1. Outline
In this project, we will continue from our Project 1 where we implemented a malicious credit card transaction
detection system. But instead of implementing the features (which we completed in Project 1), we will now
focus on data analysis and visualisation skills to better present what our datasets contain. For this project, you
will be given a dataset (CreditCard_2024_Project2.csv) that contain credit card transactions that are
already labelled normal or malicious. Your task is to perform the following steps (more details in the tasks
section):
Data analysis
Data visualisation
Write data analysis and visualisation report
(bonus) use machine learning to implement detection
Note 1: This is an individual project, so please refrain from sharing your code or files with others. However,
you can have high-level discussions about the syntax of the formula or the use of modules with other examples.
Please note that if it is discovered that you have submitted work that is not your own, you may face penalties. It
is also important to keep in mind that ChatGPT and other similar tools are limited in their ability to generate
outputs, and it is easy to detect if you use their outputs without understanding the underlying principles. The
main goal of this project is to demonstrate your understanding of programming principles and how they can be
applied in practical contexts.
Note 2: you do not necessarily have to complete project 1 to do this project, as it is more about data analysis and
visualisation of the datasets you are given.
2. Tasks
To begin, you need to define a main(filename, filter_value, type_of_card) function that will
read the dataset and store the transaction records in data and call the below functions to display appropriate
results.
Sample Input:
main('CreditCard_2024_Project2.csv', 'Port Lincoln', 'ANZ')
Task 1: Data Analysis using NumPy Mark: 15
Answer the following 5 NumPy related tasks for data analysis. These will require use of NumPy functions and
methods, matrix manipulations, vectorized computations, NumPy statistics, NumPy where function, etc. To
complete this task, write a function called task1(data, filter_value, type_of_card), where
