LabelType
- The type of the labels in the DatasetFeatureType
- The type of the features in the Datasetpublic class BasicDatum<LabelType,FeatureType>
Basic implementation of Datum interface that can be constructed with a Collection of features and one more more labels. The features must be specified at construction, but the labels can be set and/or changed later.
