- | Yes. If you select //true// in the "Top Down Multi-Class" option, you must create another node in the same level with a corresponding opposite name, with prefix "n-". For example, if this class name is "MyClass" the opposite class name will be "n-MyClass". Hypothesis discarded by this operator will be classified as "n-MyClass". | + | Yes.

For example, if this class name is "MyClass" the opposite class name will be "n-MyClass". Hypothesis discarded by this operator will be classified as "n-MyClass". Alternatively, you can define a new node name in the input parameter named **Non Class Name**. |

+ | |||
+ | -Read user input shape file. | ||
+ | -Generates the intersection between the loaded shape file polygons and the operator execution area. | ||
+ | -Using the intersection result generates a set of intermediate hypothesis of "MyClass" and the opposite class "n-MyClass", as describe above. | ||
+ | -Apply the user decision rule (using the supplied training set) over the intermediate hypothesis set. | ||
+ | -Generate the output hypothesis from the decision rule result. | ||
