CS 7643 Deep Learning

Fall 2017, TR 4:30 - 5:45 pm, Clough 144

Course Information

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 expose students to cutting-edge research — starting from a refresher in basics of neural networks, to recent developments. The course is structured in “modules” (background, CNNs, RNNs, Deep Structured Prediction, Deep Reinforcement Learning). Each “module” will begin with instructor lectures to present context and background material. The emphasis will then switch to student-led paper presentations and discussions.

Late policy for deliverables

  • No penalties for medical reasons (bring doctor’s note) or emergencies.
  • Every student has 7 free late days (7 x 24-hour chunks) for this course; these cannot be used for HW0, the reviews or the presentation.
  • After all free late days are used up, penalty is 25% for each additional late day.


CS 7643 is an ADVANCED class. This should not be your first exposure to machine learning. Ideally, you need:

  • Intro-level Machine Learning
    • CS 7641/ISYE 6740/CSE 6740 or equivalent
  • Algorithms
    • Dynamic programming, basic data structures, complexity (NP-hardness)
  • Calculus and Linear Algebra
    • positive semi-definiteness, multivariate derivates (be prepared for lots and lots of gradients!)
  • Programming
    • This is a demanding class in terms of programming skills.
    • HWs will involve a mix of languages (Python, C++) and libraries (PyTorch).
    • Your language of choice for project.
  • Ability to deal with abstract mathematical concepts


  • The class is full. Can I still get in?

    It is unlikely. The class is full, with a 200 person wait-list. It is unlikely that the class size will increase further. We recommend coming to the first class. There will be a HW0 released on day 1 to check background preparation. Our past experience with HW0 suggests that slots will open up after some students drop the class.

  • I have not taken an graduate-level “Machine Learning” class or I am taking it in parallel. Can I still take this class?

    No. Graduate-level machine learning is a pre-requisite.

  • Can I audit this class or take it pass/fail?

    No. Due to the large demand for this class, we will not be allowing audits or pass/fail. Letter grades only. This is to make sure students who want to take the class for credit can.

  • Can I simply sit in the class (no credits)?

    In general, we welcome members of the Georgia Tech community (students, staff, and/or faculty) to sit-in. Out of courtesy, we would appreciate if you let us know beforehand (via email or in person). If the classroom is full, we would ask that you please allow registered students to attend.

  • I have a question. What is the best way to reach the course staff?

    Registered students – your first point of contact is Piazza (so that other students may benefit from your questions and our answers). If you have a personal matter, email us at the class mailing list cs-7643-f17-staff@googlegroups.com.


  • You are encouraged to try out interesting applications of deep learning (vision, NLP, computational biology, UAVs, etc!)
  • The project must be done in this semester. No double counting.
  • You may combine with other course project but must delineate the different parts
  • Extra credit for shooting a publication
  • Main Categories:
    • Application/survey - compare a bunch of algorithms on a new application domain of your interest
    • Formulation/Development - Formulate a new model or algorithm for a new/old problem
    • Theory: Theoretically analyze an existing algorithm.
