CS 4644 / 7643 Deep Learning
Spring 2023, Wed/Fri 12:30pm - 1:45 pm, Clough UG Learning Commons 152
This is an exciting time to be studying (Deep) Machine Learning, or Representation Learning, or for lack of a better term, simply Deep Learning!
Deep Learning is rapidly emerging as one of the most successful and widely applicable set of techniques across a range of domains (vision, language, speech, reasoning, robotics, AI in general), leading to some pretty significant commercial success and exciting new directions that may previously have seemed out of reach.
This course will introduce students to the basics of Neural Networks (NNs) and expose them to some cutting-edge research. It is structured in modules (background, Convolutional NNs, Recurrent NNs, Deep Reinforcement Learning, Deep Structured Prediction). Modules will be presented via instructor lectures and reinforced with homeworks that teach theoretical and practical aspects. The course will also include a project which will allow students to explore an area of Deep Learning that interests them in more depth.

- There will be no make-up work provided for missed assignments. Of course, emergencies (illness, family emergencies) will happen. In those instances, please contact the Dean of Students office (see here for rules). The Dean of Students is equipped to verify emergencies and pass confirmation on to all your classes. For consistency, we ask all students to do this in the event of an emergency. Do not send any personal/medical information to the instructor or TAs; all such information should go through the Dean of Students.
- Every homework deliverable and project deliverable will have a 48-hour grace period during which no penalty will apply. This is intended to allow you time to verify that your submission has been submitted (we recommend you re-download it and look it over to make sure all questions/deliverables have been answered). Canvas will show your submission as late, but you do not have to ask for this grace period. Deliverables after the grace period will receive a grade of 0.
- Intro-level Machine Learning

- Read first, Write later. Read the ENTIRE set of posts/comments on a discussion board before posting your reply, in order to prevent repeating commentary or asking questions that have already been answered.
- Avoid language that may come across as strong or offensive. Language can be easily misinterpreted in written electronic communication. Review email and discussion board posts BEFORE submitting. Humor and sarcasm may be easily misinterpreted by your reader(s). Try to be as matter of fact and as professional as possible.
- Follow the language rules of the Internet. Do not write using all capital letters, because it will appear as shouting. Also, the use of emoticons can be helpful when used to convey nonverbal feelings. ☺
- Consider the privacy of others. Ask permission prior to giving out a classmate’s email address or other information.
- Keep attachments small. If it is necessary to send pictures, change the size to an acceptable 250kb or less (one free, web-based tool to try is picresize.com).
- No inappropriate material. Do not forward virus warnings, chain letters, jokes, etc. to classmates or instructors. The sharing of pornographic material is forbidden.
The class is full. Can I still get in?
Sorry. The course admins in CoC control this process. Please talk to them.

Late policy for deliverables
CS 4644/7643 should NOT be your first exposure to machine learning. Ideally, you need:
Online Student Conduct and (N)etiquette
Communicating appropriately in the online classroom can be challenging. All communication, whether by email, Piazza, Canvas, or otherwise, must be professional and respectful. In order to minimize this challenge, it is important to remember several points of “internet etiquette” that will smooth communication for both students and instructors
NOTE: The instructor reserves the right to remove posts that are not collegial in nature and/or do not meet the Online Student Conduct and Etiquette guidelines listed above.
Plagiarism & Academic Integrity
Georgia Tech aims to cultivate a community based on trust, academic integrity, and honor. Students are expected to act according to the highest ethical standards. All students enrolled at Georgia Tech, and all its campuses, are to perform their academic work according to standards set by faculty members, departments, schools and colleges of the university; and cheating and plagiarism constitute fraudulent misrepresentation for which no credit can be given and for which appropriate sanctions are warranted and will be applied. For information on Georgia Tech’s Academic Honor Code, please visit http://www.catalog.gatech.edu/policies/honor-code/ or http://www.catalog.gatech.edu/rules/18/.
You are encouraged to discuss problems and papers with others as long as this does not involve the copying of code or solutions. After discussions, all materials that are part of a submission should be wholly your own. Do NOT search for code directly implementing the assignment and submit snippets or variations of them. You can search for conceptual information but NOT code solutions. Any public material that you use (open-source software, help from a textbook, or substantial help from a friend, etc.) should be acknowledged explicitly in anything you submit to us. Our current policy is that you CANNOT use any AI-assisted (e.g. based on large language models such as Github Copilot) text or coding responses in part or whole; again, every piece of text or code you submit must be wholly your own.
If you have any doubts about whether something is legal or not, please do check with the class Instructor or the TA. We will actively check for cheating, and any act of dishonesty will result in a Fail grade. Any student suspected of cheating or plagiarizing on any deliverable including assignments will be reported to the Office of Student Integrity, who will investigate the incident and identify the appropriate penalty for violations.
Students with Disabilities
If you are a student with learning needs that require special accommodation, contact the Office of Disability Services at 404.894.2563 or http://disabilityservices.gatech.edu/, as soon as possible, to make an appointment to discuss your special needs and to obtain an accommodations letter. Please also e-mail me as soon as possible in order to set up a time to discuss your learning needs.
Subject to Change Statement
The syllabus and course schedule may be subject to change. Changes will be communicated via the Canvas announcement tool. It is the responsibility of students to check Piazza, email messages, and course announcements to stay current in their online courses.
Project Details (28% of course grade)
The class project is meant for students to (1) gain experience implementing deep models and (2) try Deep Learning on problems that interest them. The amount of effort should be at least the level of 1.5 homework assignment per group member (2-4 people per group). The deliverables are
- Project Proposal (2%): Due Mar 17 - Final Report (26%): Due May 1st
The final report is a PDF write-up describing the project in a self-contained manner will be the sole deliverable. Your final write-up is required to be between 4 - 6 pages using a template provided with structured like a paper from a computer vision conference (CVPR, ECCV, ICCV, etc.). Please use this template so we can fairly judge all student projects without worrying about altered font sizes, margins, etc. After the class, we will post all the final reports online so that you can read about each others’ work. Additionally, we will allow people to upload additional code, videos, and other supplementary material as zip file similar to code upload for assignments. While the PDF may link to supplementary material, external documents, and code, such resources may or may not be used to evaluate the project. The final PDF should completely address all of the points in the rubric described below.
We will release a detailed project rubric format as the semester progresses.
