Soyabean Example
- To refresh your memory here is an example:
- Suppose that we have a sick soyabean plant, and we wish to
discover which of a number of known specimens of sick soyabean plants
it is most like.
- Choose (let's say) three characteristics of the leaves that can be
represented as numbers:
- Amount of the leaf that is covered by the discolouration
- Lightness of the discoloured parts of the leaf
- Lightness of the remaining parts of the leaf
- Suppose that the first two cases to be matched are:
case 1: | coverage - 8 | lightnessA - 4 | lightnessB - 6 |
case 2: | coverage - 10 | lightnessA - 7 | lightnessB - 6 |
- Adding a third case: (2, 3, 9)
- Which is more similar?
- To find out whether case 1 is more similar to case 2 or to case 3,
you simply calculate the two distances, and pick the smaller of the
two.
- Now can you think of any other CBR examples
- What would CBR be good for?
