- All content will be on github in this repo including schedule and tech setup instructions
- All assignments will be on and submitted through canvas
- Class communication and announcements will be primarily through Slack
The first few weeks will be hands-on tech sessions in HBH 1006 and for the remainder of the semester, we'll use the time on Wednesdays to meet with teams and check in about their progress on the project. We'll post the timing and location for each project team here when it becomes available.
This is a project-based course designed to provide training and experience in solving real-world problems using machine learning, with a focus on problems from public policy and social good.
Through lectures, discussions, readings, and project assignments, students will learn about and experience building end-to-end machine learning systems, starting from project definition and scoping, to modeling, to field validation and turning their analysis into action. Through the course, students will develop skills in problem formulation, working with messy data, communicating about machine learning with non-technical stakeholders, model interpretability, understanding and mitigating algorithmic bias & disparities, evaluating the impact of deployed models, and understanding the ethical implications of design choices made throughout the pipeline.
Pre-Requisites: Students will be expected to know Python (for data analysis and machine learning),SQL, and have prior graduate coursework in machine learning. This course assumes that you have taken graduate Machine Learning courses before and is focused on teaching how to use ML to solve real-world problems. Experience with *nix command line, git(hub), and working on remote machines will be helpful and is highly recommended.

Textbook: The course will rely on selected readings from various sources and has no required textbook – each week, we’ll have selected readings from a variety of sources, listed below.
Software: For project work, we will provide students with access to a shared data and ML infrastructure. Data will be available in a postgreSQL database and SQL and python will be used throughout the course. Students will be expected to store project code in a shared github repository, so you should create an account if you do not already have one (github.com). Additionally, we will be making use of the machine learning pipeline package triage for modeling. More Details to follow.
Phone, Laptop, and Device Policy
Because much of the work in this course involves group discussions and
responding thoughtfully to your colleagues’ progress reports, mobile
devices are not permitted for use during the class. If you have a disability or other reason that necessitates
the use of a mobile device, please speak to one of the instructors or
teaching assistants.
Beginning in the second week of class, groups of 4 students will
work together on a machine learning project throughout the semester with
one of several real-world public policy problems. Each week, every group
will be expected to provide an update on their current status. In
addition to helping connect readings and discussion topics to an applied
domain, these updates and discussions will give you a chance to elicit
input and feedback from your classmates about challenges you’re facing
(and they likely are too!) in your analyses.
Throughout the semester, students will be responsible for several
intermediate deliverables as they work on their group projects:
-
An initial project proposal, submitted as a group, including the project scope and preliminary descriptive statistics about the entities in their dataset. The proposal should be 4-5 pages in length, not including figures, tables, or references and should include the provided scoping sheet as an appendix.
-
A technical ML plan, submitted as a group, detailing how the scope described in their proposal can be formulated as a machine learning problem and the elements of the pipeline the group will be building.
-
A description of specific features to be built for the modeling project, submitted as a group and describing the underlying data, level at which information is available, aggregation strategies (e.g., over time or geography), and plan for handling missing values.
-
An in-class project mid-term update presentation (approximately 7 minutes in length plus 3 minutes for questions), describing the problem setting, approach, pipeline, and initial results.
-
Brief weekly update assignments to guide our check-in discussions. These typically take the form of filling results or modeling details into a handful of template slides. These updates will be graded for completeness and correctness, however we expect this work to be iterative and errors identified in one week’s update that are corrected by the next week can result in revision of the previous score up to 80% of the total possible.
At the end of the semester, each group will be responsible for a final
presentation (10 minutes in length plus 3 minutes for questions). While
the deep dive presentations should be more technical in nature, the
final presentation should be geared towards the relevant decision makers
for your project, including an overview of the problem and approach,
your results, policy recommendations, and limitations of the work.
Accompanying the final presentation is a written report, approximately
15 pages in length, which should include:
-
An executive summary not to exceed 1 page that succinctly describes the project, results, and recommendations.
-
An overview of the problem, its significance, and the scope and goals of the current work.
-
A description of the methodology and results of the analysis. The report should also provide a link to well-documented code in your group’s course github repository.
-
Brief (1-2 paragraph) design of a field trial to evaluate the accuracy of the resulting model in practice as well as its ability to help the organization achieve its goals.
-
Concluding lessons and recommendations for the partner organization.
-
Optionally, you may also wish to include a proposal for future avenues of research beyond the scope of this work, for instance on novel machine learning methods to improve on the current work, new policy interventions to evaluate or explore, or other related research opportunities.
In general, the course will be structured around three sessions each week:
-
During the Tuesday sessions, we’ll focus on structured lectures and discussions of the weekly topic (including a mix of live lectures and discussions of pre-recorded content throughout the semester).
-
During the Wednesday lab/recitation sessions, we’ll discuss technical skills and tools you’ll need for the project work early in the semester and then shift to check-ins with each team to discuss the status of their project work, generally surround short update assignments due on Monday (each team should review the updates of all teams working on the same project and the discussion will involve feedback from your peers and the instructors).
-
Early in the semester, Thursday sessions will also focus on lectures and discussions, but once the projects are underway, most weeks will reserve this time for group meetings and project work (note that attendance on zoom is still mandatory at this time – one piece of feedback we received in the last iteration of the course was that many groups had trouble coordinating regular meeting times, so we wanted to find a way to dedicate some class time to help resolve this challenge).
Although we’re dedicating some time in class to work with your group, please note that successfully completing the project will require considerable work outside of class time as well and will constitute the majority of the “homework” for the course.
Below is a preliminary schedule of the course, including the readings that will be assigned for that week. Please be sure to have read and be prepared to discuss the readings before the specified class session. Most of these topics can be (and often are) the focus of entire courses and generally we’ll only scratch the surface, but hopefully inspire you to delve deeper into areas that interest you (and you’ll find plenty of open research questions in each). Optional readings are also listed for most sessions which may be of interest to students who wish to delve deeper in a given area as well as provide additional context for your related project work.
-
Week 1 (Aug 29, Aug 31): Introduction and Project Scoping
On Tuesday, we’ll provide an introduction to the class, its goals, and an overview of the project options to help you decide what you’re interested in working on for the remainder of the semester.During the Wednesday session, we’ll help ensure everyone is set up to access the class technical resources.
On Thursday, we’ll talk about scoping, problem definition, and understanding and balancing organizational goals. Well before the outset of technical work, a decision needs to be made about whether a given policy problem can and should be addressed with machine learning: is the problem significant, feasible to solve with a technical approach, and of sufficient importance to policy makers that they will devote resources to implementing the solution? How will success be measured? How will (often competing) goals of efficiency, effectiveness, and equity be balanced?

