Constructor Detail

AbstractSimilarityCache

protected AbstractSimilarityCache(WriteableObjectPool pool,
                                  T similarityMatrix,
                                  String pathCache,
                                  SimCalculatorStrategy strategy,
                                  boolean complete)

Creates an abstract similarity cache. It computes similarities between all cases of the pool according to the given strategy and stores them in the similarity matrix. The given path is checked if it contains some or all of the similarities to compute (depending on the value of the parameter complete).

Parameters:

pool - the pool to take the queries and cases from

similarityMatrix - the similarity matrix to store the similarities in

pathCache - the path to store the cache and load it from, respectively

strategy - the strategy to compute the similarities with

complete - whether to complete the computations in the loaded file or start from scratch

AbstractSimilarityCache

                                  SimCalculatorStrategy strategy,
                                  boolean complete)

Creates an abstract similarity cache. It computes similarities between all cases of the pool according to the given strategy and stores them in the similarity matrix. The given path is checked if it contains some or all of the similarities to compute (depending on the value of the parameter complete).

Parameters:

queryPool - the pool to take the queries from

casePool - the pool to take the cases from

similarityMatrix - the similarity matrix to store the similarities in

pathCache - the path to store the cache and load it from, respectively

strategy - the strategy to compute the similarities with

complete - whether to complete the computations in the loaded file or start from scratch
