Frequently Asked Questions

Q: I just found this website, what should I do next?

A: Please read through this FAQ and the Syllabus page. If you are registered (or waitlisted) for the course, the course staff will enroll you in the technologies we will use for communication (Piazza) and homework assignment submission (Autolab, Gradescope). If it is after the first day of class, you have been registered for more than two days, and you still don’t have access to one of these, then go ahead and enroll yourself in Piazza using your Andrew Email and send a “Private Note” to the instructors that includes your Andrew ID.

Q: How does 10-301 differ from 10-601?

A: Undergraduates must register for 10-301 and graduate students must register for 10-601. Otherwise, the courses will be identical in all respects.

Q: How does Lecture 2 differ from Lecture 1?

A: Each semester, we run into the same problem: More students register for this course than we have seats in the classroom.

To address this issue, we’ve created an online section (Lecture 2) this semester that is identical to the other section (Lecture 1) except that the lectures are viewed at the same time online. Students in the online sections will be required to attend exams in-person and will have access to all other in-person aspects of the course (e.g. office hours). If you join, you will be a full part of the course. Here’s the best part: If physical seats open up in the other sections, you will be able to join for in-person lectures too.

Regardless of whether you’re signed up for the in-person lecture (Lecture 1) or the online one (Lecture 2), you will sign up for an in-person recitation (Sections A, B, C, D).

Can we guarantee students in Lecture 2 will eventually get a seat? No. However, the historical stats are in your favor. Last spring, there was space for most students within several weeks. Last fall, about half the students got a seat.

So if you are currently waitlisted for Lecture 1, we encourage you to sign up for Lecture 2.

Q: How do I watch the “livestream” of the lectures / recitations.

A: Click the video link on the Schedule page. Log in with your Andrew ID. That same link will allow you to watch the lecture recording later that same day after it has finished uploading (typically a couple hours after the end of the lecture).

Q: I’m signed up for Lecture 2, but the time is listed as “T” or “TBD”. What gives?

A: This is a bug in the registrar’s system, we’ve noticed them about it already. Students in the online section are expected to either watch the online livestream of the lecture at the same time as the corresponding in-person lecture, or they may watch the video recording online later that same day.

Q: Will I be able to get off the waitlist?

A: No one should be on the waitlist. Just sign up for Lecture 2 (see above), which has infinite capacity. (There is a bug in the registration system that occasionally causes a waitlist on Lecture 2. However, someone will manually add you within a week.)

Q: Does this course have recitations?

A: This term, we will have occasional recitations on Friday. The exact time and location depends on which section you are in (Sections A, B, C, D). Consult your course schedule for details. Some of them will review the material from the previous week. We might also include a few to review background and prerequisite material. We’ll interchangeably refer to these as “recitations” and “review sessions”.

Whenever we are having a Friday session, it will be listed on the Schedule page.

Q: What is the difference between Sections A, B, C, D?

A: Sections A, B, C, D are the recitation sections. The only difference between them is the time and location. The content of the recitations will be the same. The recitations will be lead by a team of TAs responsible for that recitation’s topic, so you’ll get to know different TAs throughout the semester.

Q: Will the recitations be in-person or livestreamed?

A: All recitations sections (Sections A, B, C, D) are in-person, since they highly interactive problem solving sessions. That said, if you are for some reason unable to come in person, you may also watch the livestream of the 9:00AM recitation on Fridays; the other recitations are not livestreamed. Note that video recordings of the recitations will not be available after the recitation, i.e. you must watch the livestream in real time.

Q: May I register for the course if I have a course conflict with the lecture time?

A: Yes, you may sign up for the online section (Lecture 2). You must watch the lecture video recording later the same day as they were given .

Q: May I register for the course if I have a course conflict with the recitation time?

A: Yes, but this requires special permission of the instructor. Specifically, you would need to acknowledge that you would be taking the course without access to the optional recitations since they are only available via a livestream or in-person; no recitation videos will be made available.

Q: Where can I review the course policies?

A: See the Syllabus page for tentative course policies.

Q: What does grading look like for this course?

A: The grading is based on exams, homeworks, and class participation. See more details in the Syllabus page.

Q: Does the course focus on real-world applications or theory of ML?

A: Both! As compared to 10-701, this course focuses a bit less on theory, but it certainly still makes a prominent appearance. See the machine learning course comparison for more details.

Q: Will there be programming language requirements for the homework?

A: Yes. Grading of the programming assignments will be done via Autolab. For each one, we will allow you to pick between a small predefined set of programming languages (last time there were four: Python, C++, Java, Octave). You will be expected to know, or be able to quickly pick up, that programming language.

Q: Since 15-122 is one of the prerequisites, will I need to be proficient in C?

A: No, we will not require you to be proficient in C. Though there is a (very small) chance it would be one of the supported programming languages. See the programming language requirements question above.

Q: Do I have the appropriate background for this course?

A: Please see the Prerequisites section of the Syllabus page.

Also, check out our course comparison of the various Intro ML offerings. At the bottom of the course comparison is a self test. You can use it to gauge how comfortable you are with the appropriate math background. It might be appropriate for you to take MLD’s new short course 10-606/607 that might help you catch up on any math background (10-606) or computer science background (10-607) that you are missing.

Q: As an undergrad, can I take this course if I haven’t met the official prerequisites?

A: In general, the only case I make exceptions for is the following: if you are missing only one prereq, will take it as a coreq, and can make a strong objective argument why you have the necessary background, then I will consider your case. If this applies to you, please email the instructor an unofficial transcript for a review of your prior coursework. In your email, please make a case for each prereq you’re missing. Most requests are denied.

Q: Is this course appropriate for someone interested in artificial intelligence?

A: Absolutely! Machine learning has become a key component of artificial intelligence systems deployed throughout the world. There are other excellent courses that provide a broader picture of AI as well (see 15-381 and 15-780 for example).
