• In this example, we would like to show how to use hsigmoid to training word embedding for large vocabulary.

• Please refer to this example provided by @reyoung. Note that this example is not for word embedding training exactly. You‘d better learn and then modify it.

• The example must include the training and the predicting process.

• Please pull your codes and docs into the word_embedding directory.

• In future, we may add more configuration for models with a large vocabulary.
