This assignment specification may be updated to reflect clarifications and modifications after it is first issued. It is strongly suggested that you start working on the assignment right away. You can submit as many times as you like. Only the most recent submission at the due date will be assessed.
In this assignment, you are required to submit a single report in the form of a PDF file. You may also attach supporting information (appendices) as one or more identified sections at the end of the same PDF file. Appendices will not be marked but may be treated as supporting information to your report. Please use a cover sheet at the front that identifies you as author of the work using your u- number and name and identifies this as your submission for COMP8410 Assignment 2. The cover sheet and appendices do not contribute to the page limit or word count.
You are expected to write in a style appropriate to a professional report. You may refer to http://www.anu.edu.au/students/learning-development/writing-assessment/report-writing for some stylistic advice. You are expected to have both an introduction and a conclusion in your report.
No particular layout is specified, but you should follow use no smaller than 11 point typeface and stay within the maximum specified page count. Page margins, heading sizes, paragraph breaks and so forth are not specified but a professional style must be maintained. Text beyond the page limit will be treated as non-existent.
This is a single-person assignment and should be completed on your own. Make certain you carefully reference all the material that you use, although the nature of this assignment suggests few references will be needed. It is unacceptable to cut and paste another author’s work and pass it off

as your own. Anyone found doing this, from whatever source, will get a mark of zero for the assignment and, in addition, CECS procedures for plagiarism will apply.
No particular referencing style is required. However, you are expected to reference conventionally, conveniently, and consistently. References are not included in the page limit. Due to the context in which this assignment is placed, you may refer to the course notes or course software where appropriate (e.g. “For this experiment Rattle was used”), without formal reference to original sources, unless you copy text which always requires a formal reference to the source.
An assessment rubric is provided. The rubric will be used to mark your assignment. You are advised to use it to supplement your understanding of what is expected for the assignment and to direct your effort towards the most rewarding parts of the work.
Your assignment submission will be treated confidentially. It will be available to ANU staff involved in the course for the purposes of marking. It may be shared, de-identified, as an exemplar for other students.
You are to study the supplied data set and to apply data mining processes and techniques to discover interesting things about the data. You are to write a short report that justifies and explains your methods in detail, presents your results, and evaluates and interprets the results you find. In the following, the task is described in terms of what your report should contain, not in terms of the steps you should take to carry out the assignment. In your report, similarly, you should describe the methods used in terms of the language of data mining, not in the terms of commands you typed or buttons you selected.
1. Introduce the problem
You must provide some context to the data mining project you are working on. You could properly refer to the purpose of learning and assessment for COMP8410, but in addition you should set some goals for the exercise – what do you expect to learn from the data? What are you looking for? It is possible that you may not achieve the goals you set here, but it should be possible to trace the results you present back to the goals as motivating questions. Furthermore, you should review the goals you state here in your conclusion.
2. Describe your data
• identify the source of the data and the population over which the data is sampled,
• broadly describe the attributes in the data,
• offer a cursory assessment of data quality, and
• include a basic statistical summary of the data you have.
This should comprise a brief description of the data necessary to explain the context for the work presented here in a self-contained way, although for more detail it might refer to information provided with this assignment specification or elsewhere.
3. Describe your methods
You are encouraged to use Rattle or R for this assignment. You may use external tools instead for
part or all of the work (e.g. you might prefer to use python for data pre-processing). Use of 2

alternative tools may make your explanations of methods more wordy, your methods more difficult to reproduce, and your assignment harder to mark, so take this into account. You will not be awarded marks for methods where your method cannot be understood.
You must use at least two clearly distinct data mining methods as taught in this course. The distinct methods should be diverse regarding: i. different problems like classification, prediction, etc. and ii. different algorithms like NN, DT, etc. You may additionally use multiple other methods taught in this course. Further, you may choose to use some methods not addressed in this course. You must justify your choice of methods with reference to the data types involved, the questions you are looking to answer, the benefit of application to practice, computational feasibility, experimentation experience, or other reasons.
Application of some methods, or addressing particular questions, may require you to pre-process the data in some way. For example, if you are looking to predict outcomes independently of time or political preference, you could consider removing time and political preference attributes from the dataset. You must include either a statement that no such processing was performed or else brief information on any
• removal of provided data from consideration,
• imputation or other transformation, or
• differences in the basic data summary from that you prepared from the original
Data pre-processing can be a never-ending task. Be careful to exercise your judgement on how much you do here, taking account of the marking rubric.
Your description must be sufficient for a reasonably competent professional in the field to reproduce your major results. You may choose to attach detailed specifications or configuration parameters as an appendix (which does not contribute to the word count). If you are using methods that were not taught in the course it would normally be necessary to provide extra detail over that that can be assumed for methods taught in the course. Extended technical detail may be included in an appendix or by well-chosen references that contain enough information to implement the technique.
4. Present your results
You must explain what you found. This should not be a complete listing of everything you found. You should select results that are interesting, surprising, explanatory, answer your initial questions, or are otherwise meaningful, and explain why they are meaningful. Your selected results must be supported by appropriate formal quality measures and must be interpreted within the context of the problem context you gave. Your interpretation must be pitched towards an expert in the field related to the data source and business problem but who may not be an expert in data mining. You might consider using diagrams to assist but use your judgement about any added value of diagrams.
5. Conclude with opportunities for application of your results and identification of further work
Here you should write about the significance of your results and the challenge (or not) of using the results to make changes in the practice for which your data was collected. This analysis should be made in the context of the goals you set in your introduction, and you can afford to speculate about possible impacts of what you found.
You are not expected to be an expert in the area of application, nor to solve challenges you might raise with putting your results into practice. Identifying further work may include identifying

additional data that could be used to refine the results you found, or alternative methods that should be tried with additional resources.

Assessment Rubric
This rubric will be used to mark your assignment. You are advised to use it to supplement your understanding of what is expected for the assignment and to direct your effort towards the most rewarding parts of the work. Your assignment will be marked out of 100, and marks will be scaled back to contribute to the defined weighting for assessment of the course.
