Method Detail

generateRuns

void generateRuns(String corpusName,
                  String splitName,
                  String query,
                  int nFolds,
                  int nMinPerClass,
                  Integer nSeed,
                  int nRuns)

Generate cross validation folds, store in database.

Parameters:

corpusName - class label

query - query to get instance id - label - class triples

nFolds - number of folds to generate

nMinPerClass - minimum number of instances of each class per fold

nSeed - random number seed; if null will be set currentTime in millis

nRuns - number of runs

Generate cross validation folds, don't store in database.

Parameters:

labelToInstanceMap - an instance class map without folds @see InstanceData.labelToInstanceMap

nFolds - number of folds

nMinPerClass - minimum instance per class

nSeed - random seed default to System.currentTimeMillis()

nRuns - number of runs

foldMap - same structure as labelToInstanceMap, but with folds
