CS 5024 Ethics and Professionalism in Computer (Data) Science

Fall, 2020
Instructor: Chang-Tien Lu
Meeting Time: Monday 4:00-6:45 PM
Office: NVC 312
Office Hour: Tuesday 11AM-noon, Thursday 4-5PM, or by appointment

Course Synopsis: As computing, data science, and machine learning technologies become more pervasive, we must grapple with the ethical implications and consequences of algorithmic decision making. This is an opportune time to be studying ethical issues in data science because seldom a week goes by without an egregious instance of ethical violations and abuse by Silicon Valley companies coming to light. This course will cover frameworks to help you study ethical issues in data science, case studies of current happenings, and ideas on practicing professionalism in data science. As in similar thorny issues, there is sometimes no right or wrong answer and this course will help you reason about the underlying issues better.

Topics covered include: privacy, disclosure, and security implications; confidentiality and declassification of data; record linkage algorithms; data uniqueness and profiling; privacy-preserving data mining; unintended consequences of data mining; ethical boundaries in conducting large scale studies and making inferences; responsible behavior as a data scientist; case studies and critical analysis of scenarios from science, engineering, social media, law, business, humanities, and other practical contexts.

Project Report (Due 12/14, 4PM)


Evaluation:

20% graduate school required reading and quizzes
30% discussion participation on Canvas
15% in-class research presentation
35% final project (10%: final presentation, final report: 25%)
5% in-class discussion and participation

Online class participation: 

For each week, online class participation is scored based on the number of “substantial interactions” (defined below) on Canvas pertaining to that week’s material. A ‘week” here is defined as beginning from Monday 7pm of week x (i.e., just after class) to Monday 8am of week x+1. Students are expected to discuss week x+1’s material on the Discussion board in Canvas. Since this is an evaluative component, the instructor will not participate in the online Canvas discussion. If you are the first person to contribute to the discussion, please begin a new thread for that week’s discussion and others should add to the same thread (i.e., not open a new thread). You can interact anytime during that week (note the definition of week above). The first scored week runs from Aug 24 to Aug 31.

Interactions should be substantial, not superficial. A superficial interaction is one that simply agrees with that week’s material, regurgitates or summarizes content, or otherwise appears like an AI could have done it. A substantial interaction is one for which notable thought and effort has been put in. It can take various forms, e.g., i) it takes a stance or contributes an opinion or judges the week’s material either in a positive or negative light with supporting information, ii) it identifies external URLs, papers, examples, current happenings, references related to the week’s material and argues for their relevance, or iii) builds upon another contributor’s interaction in a substantial manner.

No judgment is being made on the stances you take – you are merely evaluated on your ability to reason about ethical and professional issues and provide evidence for your opinions. For instance, n-1 students can agree with a paper’s view and the nth student might disagree. The n-1 students might think some idea is risky but the nth student might view that the risks are worth the rewards, and as long as everybody argues diligently, they are given equal credit.

Scoring happens every week on a scale of 0-5. Scores for all weeks are added together. The final score is then scaled to meet the 40% online class participation above. An absence of participation for a week will constitute as a zero for that week.

In-class presentation: 

Students should sign-up one presentations to present that week’s reading material + discussions during the class session from 5:20-6:45pm. A Google spreadsheet for this purpose is at: https://tinyurl.com/cs5024signups.

Final project:

The final project is intended to be done in groups of 2-3 people. Students must choose a topic that is related to current happenings and that has not been discussed in class or that will not be discussed in class in the future, per the schedule. The project report must ideally involve a discussion of the ethical considerations, some data analysis and some recommendations. 

Disabilities:

Any student that is in need of special accommodations due to a disability, as recognized by the Americans with Disabilities Act, should contact the Services for Students with Disabilities (SSD) in the Dean of Students Office. Students with disabilities are responsible for self-identification.  To be eligible for services, documentation of the disability from a qualified professional must be presented to SSD upon request. Academic adjustments may include, but are not limited to: priority registration, auxiliary aids, program and course adjustment, exam modifications, oral or sign language interpreters, cassette taping of text/materials, note takers/readers, or assistive technology.

If you need adaptation or accommodations because of a disability (learning disability, attention deficit disorder, psychological, physical, etc.), if you have emergency medical information to share with me, or if you need special arrangements in case the building must be evacuated, please make an appointment with me as soon as possible. If you need captioning for videos, please let me know no later than two weeks in advance of date on syllabus for reviewing.
