The paper "SCSA: Exploring the Synergistic Effects Between Spatial and Channel Attention" by Yunzhong Si et al. explores the synergy between spatial and channel attention mechanisms in deep learning for various downstream vision tasks. The authors propose a novel module called Spatial and Channel Synergistic Attention (SCSA), which consists of two main components: Shareable Multi-Semantic Spatial Attention (SMSA) and Progressive Channel-wise Self-Attention (PCSA). SMSA integrates multi-semantic information and uses a progressive compression strategy to inject discriminative spatial priors into PCSA's channel self-attention, guiding channel recalibration. PCSA leverages the self-attention mechanism to mitigate semantic disparities among different sub-features within SMSA. Extensive experiments on seven benchmark datasets, including ImageNet-1K, MSCOCO 2017, ADE20K, and others, demonstrate that SCSA outperforms existing attention mechanisms in terms of accuracy and generalization capabilities. The code and models are available at: https://github.com/HZAI-ZJNU/SCSA. The paper also includes detailed discussions on related work, methodological details, experimental results, and ablation studies, highlighting the effectiveness and robustness of SCSA in various visual tasks.The paper "SCSA: Exploring the Synergistic Effects Between Spatial and Channel Attention" by Yunzhong Si et al. explores the synergy between spatial and channel attention mechanisms in deep learning for various downstream vision tasks.
