About The Project

During the session we will cover how to scrape data from websites using a practical example. We will then use the data to model a linear regression algorithm to help predict the price of a car given several attributes. The session will flow as follows:

• A background on what machine learning is

• How linear regression works

• Web scraping using a headless browser (puppeteer)

• Concurrency when scraping to speed up the process.

• Exporting the data

• Importing the data in our Jupyter notebook

• Data cleaning

• Data exploration

• Data modeling

• Challenge
