COMP5329 - Deep Learning

Assignment-1

Due: Thursday, 13 April (Week 7)

1. Task description

Based on the codes given in Tutorial: Multilayer Neural Network, you are required to accomplish a multi-class

classification task on the provided dataset.

In this assignment, you are expected to implement the modules specified in the marking table.

You must guarantee that the submitted codes are self-complete, and the newly implemented modules can be

successfully run in common python environment.

You are NOT allowed to use Deep Learning frameworks (e.g. PyTorch, Tensorflow, Caffe, and KERAS), or

any kinds of auto-grad tools (e.g. autograd).

Scientific computing packages, such as NumPy and SciPy, are acceptable.

If you have any question about the assignment, please contact: Mr Jinxu Lin [email protected]

Dataset

The dataset can be downloaded from Canvas. There are 10 classes in this dataset. The dataset has been splited

into training set and test set.

2. Instructions to hand in the assignment

2.1 Go to Canvas and upload the report. The report should include each member’s details (student ID and

name).

If you work as a group, only one student needs to submit the report which must be named as student ID

numbers of all group members separated by underscores. E.g. “xxxxxxxx_xxxxxxxx_xxxxxxxx.pdf”

2.2 The report must include a link of your code and data (e.g., a shared Google cloud folder, so we can

easily run it on Colab). Clearly provide instructions on how to run your code in the appendix of the report

or include a readme.txt in your shared folder.

Don’t update the code/data any more after the submission. If the latest modified time of the shared folder

is signiftanly late after the submisison deadline, the whole submission will be taken as a late submission.

2.3 The report must clearly show (i) details of your modules, (ii) the predicted results from your classifier

on test examples, (iii) run-time, and (iv) hardware and software specifications of the computer that you

used for performance evaluations.

2.4 There is no special format to follow for the report but please make it as clear as possible and similar to a

research paper.

2.5 If you use ChatGPT or other AI tools for the assignments, please clarify how you have used them in the

report.

Late submission:

Suppose you hand in work after the deadline:

If you have not been granted special consideration or arrangements

– A penalty of 5% of the maximum marks will be taken per day (or part) late. After ten days, you will be

awarded a mark of zero.

– e.g. If an assignment is worth 40% of the final mark and you are one hour late submitting, then the maximum

marks possible would be 38%.

– e.g. If an assignment is worth 40% of the final mark and you are 28 hours late submitting, then the maximum

marks possible marks would be 36%.

– Warning: submission sites get very slow near deadlines

– Submit early; you can resubmit if there is time before the deadline.

3. Marking scheme

Category Criterion

Report [50]

Introduction [5]

- What’s the aim of the study?

- Why is the study important?

Methods [15]

- Pre-processing (if any)

- The principle of different modules

- What is the design of your best model?

Experiments and results (with Figures or Tables) [20]

- Performance in terms of

different evaluation metrics.

- Extensive analysis, including hyperparameter analysis, ablation studies and

comparison methods.

- Jusitification on your best model.

Discussion and conclusion [5]

- Meaningful conclusion and reflection

Other [5]

- At the discretion of the marker: for impressing the marker, excelling

expectation, etc. Examples include fast code, using LATEX, etc.
