50.038 Computational Data Science

Course Description

This course provides students the necessary background and experience in data science technology and concepts. Students will gain experience with tackling a complete data science project, from data gathering and preprocessing to data analysis through machine learning tools. Students will learn to apply fundamental concepts in machine learning to data storage and distributed processing as a foundation for their project.
