The Power type exposes the following members.

Constructors

	Name	Description

Properties

	Name	Description
	Degree	Gets or sets the kernel's degree.

Methods

	Name	Description
	Clone	Creates a new object that is a copy of the current instance.
	Distance	Computes the squared distance in feature space between two points given in input space. (Inherited from KernelBaseTInput.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Function(Double)	Power Kernel Function
	Function(Double, Double)	Power Kernel Function (Overrides KernelBaseTInputFunction(TInput, TInput).)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Extension Methods

	Name	Description
	Distance	Computes the kernel distance for a kernel function even if it doesn't implement the IDistance interface. Can be used to check the proper implementation of the distance function. (Defined by Tools.)
	HasMethod	Checks whether an object implements a method with the given name. (Defined by ExtensionMethods.)
	IsEqual	Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices. (Defined by Matrix.)
	To(Type)	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)
	ToT	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)

Remarks

The Power kernel is also known as the (unrectified) triangular kernel. It is an example of scale-invariant kernel (Sahbi and Fleuret, 2004) and is also only conditionally positive definite.
