AIML427 (2023) - Big Data

Prescription

Big Data refers to the large and often complex datasets generated in the modern world: data sources such as commercial customer records, internet transactions, environmental monitoring. This course provides an introduction to the theory and practice of working with Big Data. Students enrolling in this course should be familiar with the basics of machine learning, data mining, statistical modelling and with programming.

Course learning objectives

Students who pass this course should be able to:

  1. Identify properties and challenges of very large data sets in order to determine appropriate analysis techniques to apply a specific Big Data task.
  2. Explain the challenges in high-dimensional data and choose appropriate dimensionality reduction methods, from a software library such as KNIME, to solve high-dimensional problems.
  3. Analyse regression and clustering data to choose appropriate analysis methods with good parameter settings from a software library such as R to generate data visualisations and to address regression and clustering problems.
  4. Use their understanding of tools such as Hadoop MapReduce and Apache Spark to implement relevant algorithmic analysis of Big Data problems using appropriate machine learning libraries.

Course content

This course has critical in-person components, and students are strongly recommended to attend lectures, tutorials and labs on campus. In particular, some assessment items or practical hands-on labs will require in-person attendance, although exceptions can be made under special circumstances.
 
Queries about any such exceptions can be sent to remote-enrolments@ecs.vuw.ac.nz.
 
=============================================
 
Section 1 Introduction to Big Data

  • What is Big Data?
  • Where does Big Data come from? 
  • What we can do and what we should do with Big Data?
  • Typical examples of Big Data analysis in real word
Section 2 Machine learning for high-dimensional data
  • Data Preprocessing and Introduction to Feature Manipulation
  • Machine learning for high-dimensional data, dimensionality reduction and feature selection (and possibly missing data analysis) Wrapper, filter and embedded dimensionality reduction method
  • The techniques covered will include sequential forward selection, sequential backward selection, and other machine learning methods such as decision trees, random forest, support vector machines, genetic programming (and possibly particle swarm optimisation).
Section 3 Regression, Clustering and other Techniques in Big Data
  • Regression: ridge regression, local regression, lasso; the curse of dimensionality
  • Generalized additive models; case study on intelligible models in healthcare applications.
  • Clustering and resampling methods.
Section 4 Big Data Tools/Project 
  • Hadoop MapReduce 
  • Apache Spark
  • Spark Machine Learning Libraries

There are no required texts for this offering.

Mandatory Course Requirements

There are no mandatory course requirements for this course.

If you believe that exceptional circumstances may prevent you from meeting the mandatory course requirements, contact the Course Coordinator for advice as soon as possible.

Assessment

Assessment ItemDue Date or Test DateCLO(s)Percentage
Assignment 1 (25 hours)Monday Week 5CLO: 1,2,320%
Assignment 2 (25 hours)Monday Week 9CLO: 1,2,325%
Test (50 Minutes)Tuesday Week 11CLO: 1,2,325%
Assignment 3 (25 hours)Tuesday Second Week of Assessment PeriodCLO: 430%

Penalties

The penalty for assignments that are handed in late without prior arrangement is one grade reduction per day. Assignments that are more than one week late will not be marked.

Extensions

Individual extensions will only be granted in exceptional personal circumstances, and should be negotiated with the course coordinator before the deadline whenever possible. Documentation (eg, medical certificate) may be requested.

Submission & Return

All work should be submitted through the ECS submission system, accessible through the course web pages. Marks and comments will be returned through the ECS marking system.
 
The School normally has a goal of returning marks for all assessment items within two weeks of the submission deadline. This year, the course will aim to meet this goal, but we expect that sickness and self-isolation due to Covid will extend the time required to mark some assignments and tests.

Workload

In order to maintain satisfactory progress in AIML 427, you should plan to spend an average of at least 10 hours per week on this paper. A plausible and approximate breakdown for these hours would include:

  • Lectures and tutorials: 2
  • Readings: 2-4
  • Assignments: 3-5
However, since this is multidisciplinary course, students with different background may need different amounts of time to work on different sections/assignments of the course,  i.e. could be more or could be less.
