Course Description

The rapid advance in artificial intelligence (AI) has opened up new possibilities of using AI to tackle the most challenging societal problems today. This course brings together a set of advanced AI methods that allow us to address such challenges and promote social good. We will cover a wide range of topics in AI, including:

  • Optimization [OPT]: convex optimization, mathematical programming
  • Game theory and mechanism design [GT]: computational game theory, mechanism design with and without money, human behavior modeling
  • Machine Learning [ML]: classification, clustering, probabilistic graphical models, deep learning
  • Sequential Decision Making [RL]: Markov Decision Processes (MDPs), partially observable MDPs, online planning, reinforcement learning

In addition to providing a deep understanding of these methods, the course will introduce which societal challenges they can tackle and how, in the areas of (i) healthcare, (ii) social welfare, (iii) security and privacy, (iv) environmental sustainability. The course will also cover special topics such as AI and Ethics.

The course content is designed to not have too much overlap with other AI courses offered at CMU. Although the course is listed within SCS, it should be of interest to students in several other departments, including ECE, EPP and SDS.

(9 Unit) The students in this 9-unit course are expected to have taken at least three mathematics courses covering linear algebra, calculus, and probability. The students will work in groups on a systematic literature review or a project exploring the possibility of applying existing AI tools to a societal problem, with a survey paper or technical report and presentation delivered at the end of the semester.

(12 Unit) This 12-unit course is only open to graduate students (master and Ph.D. students) with previous programming experience and background knowledge in artificial intelligence. The students will work in groups on a research project with a research-style paper and an oral presentation delivered at the end of the semester. Please see the instructor if you are unsure whether your background is suitable for the course.

Learning Objectives

At the end of the course, the students should be able to

  • Identify societal challenges that can potentially be tackled by AI methods, and determine which AI methods can be applied
  • Describe the AI methods covered in the course, including the basic concepts, the key algorithms, and the commonly-used implementation of the methods
  • Model the societal challenges as mathematical problems that AI techniques can be applied and propose how to adjust and modify the AI techniques to fit the problems
  • Describe the evaluation criteria and methodologies of applying AI methods for social good
  • Deliver written and oral presentation on research projects or research survey

Assessments

The final course grade will be calculated using the following categories:

Assessment Percentage of Final Grade
Class participation 10 points
Paper Summaries 20 points
Written Answers Assignment 20 points
Final Project 50 points
  • Class participation. The grading of the class participantion will be mostly based on attendance, checked by in-class quizzes and asking and answering questions in class. Other factors include asking and answering questions on Canvas.
  • Paper reading assignment. The course will require all students to complete weekly paper reading assignments individually. In each assignment, the students are required to provide a summary of the paper/article, a list of questions, and a few brainstorming ideas. The assignments will be submitted through Canvas and will be peer-reviewed, but the final score will be provided by the instructor and the TA. For each student, the lowest scored assignment will be dropped.
  • Written answers assignment. The course will require all students to complete biweekly written answers assignment individually. Each written answers assignment will involve checking the understanding of basic concepts and working through the algorithms presented in class on example problems. Most questions are multiple-choice questions or numerical answer questions. In addition to providing the answers, the students are required to provide explanations to the answers. The answers will be submitted and auto-graded through Canvas. The explanations will be checked through peer review. For each student, the lowest scored assignment will be dropped.
  • Final project. The students will work in small groups (1-3 students in each group). The students are expected to focus on one or more societal challenges, summarize or propose models and AI-based solutions to tackle the challenges and evaluate the solutions. The students are required to submit the project report through Canvas and deliver an oral presentation. The instructor will provide suggested project topics. The students can also propose their own projects topics related to AI and Social Good but they will need consent from the instructor. The progress of projects will be checked through the Project Proposal, Project Progress Report, Project Presentation, and Final Project Report. The proposal and progress report will be peer-reviewed. The presentation and the final report will be evaluated by the instructor and TA directly.
  • The students who choose the 12-unit section will work on a research project, with a research-style paper and an oral presentation delivered at the end of the semester. Ph.D. students may choose a paper format with the guidance of their advisors. For master students, a sample research-style paper can be found here: https://feifanginfo.files.wordpress.com/2016/11/2015_aaai_csworkshop_repeatedssg.pdf
  • The students who choose the 9-unit section will work on a systematic literature review or a project exploring the possibility of applying existing AI tools to a social good problem, with a survey paper or technical report and presentation delivered at the end of the semester.

Students will be assigned the following final letter grades, based on calculations coming from the course assessment section.
