Method Detail

add

public void add(FeatureVector fv)

Adds all indices that are present in some other feature vector with value 1.0. Beware that this may have unintended effects if fv.dictionary != this.dictionary

add

public void add(FeatureVector fv,
                String prefix)

Adds all features from some other feature vector with weight 1.0. The names of the added features are generated by adding a prefix to their names in the original feature vector. This does not require that fv.dictionary != this.dictionary.

Parameters:

fv - A feature vector to add from. Its feature names must be Strings.

prefix - String to add when generating new feature names

add

public void add(FeatureVector fv,
                String prefix,
                boolean binary)

Adds all features from some other feature vector with weight 1.0. The names of the added features are generated by adding a prefix to their names in the original feature vector. This does not require that fv.dictionary != this.dictionary.

Parameters:

fv - A feature vector to add from. Its feature names must be Strings.

prefix - String to add when generating new feature names

binary - true if fv is binary
