2. IPCADP-Equalizer: An Improved Multibalance Privacy Preservation Scheme against Backdoor Attacks in Federated Learning.

Abstract

Although there are some protection mechanisms in federated learning, its training process is still vulnerable to some powerful attacks, such as invisible backdoor attacks. Existing research work focuses more on how to prevent attacks in distributed training scenarios and improve the security of the FL training process, but it lacks consideration of utility and robustness, especially when the learning model of FL suffers from stealth backdoor attacks. This paper proposes an improved FL defense scheme IPCADP based on user-level differential privacy and variational autoencoders technology. The scheme can control and protect the privacy attribute of the image and can also eliminate the triggers that exist in the poisoned image. The experimental results show that compared with some existing defense schemes, IPCADP can defend against invisible backdoor attacks and improve the classification accuracy of the main task, while mitigating the impact of attacks on model robustness and stability. To a certain extent, the balance and unity of security, utility, and robustness are realized. [ABSTRACT FROM AUTHOR]

15. Supply Chain Coordination with Market Scale and Price Sensitivity Coefficient Disruptions under Nonlinear Demand Function

Abstract

This paper studies the coordination problem of a supply chain with one supplier and one retailer under demand disruption. When the market scale and price-sensitive coefficient are disrupted in the planning horizon, where price-demand relationship is nonlinear, the optimal emergency strategies about adjusting price and production quantity is proposed under the centralized model. For the decentralized model, it is proved that the supply chain can be fully coordinated by adjusting the revenue sharing contract when disruption occurs. Finally, a numerical analysis is given to illustrate the analysis approach.
