Data is at the core of nearly every business decision. This joint degree with École Polytechnique, will provide students the tools needed to solve real problems, teaching them to ask the “right” questions (both from a Machine Learning and business perspective) and to use the appropriate mathematical and IT tools to answer them.

Students will be equipped to shift seamlessly from data to knowledge, from knowledge to strategic decision-making, and from strategic decision-making to operational business implementations. With the first year spent learning the technical skills at a world-class engineering school, combined with a practical application in the second year at HEC Paris, students will master how to leverage data in a business context. 

The teaching in the first year of the MSc data science for business focuses primarily on the foundation skills of Machine Learning and Deep Learning : statistics, probabilities, linear algebra, coding in R and Python…

Students will learn how to perform a complete data analysis, from data manipulation, exploration, and visualization to analysis with powerful machine learning methods and to communicate and deploy their solution.

For further information about the program at École Polytechnique, see their website.

Students can also benefit from refresher courses in probability, statistics and the mathematical foundations of data science.


  • Statistics
  • Regression
  • Machine Learning I and II
  • Deep Learning and Optimization
  • Database Management

In the Digital Age, everything has become information: data from social media, email exchanges, consumption habits, GPS data, bank transactions… All kinds of organizations are converting this vast amount of information into strategic resources. How should these data be stored? How can they be used? These questions impact the profit contributions of many functions within companies (marketing, sales, logistics, risk management) and, therefore, must be addressed.

HEC Paris and École Polytechnique, 2 globally-recognized institutions, have united forces to create a joint degree specifically aimed at providing students with strong skills in both Data Science and Business. This 2-year MSc program has been designed to combine high-level expertise in the engineering field, to train students in data sciences, with proficiency in the business field, to form data managers capable of taking strategic decisions based on data resources.

Profiles specialized in data science are in such high demand that often companies recruit students even before they graduate.  This degree will give you an invaluable asset so that you may become a key stakeholder in the digital transformation and evolve successfully in your business career.
