Datacamp class for master student - 5 days

The aim of this course is to learn data science by doing. All aspects of completing a data science pipeline will be covered, from exploratory data analysis (EDA), feature engineering, parameter optimization to advanced learning algorithms. You will also need to setup your own challenge!

Grade is a mix of your performance on the data challenge offered to the class as well as the challenge you will setup.

Each day you will have 50% of lectures and 50% of work on the competitive challenge using the RAMP website.

The slides used in some of the lectures are available here.

The course will be during the week from Dec 18 to Dec 22 in person.

On GitHub you have some of the teaching materials at: https://github.com/x-datascience-datacamp

You must have a GitHub account to complete the course.

We will be using many Python packages in this course such as pandas, sklearn, and matplotlib, and they can all be downloaded and installed using a package-management system. We recommend you to use mamba but you will be fine if you already have conda installed in your computer.

NB: Windows users should be sure to closely follow the instructions for installing mamba and conda, since many common problems come from not having properly setup the PATH variable for the system.
