Build the basic language models in Python.
From spam filters to ChatGPT, computer and AI systems have to work with language models all the time. In this course, you will learn how to build and work with the most common language models in data science, including bag-of-words, tf-idf, and word embeddings. Learn the basic skills you need before working with more advanced AI language models.


* Create common language models

* Measure similarity between words

* Determine important words in documents


### Notes on Prerequisites
This course requires a basic knowledge of Python. If you are a beginner, start with [Learn Python for Data Science](https://www.codecademy.com/learn/paths/learn-python-for-data-science) or learn to build language models from scratch in our [Build Chatbots with Python](https://www.codecademy.com/learn/paths/build-chatbots-with-python) Skill Path.
