Méthode Description
ComputeMappingFit ( ) : double[]
MapUserToLatentFactorSpace ( ICollection user_attributes ) : double[]

map from user attributes to latent factor space
SampleUserWithAttributes ( ) : int

Samples an user for the mapping training. Only users that are associated with at least one item, and that actually have attributes, are taken into account.
