Today we will try to tidy up problems people have with the first 4 labs, and introduce one or two basic improvements.

We can now try out the multi-layer perceptron on some new training sets. To create your own training set try using the following program. Call it by typing [inputs, outputs] = getdata;This will let you try to make 'nasty cases' to test your learning algorithm.

How good is your classification? A little piece of code will give you some results. Download it and type
help confusion for further details. This will help you see how many inputs you are classifying correctly, and where you are making a mistake it will show you which item you are mistaking it with

Direct any queries or difficulties to me rod@dcs.gla.ac.uk - I’ll be pleased to help. Note also that frequently asked questions will appear on the NC4 labs web-page, so check there first.
