Aims

Learning objectives of this assignment:

I a self-selected task to extend aspects of the course material
I involves practical aspects of the machine learning problem, i.e.

I implementing or modifying algorithms and/or
I experimental evaluation of algorithms on data set(s)

I exercise written communication skills in motivating, recording
and summarising work done on a specified task

Submission

The hand-in for this assignment has two parts:
I files containing program code to do something interesting with

data set(s) and/or results of running programs on data set(s)
I compressed archive of files
I any programming language can be used
I must be combined into a single tar or zip archive.

I a report on what you did.
I must be a single document in PDF format.
I must include names and zIDs of ALL team members

Note: ONLY ONE person on the team submits both parts of the
assignment.

Note: Be sure to submit a single PDF file containing your
report, and a single tar/zip file containing other files. DO
NOT combine your PDF with your tar file.

Marking

Total: 30 marks available

I Part 1: [15 marks]

I 8 marks: solving the basic problem as described in the topic
I 7 marks: extra features, or 1 person solving most or all of a

> 1 person problem [at grader’s discretion]

I Part 2: [10 marks]

I 6 marks: describing the problem and your solution
I 4 marks: good presentation and communication of results

I Achievement: [5 marks] At the discretion of the grader –
basically a score based on how impressive the work is based on
the group size, difficulty of the topic, depth of the analysis,
etc.

Part 1

Marks will be gained by:

I evidence of good design or planning by breaking down the
problem into sub-components

I rigorous collection of results

I use of comments and notes to record decisions taken and
reasons for them in the process of the work

I Motivating the choice of project and your approach (e.g. why
was the project interesting? has it been done before? what is
different about your approach?)

Part 1

Marks will be lost by:

I programs failing to compile or run

I missing results files

I no clear information on contents of files submitted (e.g. in
README)

I evidence of plagiarism (including submissions that are very
similar to existing implementations online). This includes
recycling work done for other courses, for example,
COMP9444.

Part 2

Marks will be gained by:

I evidence of thorough testing of an idea

I good presentation and summary of key results using tables,
graphs, etc.

I simple, clear and relevant explanations

I well-formatted, well-organised, spell-checked and
grammar-checked documents

Part 2

Marks will be lost by:

I inappropriate length (aim for length of 3 + 2.5x where x is the
number of group members. Extra figures, tables, etc. can go
in an appendix of reasonable length). This is not a hard
cut-off, and longer reports are OK so long as the length is
justified (i.e., the content is crucial to the report, use your
best judgement).

I digression, rambling or waffling to fill space unnecessarily
I errors or inconsistencies in presentation, such as

I incorrect description of algorithms or their properties
I poor algorithm selection for a task
I errors in evaluation, like not using an independent test set or

cross-validation if this is required
I statements or conclusions not based either on your

experimental results or referenced sources
I incorrect or inappropriate use of statistical tests

I evidence of plagiarism

Group Configuration

Each team must be configured with 1-5 students currently
enrolled in the course

I Teams can be made up of students from different tutorials,
and groups can consist of both PG and UG students.

I Larger teams are expected to do more (achievement grade will
be affected by this)

I Teams should submit a summary of work completed by each
member. If missing, we will assume that all members
contributed equally.

I You can use the Moodle Group Project (finding a group)
Forum to find group members if needed.

I Add your group to the ‘Group Project – Member
Selection’ object on Moodle. Deadline to do this is
Friday 2 July 2021. You can only join a group if you
have the permission of the other group members!

Member Contributions

I All group members should contribute equally to any work
submitted.

I In the case the group feels that one or more of the students
have not contributed sufficiently, we will take steps to
re-distribute the marks accordingly.

I Some good advice: Keep a record of your contributions
throughout the project. Keep a record of all communications
with other group members (emails/chat), etc. In the event of
a group dispute, we will request evidence from all group
members about contribution. Failure to produce evidence
means that all group members will receive the same grade.

Report Structure

Giving a very strict set of guidelines to the format of the report for
the project is difficult since the different projects are very varied.
However, some things to keep in mind are:

I Length: Keep it concise. Include a README file with the
code so you don’t have to put that type of information in the
report.

I Introduction: You must explain the problem you have
tackled, the basic approach taken to solving it, why you chose
it, and any important aspects of that approach in terms of
machine learning.

I Implementation: If your work was mostly implementation,
focus on that. Otherwise briefly describe what you did.

