Package smile.regression

Record Class SVM.Options

java.lang.Object
java.lang.Record
smile.regression.SVM.Options
Record Components:
eps - the parameter of epsilon-insensitive hinge loss. There is no penalty associated with samples which are predicted within distance epsilon from the actual value. Decreasing epsilon forces closer fitting to the calibration/training data.
C - the soft margin penalty parameter.
tol - the tolerance of convergence test.
Enclosing class:
SVM
public static record SVM.Options(double eps, double C, double tol) extends Record
SVM hyperparameters.

    • toProperties

      public Properties toProperties()
      Returns the persistent set of hyperparameters.
      Returns:
      the persistent set.

    • of

      public static SVM.Options of(Properties props)
      Returns the options from properties.
      Parameters:
      props - the hyperparameters.
      Returns:
      the options.

    • 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

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with '=='.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • eps

      public double eps()
      Returns the value of the eps record component.
      Returns:
      the value of the eps record component

    • C

      public double C()
      Returns the value of the C record component.
      Returns:
      the value of the C record component

    • tol

      public double tol()
      Returns the value of the tol record component.
      Returns:
      the value of the tol record component
