QBUS6810: Statistical Learning and Data Mining

Semester 2, 2021 [Normal day] - Camperdown/Darlington, Sydney

It is now common for businesses to have access to very rich information data sets, often generated automatically as a by-product of the main institutional activity of a firm or business unit. Data Mining deals with inferring and validating patterns, structures and relationships in data, as a tool to support decisions in the business environment. This unit offers an insight into the main statistical methodologies for the visualization and the analysis of business and market data. It provides the tools necessary to extract information required for specific tasks such as credit scoring, prediction and classification, market segmentation and product positioning. Emphasis is given to business applications of data mining using modern software tools.

Assessment summary

  • Group project: The group project will examine your understanding of the concepts presented in the unit. The assignment task will measure your knowledge of supervised learning methods, your skill in applying and evaluating these methods using Python, and your ability to communicate the results and conclusions in a professional way. The assignment must be done in groups of up to five students. This assignment will help you develop valuable communication and collaboration skills and allow you to contextualise your statistical learning skills on real applied problems.
     
  • In-semester and final exams: the exam questions will test your understanding of the essential characteristics and theoretical properties of the methods covered. They will also test your ability to make informed comparisons of the methods,  correctly interpret and analyse statistical results and to formulate substantive conclusions based on these results. 

Further information for each assessment will be provided on Canvas.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

Use of generative artificial intelligence (AI) and automated writing tools

You may only use generative AI and automated writing tools in assessment tasks if you are permitted to by your unit coordinator. If you do use these tools, you must acknowledge this in your work, either in a footnote or an acknowledgement section. The assessment instructions or unit outline will give guidance of the types of tools that are permitted and how the tools should be used.

Your final submitted work must be your own, original work. You must acknowledge any use of generative AI tools that have been used in the assessment, and any material that forms part of your submission must be appropriately referenced. For guidance on how to acknowledge the use of AI, please refer to the AI in Education Canvas site.

The unapproved use of these tools or unacknowledged use will be considered a breach of the Academic Integrity Policy and penalties may apply.

Studiosity is permitted unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission as detailed on the Learning Hub’s Canvas page.

Outside assessment tasks, generative AI tools may be used to support your learning. The AI in Education Canvas site contains a number of productive ways that students are using AI to improve their learning.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. know the statistical theory required for business data mining and data analysis
  • LO2. identify which statistical tool is most relevant for specific business analytic tasks
  • LO3. identify the advantages and limitations of each method
  • LO4. extract information from large volumes of data readily available from the business environment
  • LO5. obtain and interpret a meaningful analytical result using a software package such as Python
  • LO6. work productively in a team
  • LO7. present and write about findings effectively.

Graduate qualities

The graduate qualities are the qualities and skills that all University of Sydney graduates must demonstrate on successful completion of an award course. As a future Sydney graduate, the set of qualities have been designed to equip you for the contemporary world.

GQ1 Depth of disciplinary expertise

Deep disciplinary expertise is the ability to integrate and rigorously apply knowledge, understanding and skills of a recognised discipline defined by scholarly activity, as well as familiarity with evolving practice of the discipline.

This section outlines changes made to this unit following staff and student reviews.

No changes have been made since this unit was last offered.

Python

Python is a free and open-source general-purpose programming language that will allow us to bring the content of the unit into practice. Currently, Python is the most widely used language for machine learning and data science. It has powerful data manipulation, statistics, machine learning, data visualisation, and scientific libraries. Python is simple to learn and use and is supported by a large community of users in industry and academia.

You can find more information on Canvas.

Jupyter

The tutorials will make extensive use of Jupyter notebooks. A Jupyter Notebook is a web-based interactive document that combines live code, text and figures.  

We recommend JupyterLab as an integrated development environment for working with Jupyter notebooks. 

Cloud computing

Some tools used in this unit of study can have high computational requirements that exceed the capabilities of your current device. You should be ready to use a cloud environment such as Google Colab (free service) to run computationally intensive code as necessary. See Canvas for more options. 

Self-study

Students will be asked to study additional material beyond the lectures and tutorials.

Disclaimer

The University reserves the right to amend units of study or no longer offer certain units, including where there are low enrolment numbers.
