    While the Swin Transformer effectively reduces computational cost using window-based attention, it struggles to model global dependencies across windows. Prior work, such as the Refined Transformer, attempts to overcome this limitation by incorporating CBAM-style channel and spatial attention mechanisms. However, these sequential attention operations often introduce representational bias by overemphasizing specific features. To address this, we propose two key components: (1) the Efficient Head Self-Attention (EHSA) module, which dynamically calibrates the relative contribution of each attention head within a window, and (2) the Hierarchical Local-to-Global Spatial Attention (HLSA) module, which captures long-range interactions across windows in a hierarchical manner. By integrating these into a Swin-T backbone, our architecture improves both local detail modeling and global context aggregation. Experiments on ImageNet-1K and ImageNet100 demonstrate that our model surpasses the Refined Transformer and other window-based approaches in accuracy, while maintaining a comparable level of computational efficiency. These results validate the effectiveness of our design in enhancing local-global interactions within Vision Transformers.
