List of attributeSparse() Examples

Examples of attributeSparse()

weka.core.Instance.attributeSparse()
Returns the attribute with the given index. Does the same thing as attribute(). @param indexOfIndex the index of the attribute's index @return the attribute at the given position @throws UnassignedDatasetException if instance doesn't have access to adataset
