Package com.yahoo.vespa.model.ml

Class ConvertedModel

java.lang.Object
com.yahoo.vespa.model.ml.ConvertedModel
public class ConvertedModel extends Object
A machine learned model imported from the models/ directory in the application package, for a single rank profile. This encapsulates the difference between reading a model - from a file application package, where it is represented by an ImportedModel, and - from a ZK application package, where the models/ directory is unavailable and models are read from generated files stored in file distribution or ZooKeeper.
