Task-Aware Machine Unlearning and Its Application in Load Forecasting

1 code implementation28 Aug 2023 Wangkun Xu, Fei Teng

To balance between unlearning completeness and model performance, a performance-aware algorithm is proposed by evaluating the sensitivity of local model parameter change using influence function and sample re-weighting.

Blending Data and Physics Against False Data Injection Attack: An Event-Triggered Moving Target Defence Approach

1 code implementation27 Apr 2022 Wangkun Xu, Martin Higgins, Jianhong Wang, Imad M. Jaimoukha, Fei Teng

However, the uncontrollable false positive rate of the data-driven detector and the extra cost of frequent MTD usage limit their wide applications.

Cyber-Physical Risk Assessment for False Data Injection Attacks Considering Moving Target Defences

no code implementations22 Feb 2022 Martin Higgins, Wangkun Xu, Fei Teng, Thomas Parisini

In this paper, we examine the factors that influence the success of false data injection (FDI) attacks in the context of both cyber and physical styles of reinforcement.

Robust Moving Target Defence Against False Data Injection Attacks in Power Grids

1 code implementation11 Nov 2021 Wangkun Xu, Imad M. Jaimoukha, Fei Teng

Recently, moving target defence (MTD) has been proposed to thwart false data injection (FDI) attacks in power system state estimation by proactively triggering the distributed flexible AC transmission system (D-FACTS) devices.

Multi-Agent Reinforcement Learning for Active Voltage Control on Power Distribution Networks

1 code implementation NeurIPS 2021 Jianhong Wang, Wangkun Xu, Yunjie Gu, Wenbin Song, Tim C. Green

This paper presents a problem in power networks that creates an exciting and yet challenging real-world scenario for application of multi-agent reinforcement learning (MARL).

A Deep Learning based Detection Method for Combined Integrity-Availability Cyber Attacks in Power System

no code implementations3 Nov 2020 Wangkun Xu, Fei Teng

As one of the largest and most complex systems on earth, power grid (PG) operation and control have stepped forward as a compound analysis on both physical and cyber layers which makes it vulnerable to assaults from economic and security considerations.
