| description | Hyperspectral image classification faces significant challenges due to the high dimensionality of spectral data and complex feature relationships between bands. To address the limitations of existing methods, we propose a novel hybrid attention network (ATN-Hybrid) based on a deterministic-probabilistic mechanism for hyperspectral image classification. The network employs a dual-branch structure: the deterministic branch generates stable feature weights through explicit channel mapping and normalization, while the probabilistic branch implements temperature-guided adaptive feature selection through a soft attention mechanism. Additionally, we design an adaptive feature fusion strategy with learnable fusion coefficients for dynamic feature optimization. Extensive experimental validation is conducted on four benchmark datasets: Indian Pines, Pavia University, Kennedy Space Center, and Salinas Valley. Experimental results demonstrate that ATN-Hybrid achieves superior performance compared with existing state-of-the-art methods, attaining overall accuracies of 96.01%, 95.23%, 97.37%, and 95.99% on the four datasets, respectively. The method shows particular advantages in both distinguishing classes with similar spectral features and handling limited training samples, achieving favorable results using only 3–9% of the data for training. The hybrid attention mechanism demonstrates strong generalization capabilities in both agricultural and urban scene classification while maintaining stable performance across different spatial resolutions and spectral characteristics. |
