Class Model.Parameters

java.lang.Object

water.Iced

hex.Model.Parameters

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, Freezable

Direct Known Subclasses:

SupervisedModel.SupervisedParameters

Enclosing class:

Model<M extends Model<M,P,O>,P extends Model.Parameters,O extends Model.Output>

public abstract static class Model.Parameters
extends Iced

Model-specific parameter class. Each model sub-class contains an instance of one of these containing its builder parameters, with model-specific parameters. E.g. KMeansModel extends Model and has a KMeansParameters extending Model.Parameters; sample parameters include K, whether or not to normalize, max iterations and the initial random seed.

The non-transient fields are input parameters to the model-building process, and are considered "first class citizens" by the front-end - the front-end will cache Parameters (in the browser, in JavaScript, on disk) and rebuild Parameter instances from those caches.
