FunkSVDItemScorer

@Inject
public FunkSVDItemScorer(FunkSVDModel model,
                                  @BaselineScorer
                                  org.lenskit.api.ItemScorer baseline,
                                  @Nullable
                                  org.lenskit.data.ratings.PreferenceDomain dom)

Construct the item scorer.

Parameters:

model - The model.

baseline - The baseline scorer. Be very careful when configuring a different baseline at runtime than at model-build time; such a configuration is unlikely to perform well.

dom - The preference domain.
