Self-attention和cnn
WebMar 13, 2024 · CNN 用于图像识别，它通过使用卷积层（convolutional layer）和池化层（pooling layer）来提取图像的特征。 Transformer 模型是一种注意力机制的深度学习模型，用于处理序列数据，如自然语言处理任务。 在实际应用中，CNN 和 Transformer 模型可以结合使用，以改进模型的 ... Web考虑到卷积和Self-Attention的不同和互补性质，通过集成这些模块，存在从两种范式中受益的潜在可能性。先前的工作从几个不同的角度探讨了Self-Attention和卷积的结合。 早期的研究，如SENet、CBAM，表明Self-Attention可以作为卷积模块的增强。
