Neural Networks

COSC420 - Neural Networks

Semester 1, 2018 (The Guide to Enrolment 2018 incorrectly says this paper is not offered in 2018)

Hi, and welcome to COSC420 in 2018.  It's a very interesting time for neural networks right now, with huge strides in theory, performance, and commercial application. Salaries in some cases are going crazy. If you haven't seen it before, here is the standard course overview:

Despite its slow "hardware", the brain is a much more powerful and sophisticated computational system than any computer ever built. What can the brain teach us about computation and how to perform complex tasks such as natural language processing, vision, and control and optimisation problems? Artificial neural networks are a family of methods that try to address these issues and explore "brain-like" computation, information processing and learning. "Deep learning" is a currently popular technology based on convolutional neural networks, and used by organisations such as Google, Baidu, Microsoft and Apple.

This paper will cover an introduction to neural networks, a survey of algorithms and architectures (including deep learning), and practical applications of neural networks. Depending on student interest we may also cover the impact of neural networks in other fields (such as psychology, neuroscience, parallel computers), or related topics such as artificial life, software agents, and robotics.

COSC420 is good preparation, but is not required, for COSC421 and COSC422.


Lectures are held in Owheo G34, Tuesday 11am-1pm. The lecturer is Anthony Robins Owheo 2.53, phone 479-8314, email


• Assignment: 25%, due date is TBA (by email to me), note departmental policy -10% per working day if late.

• Presentation and reviews: 10%, due date TBA (varies by student)

• Quizzes and participation: 5%

• Final exam: 60% - date and venue to be arranged.


The content of the course is fairly fluid this year, and can be influenced by student interests! We will start out by introducing the basics and the practical use of neural nets. We then look at important architectures such as 1-layer nets, multi-layer nets (back propagation), deep / convolutional nets, Hopfield nets, self organising maps, recurrent nets and more.

Then we can choose from a range of topics, determined by student interest. Possibilities include:

  • deep learning (convolutional neural networks)
  • neural nets and the brain ("real neuroscience")
  • neural nets and cognition (models of memory, learning, language etc.)
  • parallel hardware implementations ("neurocomputers")
  • catastrophic forgetting and ongoing learning (my own research)
  • neural network and symbolic hybrids (e.g. nets and decision trees)
  • mathematical and Baysean interpretations
  • practical applications of neural nets
  • artificial life / software agents
  • robotics / vision
  • other - suggest your own!

Lecture notes and readings

The Department has gone "paperless" so lecture notes and readings are distributed in pdf form via email. There is no set text book. The books below will be referred to - often using the [abbreviation]. Readings for each lecture will be taken from various sources. The following texts are of historical interest.