Report Structure

I Experimentation: All methods must be tested on some data,
so these results should be included. Additionally, if this was a
major focus, you will need to explain the work done and what
was accomplished, for example on setting up the learning
task, choice of evaluation, and so on. Detailed statistical
analyses are probably outwith the scope of the project, so
don’t include these unless you are already very familiar with
this kind of thing.

I References: Should be there for algorithms used or other
aspects of the work.

I Appendix: Should be used if you have a lot of experimental
results. However, consider plotting graphs or using other
visualizations like histograms to summarize a lot of results
concisely.

Deadline

Sunday August 1st, 2021 23:59:59

Topics: Topic 0 – Propose your own

The objective of this topic is to propose a machine learning
problem, source the dataset(s) and implement a method to solve
it. This will typically come from an area of work or research of
which you have some previous experience.

I it must involve some practical work with some implementation
of machine learning

I you must send an email to the course admin (use the class
account) with a description of what you are planning (a
couple of paragraphs should be enough) that needs to be
approved in an emailed reply before you start

I it must not involve double-dipping, i.e., be part of project for
another course, or for research postgrads it must include a
statement to the effect that it is not part of the main work
planned for the thesis (although it can be related)

I If you choose to do topic 0, the deadline to propose a project
is 9th July.

Topics: Topic 1 – Machine Learning Paper

The objective of this topic is to choose a journal or conference
paper, summarise its findings, and implement the proposed
algorithm on a new or simulated dataset.

I Good sources for papers are: NeurIPS, ICML, JMLR, JAIR,
ICLR, or ArXiv

I You may also choose a series of papers and compare various
approaches to the same problem.

I Email the course admin before you get started on this one
too. If you choose to do topic 1, the deadline to propose a
project is 9th July.

Topics: Topic 2 – Competitions & Challenges – Kaggle

I Kaggle competitions are hosted here. You may only work on
competitions that are labelled either Featured or Research or
Analytics. You can select one from either Active or
Completed competitions to work on.

I assess carefully the time you will need to understand the
competition requirements, get familiar with the data and run
the algorithm(s) you plan to use

I for live competitions you can include your submission’s placing
on the leaderboard at submission time! Note however, that
your grade will not be determined solely by your leaderboard
ranking. Of course it will be great to do well in the
competition, but we are mainly grading you based on your
approach and final report.

I You do not need admin approval for this topic. You must
include a link to the competition on the first page of your
report. Failure to do so will result in a 2 mark immediate
penalty.

Topics: Other Considerations

I Do not choose a project that needs a significant amount of
data processing, or ’create’ a dataset, as we are primarily
interested in machine learning in this course, not data
cleaning. Of course most tasks will require some
preprocessing.

I A larger group is expected to achieve more, and group size
will be taken into consideration when assigning marks for
achievement and extra features.

I Choose a topic that interests you, but be pragmatic when it
comes to time requirements and difficulty of the project.

I Use common sense when choosing
competitions/datasets/models. Do not expect a good grade if
you choose a very simple task.

I Before using advanced machine learning techniques, always
use a simple baseline such as a decision tree or logistic
regression.

Examples: Project Reports

I Every project is different.

I However, if you follow the guidelines above your group should
be able to produce a good report.

I We have provided two recent reports as examples.

I The first is from last year on a Kaggle competition.

I The second is from a few years ago on an application of
Reinforcement Learning (this topic is no longer available, but
it could give you some ideas for an original topic of your own).

I These are available on the course Moodle page under
the Project object in the ‘Project Examples’ folder.

Examples: Topic 1 – Machine Learning Paper

You don’t have to pick any of the suggestions below, they are just
to give you an idea. They range from quite theoretical to practical.

I A comprehensive look at evaluation.

I Proposal for a new technique called stagewise regression.

I Mathematical analysis of neural network approximation.

I A new Python library for tensor processing.

I A Python library for the important task of outlier detection.

Please discuss carefully with your group if you want to do
this topic, and also search the sources in the Topic 1 slide
above for more options before you make your selection.

Examples: Topic 2 – Competitions and Challenges

Kaggle is a go-to site for machine learning problems and datasets.
These provide an excellent opportunity to acquire the essential
skills for applied machine learning. You don’t have to pick any of
the suggestions below, they are just to give you an idea.

Note: some of the datasets on Kaggle are big — you can
sample a subset of the data for your project, just make sure
that how you do this is detailed in your group’s report.

Some typical prediction tasks:

I Fraud detection.

I Malware prediction.

I Hourly rainfall.
