网上资料说造成这个错误的原因是 keras 版本不对,在 mask-rcnn 仓库文件中的 requirement.txt 中提到要求安装的keras>=2.0.8,如下所示: 而load_weights_from_hdf5_group_by_name只在 keras2.0.8 的版本中出现,不会出现在最新的 keras 版本中出现。我查看了下当前安装的 keras 版本,是2.2.0,按照建议,将其更...

A similar trick in RNN training is called truncated backpropagation through time. We feed the model a very long sequence, but backpropagate only over part of it. The first part of the sequence, for which no gradients are computed, still influences the values of the hidden states in the par...

C. 并行的卷积递归神经网络CRNN 除了上面提到的预处理方法,我们还采用混合深度学习模型对情绪状态进行分类,称为“并行卷积循环神经网络”。 该模型是两种深度学习结构的组合。 它结合了CNN和RNN分别提取空间和时间特征的强大能力。CNN 单元用于挖掘跨通道相关性并从 2D 帧中提取特征。精细 RNN 结构“Long Short-Term...
