Weekly faculty research seminar. Individual HDSI colloquia and distinguished lecturers may be included at the discretion of the instructor. May be taken for credit up to twenty-four times. Prerequisites: none.
DSC 294. Research Rotation (4)
Research rotations provide the opportunity for first-year PhD students to obtain research experience in data analysis under the guidance of HDSI affiliated faculty members. Through the rotations, students can identify a faculty member under whose supervision their dissertation research will be completed. Each research rotation is quarter-long; working with a HDSI faculty member and students are required to complete three separate rotations. Each student is required to take the course three times with at least two different instructors. Prerequisites: none. Only first-year PhD students are eligible.
DSC 295. Academia Survival Skills (1)
Basic skills necessary to succeed as a researcher in data science including scripting, cloud computing skills, fellowship proposal preparation, CV preparation, writing reviews, preparing posters, etc. Prerequisites: none.
DSC 298R. Graduate Capstone in Data Science (4)
Following the life cycle of a data science project, students apply advanced data science knowledge and techniques to a specific domain. Cleaning and structuring data for hypothesis generation and data analysis; creating a scalable big date pipeline from data ingestion and exploration, to modeling and evaluation; building machine learning models and evaluating insights; communicating finding through visualizations and reports; fully considering ethical implications throughout. Prerequisites: DSC 208R, DSC 255R, and DSC 256R. Restricted to students within the DS77 degree program. All other students with graduate standing may be considered as space permits.
DSC 299. Graduate Research (1–16)
Graduate research. May be taken for credit up to twenty-four times. Prerequisites: none.
DSC 500. Teaching Assistantship (2 or 4)
A course in which teaching assistants are aided in learning proper teaching methods by means of supervision of their work by the faculty: handling of discussions, preparation and grading of examinations and other written exercises, and student relations. Number of units for credit depends on number of hours devoted to class or section assistance. May be taken for credit up to seventy-two units. Prerequisites: DSC 500 is for selected teaching assistants only; therefore, consent of instructor is required.
DSC 599. Teaching Methods in Data Science (2)
Training in teaching methods in the field of data science. This course examines theoretical and practical communication and teaching techniques particularly appropriate to data science. Prerequisites: Consent of faculty required. Only graduate students who are TAing for the first time in the data science program are eligible to enroll.
