The coordinate attention block is another starting point for the present work. In our AttentionVoxelMoprh network, we introduce Dual Attention CNN Architecture by combining coordinate attention block and spatial attention block to further strengthen salient features and suppress useless information in the...
在第二个Decoder阶段将会结合之前的编码向量和目标时间序列的历史值来做最后的输出。在第二个阶段中的Attention机制会在时间维度上选取注意力点,为不同时间点的值来设定权重。因此最后的预测结果是基于时间和feature两个维度的attention机制。下面给出Encoder和Decoder的PyTorch定义,forward过程中每一步的维度都注释在语句...
