Pricing

IEEE INTERNATIONAL CONFERENCE ON COMMUNICATIONS (ICC 2022), pp. 5409–5414.

By: X. Wang n, H. Gu n, Z. Li n, F. Zhou n, R. Yu n & D. Yang*

Event: IEEE

author keywords: Payment channel network; game theory; price-setting competition; Bertrand competition
TL;DR: This paper applies equilibrium analysis to the price-setting game between two payment hubs in the PCN with limited channel capacities and partial overlap demand and analyzes existence of pure Nash Equilibriums (NEs) and bounds on the equilibrium revenue under various cases, and proposes an algorithm to find all pure NEs.
