Bilstm-attention实现关系抽取 基于pytorch
WebThis changes the LSTM cell in the following way. First, the dimension of h_t ht will be changed from hidden_size to proj_size (dimensions of W_ {hi} W hi will be changed accordingly). Second, the output hidden state of each layer will be multiplied by a learnable projection matrix: h_t = W_ {hr}h_t ht = W hrht. WebPytorch is a dynamic neural network kit. Another example of a dynamic kit is Dynet (I mention this because working with Pytorch and Dynet is similar. If you see an example in Dynet, it will probably help you implement it in Pytorch). The opposite is the static tool kit, which includes Theano, Keras, TensorFlow, etc.