Week 2 (Sep 5,7): Case Studies and Acquiring Data
This week, we’ll organize groups and begin project workPractical examples can provide a great way to gain an understanding of the nuance of applying machine learning to policy problems, so Tuesday will focus on a class discussion of a case study of a recent application, scoping the case together in breakout sessions.
Required Reading for Tuesday:
- Fine-grained dengue forecasting using telephone triage services by Rehman, NA, et al. Sci. Adv. 2016. Available Online
During the Wednesday session, we will lead a workshop on using remote workflow tools for your class project.
On Thursday, we’ll delve into some of the details of acquiring data, protecting privacy, and linking records across data sources. Acquiring data from a project partner is often an involved process with a number of legal and technical aspects. Researchers need to understand how the data acquired may and may not be used (typically formalized in a data use agreement as well as underlying law) and ensure that the privacy of individuals in the dataset is protected (potentially both through access restrictions and techniques like anonymization). Once data has been acquired, it often needs to be transformed to ingest into the system used for analysis, records from multiple data sources linked, and data structured for further analysis.
During class on Thursday, we’ll also talk a little bit about working together with your project team.

Week 3 (Sep 12,14): Data Exploration, Analytical Formulation, and Baselines
Work on your project during this week should include continuing to develop and refine your scope as you begin to explore the data. You’ll also need to prepare and load some data into a database in order to make use of it in your modeling.Tuesday of this week will provide a crash course in exploratory data analysis. Data exploration is fundamental to developing an understanding of the nuances of the data and how the policy problem you initially scoped can be specifically formulated as a machine learning problem. This process involves generating and plotting summary statistics, exploring trends over time and understanding rapid changes in distributions, as well as identifying missing data and outliers. Typically, data exploration should involve considerable input from domain experts as you develop an understanding of how the data relates to the underlying generative process, as well as its idiosyncrasies and limitations.
We’ll also dedicate about 30 minutes during class on Tuesday for you to meet with your project teams and discuss your project scope.
During the Wednesday session, we’ll lead a tutorial about using GitHub for your project.On Thursday, we’ll discuss analytical formulation of policy projects. Distinct from the initial scoping, a true analytical formulation of your policy problem can only come after you have developed an understanding of the data at hand, which in turn will often result in a greater understanding of the problem itself. Here, you’ll ask how specifically your target variable (if relevant) is defined in the data, what types of information are available as predictors, and what baseline you’ll be measure performance against. Very rarely is the appropriate baseline as simple as "random choice" or the population prevalence. Rather, it should reflect what would be expected to happen otherwise: perhaps a simple decision rule that an expert would come up with or even a pre-existing statistical model that the current effort is seeking to replace.

