HashingFunctionParams

Hashing Parameters

hashWithIndex: if true, include indices when hashing a feature that has them (OPLists or OPVectors)
prependFeatureName: if true, prepends a input feature name to each token of that feature
numFeatures: number of features (hashes) to generate
numInputs: number of inputs
maxNumOfFeatures: max number of features (hashes)
binaryFreq: if true, term frequency vector will be binary such that non-zero term counts will be set to 1.0
hashAlgorithm: hash algorithm to use
hashSpaceStrategy: strategy to determine whether to use shared hash space for all included features
