@DefaultImplementation(value=DefaultUserVectorNormalizer.class) public interface UserVectorNormalizer
This interface is essentially a user-aware version of
DefaultUserVectorNormalizer, delegates to a
VectorNormalizer. Implement this interface directly to create a normalizer
that is aware of the fact that it is normalizing a user and e.g. uses user properties
outside the vector to aid in the normalization. Otherwise, use a context-sensitive
VectorNormalizer to configure the user vector normalizer:
factory.in(UserVectorNormalizer.class) .bind(VectorNormalizer.class) .to(MeanVarianceNormalizer.class);
|Modifier and Type||Method and Description|
Make a vector transformation for a user.
Normalize a vector with respect to a user vector.
MutableSparseVector normalize(long user, @Nonnull SparseVector vector, @Nullable MutableSparseVector target)
user- The user to normalize a vector for.
vector- The user's vector for reference.
target- The vector to normalize. If
null, the user vector is normalized.
targetvector, if specified. Otherwise, a fresh mutable vector containing a normalized copy of the user vector is returned.
VectorTransformation makeTransformation(long user, SparseVector vector)
user- The user ID to normalize for.
vector- The user's vector to use as the reference vector.
