linkinfo-class: Class "linkinfo"

In semisupKernelPCA: Kernel PCA projection, and semi-supervised variant.

Description

Linking Information Class for Kernel Transformation

Objects from the Class

Objects can be created by calls to the function linkinfo.

Slots

link:

Binary matrix containing the link-type contraints,
ie items of the respective kernel matrix should be linked if TRUE.

notlink:

Binary matrix containing the not-link-type contraints

Methods

length

signature(object = "linkinfo"): returns the number of elements associated to the object

add

signature(object = "linkinfo"): adds link or not-link instances in the relations

del

signature(object = "linkinfo"): removes instances from the relations

check

signature(object = "linkinfo"): checks the consistency of the relations

transform

signature(object = "linkinfo"): compute the transitive/composite closures of the relations (see reference)
