This is an annotated version of the basic word2vec script. The code is based on the Word2Vec tutorial provided by Tensorflow: https://www.tensorflow.org/tutorials/word2vec.
History
Word2vec is a neural network
word2vec_basic_algolit.py
The structure of the annotated word2vec script is the following:
- Step 1: Download data. (optional)
- Algolit step 1: read data from plain text file
- Step 2: Create a dictionary and replace rare words with UNK token.
- Algolit extension: write the dictionary to dictionary.txt
- Step 3: Function to generate a training batch for the skip-gram model.
- Step 4: Build and train a skip-gram model.
- Algolit extension: select your own set of test words, using the dictionary.txt
- Step 5: Begin training.
- Algolit extension: write training log to logfile.txt
- Step 6: Visualize the embeddings.
Source
The script provides an option to download a dataset from
