List of dataset() Examples

Examples of dataset()

weka.core.DenseInstance.dataset()
weka.core.Instance.dataset()
Returns the dataset this instance has access to. (ie. obtains information about attribute types from) Null if the instance doesn't have access to a dataset. @return the dataset the instance has accesss to
weka.core.Instances.dataset()
