Dear students,
UNSW has informed us that the COMP9418 exam will run on Tuesday, 20/08/2024 .
The exam will last 12 hours, starting 20/08/2024 at 9:00 a.m. AEST and ending at 9:00 p.m. AEST. We will answer questions during the entire exam period. Any issues should be posted in the WebCMS forum (general matters) or emailed to cs9418@cse.unsw.edu.au (sensitive ones).
The exam will be available in WebCMS, and it will be a Jupyter notebook. You must write all answers in the notebook and submit them by give (command line or WebCMS) before the deadline.
The exam will have three parts:
The exam will require around 3 hours. Therefore, you must reserve at least 3 hours to work on the exam that day. We will not require you to submit the answers in 3 hours. The only requirement is to submit your exam before the deadline (20/08/2024 at 21:00 AEST). No late submissions will be accepted. If you do not submit your exam on time, we will consider that you did not participate. You will need to apply for a supplementary exam.
Some students may have another exam on the same day (morning or afternoon). In this case, you should reserve your free period for the COMP9418 exam.
You will need a computer with the same libraries used in tutorials to solve the exam programming questions. You can use your computer, Google Colab or the UNSW CSE VLAB computers using software such as TigerVNC. The exam will be an open-book exam. Therefore, you can access papers, books, and course materials, including slides and solved tutorials. You cannot communicate (email, phone, message, talk, etc.) except with the COMP9418 staff via email or forum. Deliberate violation of exam conditions will be referred to Student Integrity as serious misconduct.
Regards,
Gustavo.
Dear students,
The course material for this week can be found on WebCMS. This week's topic is approximate inference, and we cover Belief Propagation and Sampling. The tutorials will cover Gaussian Models, including Kalman Filters.
The myExperience survey is open. Please take a moment to complete the survey form before 08/08. The feedback from previous students helped us significantly improve COMP9418, and we greatly appreciate your feedback. You can access the survey form using this link: The myExperience survey is now open.

Dear students,
Happy flexibility week!
This week, we do not have lectures, tutorials, quizzes or consultation hours. You can use this time to catch up with the course content.
Regards,
Gustavo.
Dear students,
I apologise, but I found a bug in my code that generated the test cases. The bug caused the TAN model's accuracy to be higher than the correct value.
I have updated the assignment 1 changelog, and uploaded a new notebook with fixed test cases for these two tasks.
Regards,
Gustavo.
Dear students,
I have finished updating the course page on WebCMS.
We are approaching the assignment 1 due date this Sunday at 6 p.m. Some students have found some issues with the assignment description. I have made some changes to the notebook to fix these errors. Please check the changelog on the
Assignment 1 page on WebCMS
and download the latest version of the notebook.
Remember to register your group for assignment 1 in WebCMS if you are working in groups. To do so, you can go to WebCMS, Groups Tab, and add your group.
The fourth quiz is also due this Sunday at 6 p.m.
Regards,
Gustavo.
Dear students,
You will find the course content for this week on WebCMS. Do not forget to submit your answers to this week's quiz (due Sunday at 6 pm).
I uploaded a recording for the Week 2 Thursday lecture on ECHO360 and WebCMS. I re-recorded this lecture because the camera did not record the entire whiteboard. The problem is solved, and the Week 3 Thursday lecture is recorded correctly.
Regards,
Gustavo (on behalf of the COMP9418 team).
Dear students,
Welcome to Week 3. This week, you will find on WebCMS:
Assignment 1 is available on WebCMS and is due 30th of June (Sunday) at 6:00 pm. You can work on this assignment individually or in a group of two students.
I cancelled today's lecture because I am feeling sick. I will cover today's lecture content this Thursday. I will also discuss the assignment description and answer questions about it.
Finally, I will re-record the content of last Thursday's lecture and post it on WebCMS and ECHO360. It should be online tomorrow if I feel better.
Regards,
Gustavo.
Dear students,
I am sick (flu-like symptoms) and need to take the day off today.
Next Thursday, we will cover the weekly review and solve some exercises.
Regards,
Gustavo.
Dear students,
Our first quiz is due Sunday at 6 p.m. You can make multiple submissions, but only the last one will be marked.
Also, as Monday is a holiday, you will receive our weekly email update on Tuesday before noon.
Regards,
Gustavo.
Dear students,
A new recording of the Thursday lecture is available on WebCMS and Echo360. On WebCMS, go to Lecture Videos, and you will find this lecture listed together with the Week 1 videos.
Regards.
Dear students,
We have finished uploading the course material for this week. You will find on WebCMS:
Starting this week, we have a weekly quiz. The quizzes are multiple-choice questions. Please submit your answers before Sunday at 6 pm. We will not accept late submissions for quizzes.
You can find the quizzes under the menu Activities in WebCMS.
The live lecture recordings are in Echo360. We have posted a link on WebCMS. On Thursday, I could not get the projectors to work with my iPad, so I used the whiteboard. I tested my equipment, and it seems the problem is solved. From now on, I should use an iPad to make notes.
I will re-record Thursday's lecture and post it on WebCMS and Echo360. When it is available, I will email you.
Regards,
Gustavo.
Dear students,
Martin misunderstood my instructions and did not appear in today's tutorial. I will blame my Brazilian accent for this one!
My sincere apologies. Please let me know if you can join another tutorial this week. Martin will deliver a tutorial tomorrow (Wed 4-6 pm) (preferred), and Yunrui will deliver the tutorials on Thursday and Friday (9-11 am).
Send me a message if you cannot join any of these tutorials, and we will make an online tutorial, record and post it on WebCMS.
Regards.
Dear students,
Welcome to COMP9418!
COMP9418 will run in the format of flipped classrooms. In the lectures, we will review the previous week's content on Tuesdays and discuss one exam exercise in Thursday's classes.
One exception is Week 1, as we need content to review. On Tuesday, I will present the course and explain the course logistics. Thursday, we will solve a textbook exercise together.
You can find on WebCMS COMP9418 page (https://webcms3.cse.unsw.edu.au/COMP9418/24T2/) the following:
The material is online for all ten weeks so that you can study independently.
The practical part of the tutorials is a Jupyter Notebook that runs on Google Colab.
Starting Week 2, we will have weekly quizzes, and the quizzes and other assessments are due on Sundays at 6 pm. Also, beginning in Week 2, we will post the answers to the previous week's tutorial on Monday mornings.
Therefore, check for new material on Mondays and submit your work before 6 pm on Sundays.
I will explain the course on Tuesday and answer your questions about its organisation. Starting next week, Tuesday's classes will have a summary of the previous week's content + consultation. Thursday's lectures will discuss exam exercises.
I hope you will enjoy the course!
Regards,
Gustavo (on behalf of the COMP9418 team).
