Natural Language Processing Tutorial

Tutorial in Chinese can be found in mofanpy.com.

This repo includes many simple implementations of models in Neural Language Processing (NLP).

All code implementations in this tutorial are organized as following:

1. Search Engine

• TF-IDF numpy / TF-IDF skearn

2. Understand Word (W2V)

• Continuous Bag of Words (CBOW)
• Skip-Gram

3. Understand Sentence (Seq2Seq)

• seq2seq
• CNN language model

4. All about Attention

• seq2seq with attention
• Transformer

5. Pretrained Models

• ELMo
• GPT
• BERT

Thanks for the contribution made by @W1Fl with a simplified keras codes in simple_realize
