Assessment and Submission Details
Marks: 40% of the Total Assessment for the Course
Due Date: 11:59pm Friday, Exam Week 1
Submit your assignment to Blackboard Task 3. Please follow the submission instructions in
The assignment will be marked out of a total of 100 marks and forms 40% of the total
assessment for the course. ALL assignments will be checked for plagiarism by SafeAssign
system provided by Blackboard automatically.
Refer to your Course Outline or the Course Web Site for a copy of the “Student Misconduct,
Plagiarism and Collusion” guidelines.
Late submission will be penalised according to the policy in the course outline. Please note
Saturday and Sunday are included in the count of days late.
Requests for an extension to an assignment MUST be made to the course coordinator prior to
the date of submission and requests made on the day of submission or after the submission
date will only be considered in exceptional circumstances. Assignment submission extensions
will only be made using the official University guidelines.

Assignment Task
This assignment consists of two deliverables, being:
• One code implementation (50%). The code file in Jupyter Notebook format and the relevant
data set files should be contained within a folder named: Task 3-Your NameStudent_Number, the folder is then to be zipped and uploaded to blackboard.
• A report (50%). The report must be uploaded as a separate file.
Part I – PySpark source code (50%)
Important Note: For code reproduction, your code must be self-contained. That is, it should
not require other libraries besides PySpark environment we have used in the workshops. The
data files are packaged properly with your code file.
In this component, we need to utilise Python 3 and PySpark to complete the following data
analysis tasks:
1. Exploratory data analysis
2. Recommendation engine
3. Classification
4. Clustering
You need to choose a dataset from Kaggle (https://www.kaggle.com/datasets) to complete
these tasks. Remember to include the data set file in you source code submission.
Note: In your notebook, please use Heading 1 Markdown cell to separate each sub task.
Task I.1: Exploratory data analysis
This subtask requires you to explore your dataset by
• telling its number of rows and columns,
• doing the data cleaning (missing values or duplicated records) if necessary
• selecting 3 columns, and drawing 1 plot (e.g. bar chart, histogram, boxplot, etc.) for each to
summarise it
Task I.2: Recommendation engine
This subtask requires you to implement a recommender system on Collaborative filtering
with Alternative Least Squares Algorithm. You need to include
• Model training and predictions
• Model evaluation using MSE
Task I.3: Classification
This subtask requires you to implement a classification system with Logistic regression with
LogisticRegressionWithLBFGS class. You need to include

• Logistic Regression model training
• Model evaluation
Task I.4: Clustering
This subtask requires you to implement a clustering system with K-means. You need to
• Model training
• Model evaluation
Part II –Report (50%)
You are required to write a report to explain your design and implementation of the machine
learning parts in your code, including the following topics:
• Introduction/summary/explanation to the ML algorithm/concepts
• The learning settings, such as how to prepare training/testing set, what are the key
parameters and how you set them up
• Comments/evaluation for the models learnt
Your report should use the following template:
Table of Contents
1.0 Introduction
Explain the data set you’ve chosen, including its source URL. Demonstrate your
exploratory data analysis in this section.
2.0 Machine learning implementation
2.1 Collaborative filtering
2.3 Logistic regression
2.4 K-Means
3.0 Conclusion
The marking rubrics are viewable on the blackboard.
Report Format
Your report should be about 1000 words, but no more than 1500 words.
The report MUST be formatted using the following guidelines:
• Title Page – Must not contain headers, footers, or page numbering. Include your name
as the report’s author.
• Header – Report title

• Footer – your name and the page number
• Paragraph text – 12 point Calibri single line spacing
• Headings – Arial in an appropriate type size
• Margins – 2.5cm on all margins
• Page numbering
• Introduction and onwards to use conventional numerals (1, 2, 3, 4) starting at
page 1 from the introduction.
• The report is to be created as a single Microsoft Word document (version 2007 or
later). No other format is acceptable and doing so will result in the deduction of
Please follow the conventions detailed in:
Summers, J. & Smith, B., 2014, Communication Skills Handbook, 4th Ed, Wiley, Australia.
The report is to include (at least 5) appropriate references and these references should follow
the Harvard method of referencing. Note that ALL references should be from journal articles,
conference papers, technical papers or a recognized expert in the field. DO NOT use
Wikipedia as a reference. The use of unqualified references will result in the deduction of
Assignment Return and Release of Grades
Assignment grades will be available on the blackboard in two weeks after the submission.
Details of marking will also be accessible via online rubrics on the blackboard.
Where an assignment is undergoing investigation for alleged plagiarism or collusion the
grade for the assignment and the assignment will be withheld until the investigation has
Assignment Advice
This assignment will take several weeks to complete and will require a good understanding of
machine learning and PySpark for successful completion. It is imperative that students take
heed of the following points in relation to doing this assignment:
1. Ensure that you clearly understand the requirements for the assignment – what must be
done and what are the deliverables.
2. If you do not understand any of the assignment requirements – Please ASK your tutor.
3. Each time you work on any aspect of the assignment reread the assignment requirements to
ensure that what is required is clearly understood.
4. We have practiced nearly all coding tasks in DataCamp before. If you have any difficulty,
redoing the practices in DataCamp is recommended.

5. Prior to submitting your code, you should ensure not only that it executes as required, but
also looks professional. It is expected that you adhere to python standards for naming and
indenting. All methods should be adequately documented such that another programmer
examining your code will readily know what the code is doing.
Plagiarism and Collusion Advice
1. All work must be submitted through SafeAssign.
2. SafeAssign will pick up any similarities between work online as well as work from other
students (in this semester and previous)
3. Please make sure you reference your work properly. If you are using any material from the
internet or any books from the library, you need to cite the work correctly. Failure to do so
will result in possible cases of Academic Misconduct.
4. Please do not share your work with other students. Do not give anyone your files to have a
look. SafeAssign will pick up collusion, but keep in mind the percentages for Collusion may
not report accurately until all student assignments have been submitted. Both the person
copying and the person providing will potentially be held accountable.
5. You can submit a draft assignment through SafeAssign before making the actual submission.