Week 4 (Sep 19, 21): Machine Learning Pipeline Overview
At this point in your project work, you should be developing your initial end-to-end pipeline.Due Tuesday, Sep 19: Project proposal with scope and descriptive statistics.
On Tuesday, we’ll describe the components of typical machine learning pipelines. End-to-end ML Pipelines can quickly become unwieldy with several moving pieces and well-structured, modular code is often critical to detecting and fixing bugs in the process. This session will provide an overview of the pipeline, each underlying element, and some best practices for building them.

Week 5 (Sep 26, Sep 28): Choosing Performance Metrics & Evaluating Classifiers, Part I
Pipeline development should continue in your project, with a focus on producing the simplest possible version of the full system.Due Wednesday, Sep 27: Peer reviews of three project proposals.
In most cases, a vast array of methods — each with a number of tunable hyperparameters — can be brought to bear on your modeling question. How do you decide which models are better than others and how can you be confident this decision will carry forward into the future when the model is deployed? How should you balance considerations of performance and fairness when making these decisions? Are models that are performing similarly well giving similar predictions? What should you do if they are not? In this week, we’ll begin to answer these questions, focusing on the choice of performance metrics.
Required Readings for Tuesday:
- Transductive Optimization of Top k Precision by Liu, LP, Dietterich, TG, et al. IJCAI 2016. Available Online

At this point, your group should be continuing to refine and expand on your preliminary modeling results.Due Monday: Weekly project update with updated validation splits, features, and “version 0” baseline results.
This week, we’ll return to our discussion of model selection, delving into the details of winnowing down a large number of model specifications to one or a handful that perform "best" for some definition of "best". In particular, we’ll focus on the common case of machine learning problems with a strong time series component and the desire to balance performance and stability in model selection.
On Wednesday, we’ll continue our group check-ins and on Thursday, you’ll time to work with your project group.
-
Week 11 (Nov 14,16): Model Interpretability and Ethics Workshop (Thursday)
By this week, project work should be beginning to focus more heavily on evaluation, model selection, and interpretation.Due Monday, Nov 13: Weekly project update.
Model interpretability can be thought of at two levels: global (how the model works in aggregate) and local (why an individual prediction came out as it did). This week, we’ll focus on some practical aspects and applications of interpretability at the two levels: understanding how a model is performing globally, what it means to compare this performance across model specifications, how these methods can help researchers debug and improve their models, build trust among stakeholders (including a growing legal movement towards a "right to explanation"), help those acting on model predictions understand when they should override the model with their judgement, and importantly help those actors decide not only on whom to intervene but suggest what sort of intervention to take.

Attendance: Because much of this course is focused on discussion with your classmates, attending each session is important to both your ability to learn from the course and to contribute to what others get out of it as well. As such, you’ll be expected to attend every session and your participation will factor into your grade as described above. Should anything come up will require you to miss a class (illness, conferences, etc), please let one of the course staff know in advance.
Academic Integrity: Violations of class and university academic integrity policies will not be tolerated. Any instances of copying, cheating, plagiarism, or other academic integrity violations will be reported to your advisor and the dean of students in addition to resulting in an immediate failure of the course.
Data Security: As noted above, the data used for the project work in this course should be considered sensitive and care must be taken to protect the privacy of those in the dataset. The data must remain on the computing environment provided for the class and attempts to download it to any other machine will result in failure of the course.

Students with Disabilities: We value inclusion and will work to ensure that all students have the resources they need to fully participate in our course. Please use the Office of Disability Resource’s online system to notify us of any necessary accommodations as early in the semester as possible. If you suspect that you have a disability but are not yet registered with the Office of Disability Resources, you can contact them at access@andrew.cmu.edu
Health and Wellness: As a student, you may experience a range of challenges that can interfere with learning, such as strained relationships, increased anxiety, substance use, feeling down, difficulty concentrating and/or lack of motivation. These mental health concerns or stressful events may diminish your academic performance and/or reduce your ability to participate in daily activities. CMU services are available, and treatment does work.
All of us benefit from support during times of struggle. There are many helpful resources available on campus and an important part of the college experience is learning how to ask for help. Asking for support sooner rather than later is almost always helpful.
If you or anyone you know experiences any academic stress, difficult life events, or feelings like anxiety or depression, we strongly encourage you to seek support. Counseling and Psychological Services (CaPS) is here to help: call 412-268-2922 and visit their website at cmu.edu/counseling/. Consider reaching out to a friend, faculty or family member you trust for help getting connected to the support that can help.
