Announcements

The final exam is scheduled to be held in 4-270 on Fri 05/16/2025, 9:00 AM–12:00 PM.
Welcome to the class! We look forward to seeing you on the first day.
Please sign up for Piazza. All course communication, including questions to the instructors, should go through Piazza.
Take this prerequisite self-assessment to ensure you have the relevant background for the class.
Recitation will be required. This class will have a final exam, but no midterm.
We expect you to attend all lectures and recitations, and will do a virtual roll call for each using the following links:

When readings are posted for a lecture, we expect you to provide us a brief summary of that reading by the day after the corresponding lecture. Three relevant bullet points are sufficient. Please submit these at the following link:

Reading summary submission

Course description

Introduces students to machine learning in healthcare, including the nature of clinical data and the use of machine learning for risk stratification, disease progression modeling, precision medicine, diagnosis, subtype discovery, and improving clinical workflows. Topics include large language models, causality, interpretability, algorithmic fairness, time-series analysis, graphical models, deep learning, transfer learning, genomics, and computational biology. Guest lectures by clinicians from the Boston area and course projects with real clinical data emphasize subtleties of working with clinical data and translating machine learning into clinical practice.

Schedule

The schedule for classes is under revision and is still in draft form.

Reading Assignments

Many of the lectures are associated with related papers that should help you think about the lecture topic. For each reading assignment, you are expected to submit a brief summary of the three most important ideas of the paper, as short bullet points.

Problem sets

The problem sets pdfs will be available here (not that some data for the problem sets is not publicly available):

Projects

We are recruiting a group of doctors with interesting clinical problems to mentor teams of students who will work on them. We will form teams and match to problems/mentors a few weeks into the class. We will release the project guidelines and detailed information in Canvas.

Grading

40% course project
30% homework (~4 problem sets; both theory & practice)
20% final exam
5% participation – note: class attendance is required (with obvious exceptions for illness, etc.)
5% reading responses

Late Policy (starting for pset1 onwards)

[4 "slack" days] We understand that sometimes things outside one's control prevent submitting by the deadline. As such, each student is given 4 "slack" days that they can use throughout the semester (e.g. you could submit four psets one day late each or you could submit one pset three days late and another one day late) without a late penalty. The days do not subdivide into sub-day units: 2 hours late would spend one of the slack days without 22 hours of "rollover". In your pdf writeup, specify how many slack days you are using (they cannot be used retroactively).
[10% off per unexcused late day.] If you submit a pset 3 days late and use 1 slack day, then this is 2 unexcused late days, which translates to 20% off your homework.
[Max 4 days late.] Homework will not be accepted after 4 days late, regardless of how many slack days are used, absent communication from S3 or OGE.
[write on homework] In order to use a slack day, students must include it in writing on their submission pdf. Otherwise, TAs will assume no slack days used and deduct 10% for each late day.

Scenarios:

Sam uses 2 slack days on HW3. This is the first time Sam has used any slack days. Sam now has 2 remaining slack days and receives her homework score with no penalty.
Jamie uses 1 slack day on HW3 but submits 52 hours after the deadline. Therefore Jamie is 3 days late (rounded up) and receives 20% off the graded homework. This is the first time Jamie has used any slack days, so Jamie now has 1 slack day remaining.
Cory has never used any slack days, but submits HW5 100 hours late with no note / communication from S3 or OGE. This is more than 4 days after the deadline, so the work is not accepted, and Cory receives a zero.

Use of Generative AI

You may choose to use generative AI tools to help think through problems, but not to produce solutions to the problem sets. In your problem set solutions, you must indicate any external resources consulted, including Generative AI. The course staff reserves the right to ask you to explain the rationale for any answer if it appears that it is not original to you. Pedagogically, you will learn much more from working through any problem on your own, and this will be reflected in your final exam scores, which will be closed-book and without access to any Generative AI.
