Assignment 3
Introduction
In this assignment you will be using the Movie dataset provided and the machine learning algorithm you have
learned in this course in order to find out, knowing only things you could know before a film was released ,
what the rating and revenue of the film would be. the rational here is that your client is a movie theater that
would like to decide for how long should they reserve the movie theater to show a movie when it is released.
Datasets
In this assignment you will be given two datasets training.csv (https://github.com/mysilver/COMP9321-Data-
Services/raw/master/20t1/assign3/training.csv) and validation.csv (https://github.com/mysilver/COMP9321-
Data-Services/raw/master/20t1/assign3/validation.csv) .
You can use the training dataset (but not validation) for training machine learning models, and you can use
validation dataset to evaluate your solutions and avoid over-fitting.
Please Note:
This assignment is on the scale of individual small project and hence specifications are deliberately left
open to encourage students to submit innovative solutions.
You can only use Scikit-learn to train your machine learning algorithm
Your model will be evaluated against a third dataset (available for tutors, but not for students)
You must submit your code and a report
Part-I: Regression (10 Marks)
In the first part of the assignment, you are asked to predict the "revenue" of movies based on the the
information in the provided dataset. More specifically, you need to predict the revenue of a movie based on a
subset (or all) of the following attributes (**make sure you DO NOT use rating** ):
cast,crew,budget,genres,homepage,keywords,original_language,original_title,overview,production_companies,
production_countries,release_date,runtime,spoken_languages,status,tagline
Part-II: Classification (10 Marks)
Using the same datasets, you must predict the rating of a movie based on a subset (or all) of the following
attributes (**make sure you DO NOT use revenue** ):
cast,crew,budget,genres,homepage,keywords,original_language,original_title,overview,production_companies,
production_countries,release_date,runtime,spoken_languages,status,tagline

Submission
You must submit two files:
A python script z{id}.py
A report named z{id}.pdf
Python Script and Expected Output files
You code must be executed in CSE machines using the following command with three arguments:
$ python3 z{id}.py path1 path2
path1 : indicates the path for the dataset which should be used for training the model (e.g.,
~/training.csv)
path2 : indicates the path for the dataset which should be used for reporting the performance of the
trained model (e.g., ~/validation.csv); we may use different datasets for evaluation
For example, the following command will train your models for the first part of the assignment and use the
validation dataset to report the performance:
$ python3 YOUR_ZID.py training.csv validation.csv
Your program should create 4 files on the same directory as the script:
z{id}.PART1.summary.csv
z{id}.PART1.output.csv
z{id}.PART2.summary.csv
z{id}.PART2.output.csv
For the the first part of the assignment:
" z{id}.PART1.summary.csv " contains the evaluation metrics (MSR,correlation) for the model trained for the
first part of the assignment. Use the given validation dataset to compute the metrics. The file should be
formatted exactly as follow:
zid,MSR,correlation
YOUR_ZID,6.1,0.7
MSR : the mean_squared_error in the regression problem
correlation : The Pearson correlation coefficient in the regression problem
" z{id}.PART1.output.csv " stores the predicted revenues for all of the movies in the evaluation dataset (not
training dataset) , and the file should be formatted exactly as follow:
movie_id,predicted_revenue
1,7655555
2,75875765
...
For the the second part of the assignment:
" z{id}.PART2.summary.csv " contains the evaluation metrics (average_precision,average_recall,accuracy) for
the model trained for the second part of the assignment. Use the given validation dataset to compute the
metrics. The file should be formatted exactly as follow:

zid,average_precision,average_recall,accuracy
YOUR_ZID,6.1,0.7,89
average_precision : the average precision for all classes in the classification problem
average_recall : the average recall for all classes in the classification problem
" z{id}.PART2.output.csv " stores the predicted ratings for all of the movies in the evaluation dataset (not
training dataset) and it should be formatted exactly as follow:
movie_id,predicted_rating
1,1
2,4
...
Marking Criteria
For EACH of the parts, you will be marked based on:
(3 marks) You code must run and perform the designated tasks on CSE machines without problems
and create the expected files.
(3 marks) How well your model (trained on the training dataset) perform in the test dataset
(2 marks) You must correctly calculate the evaluation metrics (e.g., average_precision) in the output
files (e.g., z{id}.PART2.summary.csv)
(2 marks) One page report containing:
Performance of your model on the validation dataset and how you evaluated the performance
and improved it (e.g., relying on feature selection, switching from one machine leanring model to
a more suitable one,...etc.)
Problems you have faced in predicting (e.g., JOSN formated columns, keywords, missing data)
and how you tried to solve the problem.
Plagiarism
This is an individual assignment . The work you submit must be your own work. Submission of work partially
or completely derived from any other person or jointly written with any other person is not permitted. The
penalties for such offence may include negative marks, automatic failure of the course and possibly other
academic discipline. Assignment submissions will be checked using plagirisim derection tools for both code
and the report and then the submission will be examined manually.
Do not provide or show your assignment work to any other person - apart from the teaching staff of this
course. If you knowingly provide or show your assignment work to another person for any reason, and work
derived from it is submitted, you may be penalized, even if the work was submitted without your knowledge or
consent. Pay attention that is also your duty to protect your code artifacts . if you are using any online
solution to store your code artifacts (e.g., GitHub) then make sure to keep the repository private and do not
share access to anyone.
Reminder: Plagiarism is defined as (https://student.unsw.edu.au/plagiarism) using the words or ideas of others
and presenting them as your own. UNSW and CSE treat plagiarism as academic misconduct, which means
that it carries penalties as severe as being excluded from further study at UNSW. There are several on-line
sources to help you understand what plagiarism is and how it is dealt with at UNSW:
Plagiarism and Academic Integrity (https://student.unsw.edu.au/plagiarism)
UNSW Plagiarism Procedure (https://www.gs.unsw.edu.au/policy/documents/plagiarismprocedure.pdf)

Make sure that you read and understand these. Ignorance is not accepted as an excuse for plagiarism. In
particular, you are also responsible for ensuring that your assignment files are not accessible by anyone but
you by setting the correct permissions in your CSE directory and code repository, if using one (e.g., Github
and similar). Note also that plagiarism includes paying or asking another person to do a piece of work for you
and then submitting it as your own work.
UNSW has an ongoing commitment to fostering a culture of learning informed by academic integrity. All
UNSW staff and students have a responsibility to adhere to this principle of academic integrity. Plagiarism
undermines academic integrity and is not tolerated at UNSW.
