MDENet: Multi-modal Dual-embedding Networks for Malware Open-set Recognition

no code implementations2 May 2023 Jingcai Guo, Yuanyuan Xu, Wenchao Xu, Yufeng Zhan, Yuxia Sun, Song Guo

Malware open-set recognition (MOSR) aims at jointly classifying malware samples from known families and detect the ones from novel unknown families, respectively.

DaFKD: Domain-Aware Federated Knowledge Distillation

no code implementations CVPR 2023 Haozhao Wang, Yichen Li, Wenchao Xu, Ruixuan Li, Yufeng Zhan, Zhigang Zeng

In this paper, we propose a new perspective that treats the local data in each client as a specific domain and design a novel domain knowledge aware federated distillation method, dubbed DaFKD, that can discern the importance of each model to the distillation sample, and thus is able to optimize the ensemble of soft predictions from diverse models.

On real structured controllability/stabilizability/stability radius: Complexity and unified rank-relaxation based methods

no code implementations4 Jan 2022 Yuan Zhang, Yuanqing Xia, Yufeng Zhan

This paper addresses the real structured controllability, stabilizability, and stability radii (RSCR, RSSZR, and RSSR, respectively) of linear systems, which involve determining the distance (in terms of matrix norms) between a (possibly large-scale) system and its nearest uncontrollable, unstabilizable, and unstable systems, respectively, with a prescribed affine structure.

Fast Subspace Identification Method Based on Containerised Cloud Workflow Processing System

no code implementations29 Dec 2021 Runze Gao, Yuanqing Xia, Guan Wang, Liwen Yang, Yufeng Zhan

Subspace identification (SID) has been widely used in system identification and control fields since it can estimate system models only relying on the input and output data by reliable numerical operations such as singular value decomposition (SVD).

TFDPM: Attack detection for cyber-physical systems with diffusion probabilistic models

no code implementations20 Dec 2021 Tijin Yan, Tong Zhou, Yufeng Zhan, Yuanqing Xia

With the development of AIoT, data-driven attack detection methods for cyber-physical systems (CPSs) have attracted lots of attention.

Total Unimodularity and Strongly Polynomial Solvability of Constrained Minimum Input Selections for Structural Controllability: an LP-based Method

no code implementations10 Aug 2021 Yuan Zhang, Yuanqing Xia, Yufeng Zhan

Subject to a certain condition on the prescribed input configurations that contains the dedicated input one as a special case, we demonstrate that the constraint matrices of these ILPs are totally unimodular.

ScoreGrad: Multivariate Probabilistic Time Series Forecasting with Continuous Energy-based Generative Models

1 code implementation18 Jun 2021 Tijin Yan, Hongwei Zhang, Tong Zhou, Yufeng Zhan, Yuanqing Xia

However, many existing works can not be widely used because of the constraints of functional form of generative models or the sensitivity to hyperparameters.
