Record Class GaussianProcessRegression.Options

java.lang.Object
java.lang.Record
smile.regression.GaussianProcessRegression.Options
Record Components:
noise - the noise variance, which also works as a regularization parameter.
normalize - the flag if normalize the response variable.
tol - the stopping tolerance for HPO.
maxIter - the maximum number of iterations for HPO. No HPO if maxIter <= 0.
Enclosing class:
GaussianProcessRegression<T>
public static record GaussianProcessRegression.Options(double noise, boolean normalize, double tol, int maxIter) extends Record

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object
