Uses of Hasher in org.tribuo

Methods in org.tribuo with parameters of type Hasher

Modifier and Type	Method	Description
static <T extends Output<T>> ImmutableDataset<T>	ImmutableDataset.hashFeatureMap(Dataset<T> dataset, Hasher hasher)	Creates an immutable shallow copy of the supplied dataset, using the hasher to generate a HashedFeatureMap which transparently maps from the feature name to the hashed variant.
