Neural nets are suggestions for the woking of the brain.
It was suggested that, due to a combination of levels and systems, neural nets could perform tasks in the same way that a human brain does, including learning and producing output. Pinker however argued that neural nets could not be an accurate represention of the brain as they were unable to cope with applying rules. The nets are capable of recognising and working with examples that they have already met but they are unable to apply rules to new, unseen examples. For example, humans are able to cope with the rules of grammar. Pinker argued that this ability to recognise and apply special cases was the only quality that hu8mans and neural nets share - because nets are unable to apply the normal rules of grammar or any other example.
