This module introduces the basic concepts and techniques of neural computation, and its relation to automated learning in computing machines more generally. It covers the main types of formal neuron and their relation to neurobiology, showing how to construct large neural networks and study their learning and generalization abilities in the context of practical applications. The Level 4/M version also provides practical experience of designing and implementing a neural network for a real world application.
Here's an outline of the module structure and lecture timetable. All the module handouts will be made available here as pdf files shortly before the paper versions are distributed in the lectures. Any spare paper copies will be deposited in the School library.

For formal details about the aims, learning outcomes and assessment you should look at the official Module Description (Level 4/M or Level 3/H) and Syllabus (Level 4/M or Level 3/H).
The Level 3 module Neural Computation is assessed by 100% Examination.
The Level 4 module Introduction Neural Computation is assessed by 80% Examination and 20% Continuous Assessment.
In both cases the examination will be closed book, and you will be expected to answer all four questions which will each be worth 25% of the total.
A series of Exercise Sheets, largely based on recent examination questions, will give an idea of the standard and type of questions you can expect in this year's examination. These will be distributed when the associated material has been covered in the lectures. They do not contribute to the assessment for the module. They are designed to help you monitor your progress on the module - try to answer the questions without your notes, and then use your notes to see whether your answers are correct. The Exercise Sessions will be used to talk through answers to any questions you have difficulty with. All six Exercise Sheets have now been distributed: Exercise Sheet 1, Exercise Sheet 2, Exercise Sheet 3, Exercise Sheet 4, Exercise Sheet 5 and Exercise Sheet 6.
I have also produced an Equation Sheet which contains the main equations that you should be familiar with from the module.
The Recommended Books for this module are:
|Neural Networks and Learning Machines||Simon Haykin||Pearson, 2009||Very comprehensive, but heavy in mathematics.|
|Neural Networks: A Comprehensive Foundation||Simon Haykin||Prentice Hall, 1999||Older edition of the above book, but still covers the whole module.|
|Neural Networks for Pattern Recognition||Christopher Bishop||Clarendon Press, Oxford, 1995||This is the book I always use, but it doesn't cover the whole module.|
|The Essence of Neural Networks||Robert Callan||Prentice Hall Europe, 1999||Concise introductory text.|
|An Introduction to Neural Networks||Kevin Gurney||Routledge, 1997||Non-mathematical introduction.|
|Fundamentals of Neural Networks||Laurene Fausett||Prentice Hall, 1994||Good intermediate text.|
|Introduction to Neural Networks||R. Beale & T. Jackson||IOP Publishing, 1990||Introductory text.|
|An Introduction to the Theory of Neural Computation||J. Hertz, A. Krogh & R.G. Palmer||Addison Wesley, 1991||Good all round book. Slightly mathematical.|
|Principles of Neurocomputing for Science and Engineering||F. M. Ham & I. Kostanic||McGraw Hill, 2001||Good advanced book, but rather mathematical.|
If you can only afford to buy one book for this module, I would recommend getting either of the Haykin books.
If you want to find online information about Neural Networks, probably the best places to start are: The Neural Networks FAQ web-site, and the Neural Network Resources web-site, both of which are a little old now, but still contain a large range of information and links about all aspects of neural networks.
Potentially useful web-sites for related past modules are still available:
Peter Tino's web-site for this module in 2007
John Bullinaria's web-site for a Level 2 version of this module in 2004
When programming your own MLP neural networks, it may be useful to start with my
Step by Step Guide to Implementing a Simple Neural Network in C.
It should be fairly straightforward to see how to use it with related programming languages such as C++ and Java.
