Final marks

Posted by Gustavo Batista Wednesday 18 December 2019, 11:07:29 AM.

Hi all,

some details about the marks available in SMS and Astra. SMS is the system maintained by CSE. Astra is a university wise system, and the results are available through MyUNSW.

Since Astra and SMS differ how the partial marks are scaled, I will exemplify with Astra. The final marks are the same in both systems.

In Astra, the three components: assignments average, quizzes average and exam are numbers in the range 0-100. The final mark is a weighted average of these parts.

1. Quizzes. The quizzes were designed to be marked differently compared to how WebCMS3 does. The multiple-choice and multiple-correct-options questions were supposed to be worth one mark per option. Therefore, the student would receive one mark for identifying if each option is true or false. Unfortunately, WebCMS does a different computation, and we had to recompute the marks in a spreadsheet. As discussed, we considered one mark for Quiz 2 - Question 6 - Option c, Quiz 3 - Question 7 - Option c and Quiz 4 - Question 4 - Option d independent of the student answer. We scaled each quiz to the range 0-100 and computed an unweighted average of the four quizzes.
2. Assignments. We scaled each assignment to the range 0-100 and computed an unweighted average of them.
3. Exam. The exam marks were scaled up, so the highest mark of 84/100 became equal to 100.

Finally, we computed the final weighted average considering 0.6 for the exam, 0.1 for the quizzes and 0.3 for the assignments.

If you received a W withheld grade, this means that you did not pass the course, but you have been granted a supplementary exam. In this case, you will be advised by the school of time and location of the supplementary exam. The format of the final exam and conditions is the same as for the original final.

Check your ass1 and ass2 marks to be sure they are entered correctly

Posted by Armin Chitizadeh Saturday 14 December 2019, 09:02:00 AM.

Hi all,

I went through the marks for ass1 and ass2 which were entered wrongly into the system.
Now all ass1 and ass2 marks should be entered correctly. Can you all check it and see if there is any problem. If there is a problem please email me asap.

Use this command to check:

Kind regards,
Armin

Posted by Armin Chitizadeh Tuesday 10 December 2019, 11:23:59 AM, last modified Tuesday 10 December 2019, 11:30:08 AM.

Hi all,

I noticed the system is rounding marks down. I will fix it soon. Also ass2 is not showing for anyone. I will fix it too soon and will let you know.

Still, like the last assignment, you should be able to get your feedback for this assignment.

2 days period for emailing your marker | Checking the actual mark

Posted by Armin Chitizadeh Tuesday 10 December 2019, 09:40:17 AM.

Hi all,

First I want to say for this assignment you only have two days period to email me or the marker. This means no complain will be accepted for the second assignment after Wed 11Dec 11:59 pm.

Second, as I mentioned earlier the csv file that you see is not your actual mark. This is a way that I found to share with you how your assignment was marked, and it means nothing more. Also, it will never be updated.

Your actual mark might be updated if the marker found he or she made a mistake in marking. The actual mark is also out of 15 and late penalties are applied to it. Here is how you can check the actual assignments marks. You should now see your ass1 and ass2 marks:

9418 classrun 19T3 -sturec

If there was any problem, please let me know within two days.

Kind regards,
Armin

You can now see the feedback for your second assignment

Posted by Armin Chitizadeh Tuesday 10 December 2019, 07:52:31 AM.

Hi all,

The feedbacks for the second assignment are entered. Similar to the previous assignment you can collect the feedback file via:

9418 classrun -collect ass1

It asks you if you want to examine it (y/n)?
After you finished examining it, it placed it on your home directory and call it "cs9418.ass2.mark".
It is a csv file of your mark with comments. You might need to add ".csv" to its end in order to open it with excel.

All the group members should have the same mark. But only one member might have the comment.
Let me know here if you are having any problem.

This time I have added a new column called: Marker . It has the name of the person who marked your assignment. If you believe there was a mistake in marking please contact the marker. Here are their email addresses:

Payal: p.bawa@unsw.edu.au
Matt: contact.matt.gibson@gmail.com
Anna: a.trofimova@unsw.edu.au

And if there was a problem such as 'no file found' or something not related to the marker email me directly.

Remember like the previous feedback, this is just a feedback. It is there for you to see the mark for each section of your assignment. It is not your final mark. The marking template for the second assignment will soo be released under Assignment section. I will also soon post a message here for you explaining how to check your actual final mark.

Also, this feedback contains no late penalties.

Kind regards,

Armin

Material update

Posted by Gustavo Batista Sunday 08 December 2019, 04:01:11 PM.

All,

More details about the exam

Posted by Gustavo Batista Saturday 07 December 2019, 05:25:38 AM.

Hi all,

The exam is organised in three parts. Part 1 has four multiple-choice questions, each question worth five marks. So, in total, 20 marks. All questions have only one correct alternative.

Part 2 has three "open" questions. Each question has four items, each worth five marks. So, 20 marks per question and a total of 60 marks for part 2. These are questions that you need to provide a textual answer.

Part 3 has two programming questions, 20 marks each. You need to write Python code for them. Expect to write around 15 lines of code for each question.

The exam is a Jupyter notebook. We will have the tutorials (theory and practice) and the slides available in the exam environment. The Python installation has the libraries we used in the tutorials. The environment also has a calculator.

We tried to have an exam that covers all the topics. Unfortunately, there are restrictions of time and space. I can tell there are no specific questions about week ten lecture, Bayesian learning. I think all other major topics are represented.

Exam allocation and notes

Posted by Gustavo Batista Monday 02 December 2019, 12:49:43 PM.

All,

As you may know, the COMP9418 exam will be on 12th December. Please, check the seating allocation in the following URL:

http://cgi.cse.unsw.edu.au/~cs9418/19T3/seating/final/register.cgi/allocations

The exam will consist of quick questions (suck as multiple choice), open and programming problems. The exam will take place in the CSE labs, and we will provide a Python notebook. All questions will be answered in the notebook, and you should use markdown cells to write formulas and tables and code cells for programming exercises.

You are allowed to bring notes to the exam. You can bring any material you want as long as it is printed. The idea is that you do not have to memorize anything to do the exam.

Gustavo.

Sampling from conditional distribution in Gibbs sampling

Posted by Gustavo Batista Saturday 16 November 2019, 11:39:26 AM.

Hi all,

during the last consultation, the students told me they were using VE to compute the conditional distribution in Gibbs sampling. That will be computationally expensive and, as a consequence, it may force us to sample less from the chain.

I would like to call your attention to the following result. It was already in the lecture slides, but I hope, this new slide will help to implement it in your code.

Please, notice all probabilities here involve instantiated variables from network families, so they can be taken directly from the CPTs.

Gustavo.

Assignment1 deadline is now shifted to Sat 12 Oct 23:59:00.

Posted by Armin Chitizadeh Monday 14 October 2019, 12:44:35 PM, last modified Monday 14 October 2019, 12:45:55 PM.

Hi all,

Good news!

Due to some submission issues for assignment1, we have decided to shift the deadline to Sat 12 Oct 23:59:00 . This means if you have submitted before this time you will not be penalised. You do not need to do anything , the system recalculated the possible penalty, if there is any, for your submission automatically.

For the future assignments, first, read the specs and deadline time carefully. Second, try to submit at least a few hours before the deadline. CSE servers might crash close to the deadline as several students are trying to submit for several courses.

Cheers,
Armin

Quiz2 is out now
