Examples of UncenteredCosineSimilarity

org.apache.mahout.cf.taste.impl.similarity.UncenteredCosineSimilarity

An implementation of the cosine similarity. The result is the cosine of the angle formed between the two preference vectors.

Note that this similarity does not "center" its data, shifts the user's preference values so that each of their means is 0. For this behavior, use {@link PearsonCorrelationSimilarity}, which actually is mathematically equivalent for centered data.

  public Track1Recommender(DataModel dataModel) throws TasteException {
    // Change this to whatever you like!
    ItemSimilarity similarity = new UncenteredCosineSimilarity(dataModel);
    recommender = new GenericItemBasedRecommender(dataModel, similarity);
