CParameterCombination类 参考

详细描述

Class that holds ONE combination of parameters for a learning machine. The structure is organized as a tree. Every node may hold a name or an instance of a Parameter class. Nodes may have children. The nodes are organized in such way, that every parameter of a model for model selection has one node and sub-parameters are stored in sub-nodes. Using a tree of this class, parameters of models may easily be set. There are these types of nodes:

-root node: no name and no Parameter instance, every tree has such a node as root. Has children.

-Parameter node: a node with no name and an instance of Parameter, filled with one or more values. There may be different elements in these Parameter instances. Parameter nodes may have children with sub-parameters.

Again: Leafs of the tree may only be Parameter nodes.
