HSL-CFS: Hybrid stacked learning with cooperative feature selection for cyberattack detection in smart grids
摘要
Abstract
An effective method for detecting cyberattacks is essential to the security of smart grids (SGs). In SGs
data from both cyber and physical domains can support attack detection. However
existing works insufficiently consider the heterogeneity
high dimensionality
and cross-domain correlations of multi-source data
affecting model generalization
stability
and detection accuracy. To address these limitations
this paper proposes a hybrid stacked learning method with cooperative feature selection (HSL-CFS). First
a cooperative feature selection approach is proposed for feature extraction from multi-source heterogeneous data. An embedded method with adaptive threshold adjustment and a wrapper method with dynamic bidirectional search extract key features from complementary perspectives
and their feature sets are merged via set union to output representative features. Second
a hybrid stacked model combining Extreme Random Trees (ET) and an improved Convolutional Neural Network (CNN) is proposed. The CNN is enhanced with Euclidean-norm regularization (L2 regularization) and Squeeze-and-Excitation (SE) block attention mechanism to mitigate overfitting and recalibrate channel responses. Furthermore
probability alignment calibrates base classifier outputs before stacking
enabling better capture of complementary patterns in SGs cyber-physical data. Experimental results show that HSL-CFS selects fewer features and achieves enhanced stability
generalization and accuracy
outperforming existing methods on the selected dataset.
