score

public abstract double score(java.util.HashMap<java.lang.String,java.lang.Comparable> row)

Score this model on the specified row of data, where the data is specified as a collection of K/V pairs - Values are one of String or Boolean or Number (or subclasses of Number)

score

public abstract double score(int[] MAP,
                             java.lang.String[] SS,
                             double[] DS)

Score this model on the specified row of data, where the data is specified as the members of arrays. MAP is used to map between the SS/DS columns and the columns desired by the Model; this map can be made by a single call to columnMapping. SS/DS hold either String values (for enum/categorical data) or a primitive double. This format exchanges a HashMap lookup for a bare array access, and can be faster (perhaps much faster) for models that are alread quick to score.
