Word To Vector Demo

This repository includes some demo word2vec models.

Note: The project refers to 动手学深度学习

Datasets:

• dataset1: text8
• dataset2: ptb

Models:

• model1 (DONE): Continuous-Bag-Of-Words with Hierarchical-Softmax
• model2 (DONE): Continuous-Bag-Of-Words with Negative-Sampling
• model3 (DONE): Skip-Gram with Hierarchical-Softmax
• model4 (DONE): Skip-Gram with Negative-Sampling
• model5 (TODO): FastText
• model6 (TODO): Glove

Data Process

# download dataset text8
PYTHONPATH=. python dataprocess/process.py --dataset_name text8
# download dataset ptb
PYTHONPATH=. python dataprocess/process.py --dataset_name ptb

Main Process

• for train

PYTHONPATH=. python main.py --mode train

• for predict

PYTHONPATH=. python main.py --mode predict

You can change the config either in the command line or in the file utils/parser.py
