Back to the ML/DL Course - 2023 Fall (AI5213/EC4213)

Course Outline

This course is an introductory course on traditional statistical machine learning. Topics include: linear regression, classification, sampling methods, model selection, tree-based methods, support vector machine, deep learning, unsupervised learning, survival analysis, and hypothesis testing. Prior knowledge in basic statistics and programming (Python) is recommended.

PDFs are available on below links.

Homework and Exams

Submit your assignments at the EC4213/AI5213 Gradescope. If you need the entry code, find it on Ed Discussion in the post entitled “Gradescope invitation link”

The midterm will take place on Monday, Oct 23 in GIST College Building C, Room 104.

The final exam will take place on Wednesday, Dec 6 in GIST College Buildge C, Room 104.

If you have a conflict with any of the exams, let us know as soon as possible, and we will schedule a makeup. All exams will be closed book with a single A4-size (both sides) crib sheet. The crib sheets must be handwritten, which is created and printed on an iPad are not acceptable. Exams will cover material from lecture, sections, the readings, and the project. In particular, you are likely to do poorly on the exams and in the course if you do not do your share of the homeworks and projects.

ML Challenge

You will be taking part in a machine learning contest, either as a team or individually. Participate in one of the following challenges:

Upon the conclusion of your chosen contest, your project outcomes will be showcased through two mediums: a poster presentation and a detailed project report.

Here is a link for team formation (Submit by Sep 24)

Poster Presentation

The purpose of the poster presentation is to share your project outcomes with your peers. It’s a chance for you to showcase the hard work you’ve put into your project and engage in insightful discussions with your colleagues.

  • Poster Specifications: A0 size (841 x 1189 mm), portrait orientation (세로 방향), here are some templates: A, B, C.
  • Printing Information: For printing, reach out to 첨단문화사. To ensure timely printing, ask them to print your posters at least 4-5 days in advance.
    • Address: LG Library A, 1F, GIST
    • Direct Line: 062-973-2686
    • E-mail:
  • Venue: Bridge between GIST College B and C (N5 and N6, 3F)
  • Presentation: Dec 4, 13:00-14:30 (TAs will be available from 12:00 to help you set up your posters)
  • Workload Adjustment: To address concerns about additional workload, HW6 will be substituted by this poster presentation. Submit the PDF version of your poster through GradeScope by Dec 3, Sunday 23:59.

The posters will be grouped by project, and you’ll be informed of your specific placement location. Let’s make it a great event!


Project Report

Articulating your ideas and experimental results in writing is pivotal, not only for this course but for your future academic and research endeavors. The project report complements your poster presentation, providing a comprehensive insight into your analytical capabilities and methodological rigor.

Late Policy

The policy is simple: there are no slip dates. If assignments are late, they are increasingly penalized as follows: within 24 hours, you lose 10%; within 48 hours, you lose 20%; within 72 hours, you lose 40%. More than three days late, you can no longer hand-in the assignment. Note that the penalty scheme applies to project deadlines too.


The course will be graded on a curve (25% A, 25% B+, 25% B, 15% C+, 10% C). Median course grade is generally placed in neighborhood of B/B+ border. A+ is reserved for the very few best students in the class. The curve can shift up for an especially excellent class, as indicated but strong classroom interaction and outstanding project implementations. Graduate students and reentry students are not included in establishing the curve (to be fairer to undergraduates), but they will receive grades based on where they would fall on the curve.

  • Six homework (48%, 8% each)
  • Midterm (16%)
  • Final Exam (16%)
  • Project: ML Challenge (20%)

Collaboration Policy & Honor Code

Study groups are allowed. It is also OK to get clarification (but not solutions) from books or online resources, again after you have thought about the problems on your own. However, we expect students to understand and complete their own assignments. Each student must write down the solution independently and hand in one assignment per student, which means you write your solution after closing the book and all your notes, without helped by your colleagues. If you studied together as a group, please cite your collaborators fully and completely at the top of your assignment (e.g., “Junho explained to me what is asked in Question 2.1”). When in doubt about collaboration details, please ask us on Ed discussion.

If elements of two assignments are determined to be clearly very similar, we believe that they were done together or one was copied from the other), then the course grade for all students involved in the incident will be reduced by one letter grade for the first offense, and to an F for the second offense. (All means both the copy-ers and the copy-ees). The grade for that assignment will also be reduced to 0. More serious cases of cheating (e.g., cheating on exams) will lead to severe consequences ranging from a grade of “F” on the class to suspension from the University.
