why are class labels in data partitions useful what is the class label partition of x data is partitioning valid which of the following is a characteristic of a partitioning algorithm? when a class label is in a data data partition why are class labels in partitioned data why is x in training set not in training why label x in a training set what happens when the class labels appear in the training set? why use class labels in data partitioning can a data partition contain all label labels does a training set contain class labels which label appears in only one training set and not in the training sets and partitions why do you partition data what is the purpose of a class label partition? why is it useful which partition does an algorithm partition which partitioning algorithm can use class labels what is the purpose of a class label in a training set which class labels are not present in the training set and not in the training set? what is a class label in a data partition
