The terms below describe methods of how scientists have attempted to teach or design machines to learn.

Use www.webopedia.com to define the following:

• Agent - as it relates to artificial intelligence
• Parallel processing
• Pattern recognition
• Machine learning
• Inference rules - use http://foldoc.doc.ic.ac.uk/

A situation in which fuzzy logic can be used is demonstrated at the following website.

Visit http://www.clarkson.edu/~esazonov/neural_fuzzy/loadsway/LoadSway.htm

Try both manual and fuzzy control of getting the load from the ship to the dock. These controls can be selected by clicking on the buttons underneath the simulation of the ship and dock.

1. Explain which method causes the least sway (movement forwards and backwards) at the fastest speed of the box being loaded/unloaded from the ship. (2 marks)

2. What kind of knowledge (linguistic variables) is needed here? Hint: have a look at the boxes and graph underneath the simulation. (3 marks)

3. Explain the kind of inference rules might be used here? Hint: look at the text box. (2 marks)

4. Explain why fuzzy logic may be used for this situation. (3 marks)
