摘要： 前言 对于命名实体识别任务，基于神经网络的方法非常普遍。例如，Neural Architectures for Named Entity Recognition提出了一个使用word and character embeddings的BiLSTM-CRF命名实体识别模型。我将以本文中的模型为例来解释 阅读全文

摘要： PyTorch中，在反向传播前为什么要手动将梯度清零？ 原因在于，在PyTorch中，计算得到的梯度值会进行累加,而这样的好处，可以从内存消耗的角度来看。 在PyTorch中，multi-task任务一个标准的train from scratch流程为: for idx, data in enume 阅读全文
