Thinking ... Fuzzy!! |
|
"If a field has gendle slope and its type of rocks is permeable and its soil depth is shallow it has low risk of soil erosion." |
|
"No, no... Try again! Use the phraseology of something belonging to a class!" |
|
"If a field has slope that belongs to class "gentle" and its rock belongs to class "permeable " and the depth of its soil belongs to class "shallow", this field belongs to class "low" with respect to its risk to soil erosion." |
|
"...But how do I handle membership functions? " |
|
"Think of the membership function as the "strength" of an association, ie. the strength with which something belongs to a class. And then think of the requirements you have in order to say that the risk to erosion is "low": They all have to be satisfied for your conclusion to be sound. These requirements are like the links of a chain: they all have to be there for the chain to work!" |
