Practical Data Science and Applications

Fundamentals of programming with Python and Python libraries for data manipulation. This is a hands-on course with a substantial amount of project work. No prior knowledge of Python is needed, but a basic understanding of programming concepts (variables, types, functions, files, etc) as well as computer use skills are required.

Part I: We will cover principles of object-oriented and structured programming, data representation via Python data structures, and fundamental data manipulation in idiomatic Python. Then, we will examine Python libraries for scientific computing (numpy and scipy).

Part II: We will learn to work with basic software development technologies (version control, package installation, package publication) and interactive environments. A practical introduction to Jupyter, pandas, scikit-learn and matplotlib will be followed by students demonstrating their use on introductory data analysis tasks.

Part III: An introduction to high-performance computing techniques via Python, including dask and tensorflow will be given. Students will be asked to implement all stages of a scientific workflow, demonstrating the skills acquired in the previous stages of the course.

Research seminar/ Independent Study/Capstone project

This element of the program involves the combination of independent study by the students and attendance of research seminars in preparation for the selection and execution of a capstone project.  The latter will involve research and analysis of datasets based on concepts and tools learned by students in MLDS courses.  The results achieved by each project will be presented at the end of the academic year to the MLDS instructors in front of a public audience.  The duration of each presentation should be 20 minutes.  Some ideas for effective presentations are given in the Seminars/Project e-class module along with research papers which the students can use for independent study. 

The title and content of the capstone project is agreed upon between the student and a supervisor who is an MLDS instructor.  The ECE School needs to be notified of the project title and the supervisor.  Email a completed project assignment form to ece_secretary<at> for initial assignment.  If the title of the project changes, please email this form to the Department office.
