Fusion of PCA and Segmented-PCA Domain Multiscale 2-D-SSA for Effective Spectral-Spatial Feature Extraction and Data Classification in Hyperspectral Imagery

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2022
As hyperspectral imagery (HSI) contains rich spectral and spatial information, a novel principal component analysis (PCA) and segmented-PCA (SPCA)-based multiscale 2-D-singular spectrum analysis (2-D-SSA) fusion method is proposed for joint spectral ...

Efficient Cyber Attack Detection in Industrial Control Systems Using Lightweight Neural Networks and PCA

open access: yesIEEE Transactions on Dependable and Secure Computing, 2021
Industrial control systems (ICSs) are widely used and vital to industry and society. Their failure can have severe impact on both the economy and human life. Hence, these systems have become an attractive target for physical and cyber attacks alike.
