MGRC20007 Machine Learning for data-driven decision making

2024-25 – UG

Unit Assessment Breakdown

This unit uses two modes of assessment, explained in detail below:

Mode	% of unit  mark	Brief Description	Length
Group Assessment	30%	1,500-word report where students work in groups to solve a business problem using machine learning.   They conduct initial data analysis, develop a preliminary model, and create a comprehensive group report.	1,500 words
Individual Assessment	70%	2,000-word report that builds on the group preliminary work. Each student selects a specific aspect of the project to explore in more depth. This could involve refining the model, addressing limitations, or applying  additional analytical techniques to improve the results.	2,000 words

Assessment 1 – Group Project

Link to Unit Learning Outcomes

This assessment evaluates the following unit intended learning outcomes (ILO):

•     ILO1: Demonstrate an understanding of how decisions are made in

organisations, how sustainable development influences business decision- making, and how business analytics can support decision-making.

•     ILO4: Work effectively in a team to develop data-driven recommendations with the potential for a positive impact in practice.

Overview

In the Group Assignment, students are divided into teams to tackle a data analytics project aimed at predicting customer churn for a bank. This assignment evaluates specific learning outcomes (ILO  1 and  ILO 5) by focusing on how teams apply machine learning techniques to solve a real-world business problem and effectively communicate their findings. Each team member contributes to the collaborative process, from data exploration to model development, ensuring a comprehensive understanding of the project and its implications. Collaboratively, they conceptualise and implement the project, applying data mining techniques effectively.

The deliverables for this assignment include:

•     Report (1,500 words): Each team crafts a report similar to a management consultancy   document.   It   outlines   the   project   strategy,   encountered challenges, team reflections, and the outcomes achieved.

Submission

The group report will be submitted on Turnitin, and further details will be provided closer to the time. The due date for the group report and presentation will be 31st October 2024 13:00 GMT.

Assessment 2 – Individual Coursework

Link to Unit Learning Outcomes

This assessment covers the following unit learning objectives:

•    ILO2:  Use  mathematical  tools  to  formulate  decision-making   problems, develop solutions, and provide recommendations based on analytics.

•    ILO3: Design and develop suitable predictive analytics solutions to business decision-making problems within the limits of time and resources available.

•    ILO4: Implement and evaluate a variety of predictive models and improve on their design to meet business needs and requirements.

Assessment Instructions

The purpose of this assessment is to assess your ability to independently apply and extend the machine learning concepts covered in this unit, specifically addressing ILOs 1 and 5. You are required to submit a 2,000-word report that builds on the group  project  by  refining  and  enhancing  the  customer  churn  prediction  model developed in the group work. Your report should demonstrate a deep understanding of the techniques used to improve the model, discuss the ethical considerations involved, and analyse how the refined model can be strategically applied within a real-world banking context. This assignment challenges you to critically evaluate the   model   effectiveness/accuracy,    address   potential    biases,   and   propose actionable business insights based on your findings. We encourage the integration of theoretical knowledge with practical application, reflecting real-world business analytics challenges in an individual context.

Important information about the report

The  report  should  be 2,000  words  (+/-  10%) in  length.  Please  keep  in  mind the following points:

•   This is not an essay assignment. You should not describe or analyse theory and models in isolation. You will be assessed primarily on how you apply the concepts and models from this unit to a real analytics problem, evaluate its effectiveness, identify and recommend improvements that could be made.

•    However, you should include academic references where relevant e.g., the source of models used in your report, supporting data. Please note that you cannot cite the lecture slides! Any quotations from such sources should be properly referenced including page numbers using Harvard referencing style, with full details included in the references section.

•    It is recommended that your work should have between 10 to 20 references. Please use Harvard referencing throughout.

•   Throughout the report, you will need to focus on both the presentation and clarity of any models, diagrams and tables, as well as the quality of your analysis. Consider  how  to  best  present  your  work  to  make  it  look  as professional as possible e.g., using a contents page.

•   Tables and Figures must be labelled with a caption, “Figure 1: Diagram of … .” etc. with the text referring to the Figure, or table, as Figure 1, etc.

•    Reading beyond the course materials is vital.

•   The  use  of  graphs  and  diagrams  to  illustrate  your  analysis  is  strongly encouraged.

•   You are reminded that this assignment is about Business Analytics, not data science nor statistics. The mathematical justification and specific number of analyses you applied is not as important as your ability to conduct a clear analysis of the business implications of those data analytics technique.
