Class  Description 

AbstractUserVectorNormalizer 
Abstract user vector normalizer implementation.

AbstractVectorNormalizer 
Abstract vector normalizer implementation.

BaselineSubtractingUserVectorNormalizer 
User vector normalizer that subtracts a user's baseline scores.

DefaultItemVectorNormalizer

Default user vector normalizer that delegates to a generic
VectorNormalizer . 
IdentityVectorNormalizer 
Identity normalization (makes no change).

MeanCenteringVectorNormalizer 
Vector normlizer that subtracts the mean from every value.

MeanVarianceNormalizer 
Normalizes against the variance of the vector with optional smoothing as
described in Hofmann '04.

MeanVarianceNormalizer.Builder 
A Builder for UserVarianceNormalizers that computes the variance from a
RatingBuildContext.

UnitVectorNormalizer 
Vector normalizer that scales a vector by the factor needed to scale the
reference vector to a unit vector.
