Description
Relief measures the relevance of features by sampling examples and comparing the value of the current feature for the nearest example of the same and of a different class. This version also works for multiple classes and regression data sets. The resulting weights are normalized into the interval between 0 and 1.
Input
- example set: expects: ExampleSet
Output
- weights:

Parameters
- normalize weights: Activates the normalization of all weights.
- number of neighbors: Number of nearest neigbors for relevance calculation.
- sample ratio: Number of examples used for determining the weights.
