# STATS 784 : Statistical Data Mining

## Science

### Course Prescription

Data cleaning, missing values, data warehouses, security, fraud detection, meta-analysis, and statistical techniques for data mining such as regression and decision trees, modern and semiparametric regression, neural networks, statistical approaches to the classification problem.

### Course Overview

This course was the first in the department on data mining and was (and still is) intended to be both practical and theoretical. Anybody wanting to use R for regression or classification on big data sets should benefit, as well as research students. So we will look at some statistical theory and practical aspects of data mining. This provides an opportunity to encounter some trendy methods such as random forests. It will have a significant coursework component, most of it being computer work. I may try let you work with at least one `large' data set, and there may be some R programming. Students are required to have  a good background in statistics---both theoretically and computationally (R).

### Course Requirements

Prerequisite: 15 points from STATS 210, 225, and 15 points from STATS 330, 762

### Capabilities Developed in this Course

 Capability 1: Disciplinary Knowledge and Practice Capability 2: Critical Thinking Capability 3: Solution Seeking Capability 4: Communication and Engagement

### Learning Outcomes

By the end of this course, students will be able to:
1. Master fundamental material such as the binary prefixes, big-Oh, and appreciate the role of data science in society. (Capability 1 and 4)
2. Critically evaluate and explain fundamental statistical concepts such as under- and over-fitting, parametric and nonparametric methods, and the curse of dimensionality, within the context of BigData. (Capability 2, 3 and 4)
3. Competently be able to fit 2 or 3 methods well, such as decision trees and generalized additive models. (Capability 2, 3 and 4)
4. Use R efficiently to solve BigData problems, including graphics. (Capability 1, 3 and 4)

### Key Topics

• What is data mining?
• Handling large data sets in R and Linux
• Data visualization
• Decision trees
• VGLMs and VGAMs (especially for estimation and prediction)
• The classification problem (time allowing)
• Compared to previously, I hope to cover the following new topics: variable selection via the lasso, dimension-reduction, random forests, gradient boosting.

### Special Requirements

There is no plussage. Students should complete the assignments, test and exams as best they can. Attendance of lectures are expected. Lecture recordings will be placed on Canvas.

This course is a standard 15 point course and students are expected to spend 150 hours per semester involved in each 15 point course that they are enrolled in. For this course you can expect 3 hours of lectures, a 1-hour tutorial, 2 hours of reading and thinking about the content and 5 hours of work on assignments and/or test preparation each week.

### Delivery Mode

#### Campus Experience

This course is available for those who are remote but the course is primarily aimed at those in Auckland. Lectures will be available as recordings and these will be placed on Canvas so overseas students will need fast internet. For those in Auckland, attendance is expected at lectures but no credit is given for this. Other learning activities such as tutorials/labs (if any) will not be available as recordings. The course will not include live online events including tutorials. Attendance on campus is required for the test (if under Alert Level 1) which is scheduled to be during a class time. The activities for the course are scheduled as a standard weekly timetable.

### Learning Resources

A coursebook will be provided on Canvas chapter by chapter as the course progresses... only this material will be examinable. It will be in .pdf format. Suggested reading lists will be given at the end of each chapter but this is very optional. A study guide at lecture 1 will list some optional overall background reading. Past exams and tests will be available but note that the course has evolved over time and the current material covered has changed significantly.

### Student Feedback

During the course Class Representatives in each class can take feedback to the staff responsible for the course and staff-student consultative committees.

At the end of the course students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback.

Your feedback helps to improve the course and its delivery for all students.

### Digital Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

Computers in the lab will be sufficient, however students are welcome to use their own devices.
Students may hand-write their assignments, however using Rmarkdown or equivalent, is probably better.
The lecturer will set up a class webpage to put supplementary material that might be of interest to the class (FYI only).

The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed against online source material using computerised detection mechanisms.

The content and delivery of content in this course are protected by copyright. Material belonging to others may have been used in this course and copied by and solely for the educational purposes of the University under license.
