06.06.2018 · nn.Embedding holds a Tensor of dimension (vocab_size, vector_size), i.e. of the size of the vocabulary x the dimension of each vector embedding, and a method that does the lookup.. When you create an embedding layer, the Tensor is initialised randomly. It is only when you train it when this similarity between similar words should appear.
