Uses of PreferenceArray in org.apache.mahout.cf.taste.impl.model |
---|
Classes in org.apache.mahout.cf.taste.impl.model that implement PreferenceArray | |
---|---|
class |
BooleanItemPreferenceArray
Like BooleanUserPreferenceArray but stores preferences for one item (all item IDs the same) rather
than one user. |
class |
BooleanUserPreferenceArray
Like GenericUserPreferenceArray but stores, conceptually, BooleanPreference objects which
have no associated preference value. |
class |
GenericItemPreferenceArray
Like GenericUserPreferenceArray but stores preferences for one item (all item IDs the same) rather
than one user. |
class |
GenericUserPreferenceArray
This implementation maintains two parallel arrays, of user IDs and values. |
