15. Language Processing:
Generate SQL from natural language.
Natural Language: Publish department
SQL Query: Select * from department
Natural Language: Show all student information of Section E, 40 batch,
CSE
SQL Query: Select * from CSE_students where batch = `40` AND section
= `E`

16. NLPTechnique:
1. One of the Machine Learning application is NLP
2. Two approach:
I. Supervised.
* Tag key-word work as training set
* YouTube Suggestion, Favorite list in messenger.
II. Unsupervised.
* No pre-training set.
* Clustering, Data analyzation, Google Search
