Uses of ItemSimilarity in org.apache.mahout.cf.taste.impl.similarity
 

Classes in org.apache.mahout.cf.taste.impl.similarity that implement ItemSimilarity
 class AbstractItemSimilarity
           
 class CachingItemSimilarity
          Caches the results from an underlying ItemSimilarity implementation.
 class CityBlockSimilarity
          Implementation of City Block distance (also known as Manhattan distance) - the absolute value of the difference of each direction is summed.
 class EuclideanDistanceSimilarity
           An implementation of a "similarity" based on the Euclidean "distance" between two users X and Y.
 class GenericItemSimilarity
           A "generic" GenericItemSimilarity.ItemItemSimilarity which takes a static list of precomputed item similarities and bases its responses on that alone.
 class LogLikelihoodSimilarity
          See http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.14.5962 and http://tdunning.blogspot.com/2008/03/surprise-and-coincidence.html.

           An implementation of the cosine similarity.
 

Constructors in org.apache.mahout.cf.taste.impl.similarity with parameters of type ItemSimilarity
CachingItemSimilarity(ItemSimilarity similarity, DataModel dataModel)
          Creates this on top of the given ItemSimilarity.
CachingItemSimilarity(ItemSimilarity similarity, int maxCacheSize)
          Creates this on top of the given ItemSimilarity.
GenericItemSimilarity(ItemSimilarity otherSimilarity, DataModel dataModel)
           Builds a list of item-item similarities given an GenericItemSimilarity.ItemItemSimilarity implementation and a DataModel, rather than a list of GenericItemSimilarity.ItemItemSimilaritys.
GenericItemSimilarity(ItemSimilarity otherSimilarity, DataModel dataModel, int maxToKeep)
           Like GenericItemSimilarity.GenericItemSimilarity(ItemSimilarity, DataModel) )}, but will only keep the specified number of similarities from the given DataModel.
 

Uses of ItemSimilarity in org.apache.mahout.cf.taste.impl.similarity.file
 

Classes in org.apache.mahout.cf.taste.impl.similarity.file that implement ItemSimilarity
