0.2.0
Provides functions for transforming an annotation dataset into a standard label dataset using the DawidSkene algorithm.
This algorithm only works with types.MulticlassAnnotation datasets although one can easily use it for types.BinaryAnnotation through Spark Dataset
methodas
It returns a types.DawidSkeneModel with information about the estimation of the true class, as well as the annotator quality and the log-likelihood obtained by the model.
