Polo Club of Data Science
The latest version of this course is here.

This course will introduce you to broad classes of techniques and tools for analyzing and visualizing data at scale. It emphasizes on how to combine computation and visualization to perform effective analysis. We will cover methods from each side, and hybrid ones that combine the best of both worlds. Students will work in small teams to complete a research project exploring novel approaches for interactive data & visual analytics.

Piazza Discussion Forum

We will use Piazza for discussion (e.g., homework, project). Post your questions there, and the teaching staff and your fellow classmates will be able to help answer them quickly. You can also use Pizza to find project teammates.

T-square will only be used for submission of assignments and projects.

Grading

Late Submissions Policy

Homework (tentative)

Please note that while collaboration is allowed, individual collaborators *must* write up their own answers. All GT students must observe the honor code.

Project

Team project: 3-4 people. Description and grading policy (proposal + presentation, progress report, final report + presentation).

Dataset Ideas (may need API, or scraping)

Auditors

Auditors must first obtain instructor's permission of the instructor, then enroll in the course. The auditor must attend all lectures, and optionally complete the assignments.
