详细描述

Class for managing individual folds in cross-validation.

It is often desired to print/save informations that occur during individual folds in cross-validation, such as indices, parameters of underlying machine etc. This abstract base class might be called from the CCrossValidation class after each fold in order to collect these things. Different implementations then could output the informations, or even store them to make them accessible later. Since is different for every underlying machine, individual sub-classes have to handle this separately. When writing new subclasses, try to make the design as inheritance based as possible, such that future sub-sub-classes can use yours. Note that subclasses only need to implement methods that they need since all methods in this class are already implemented empty, except for num/fold stuff. These number of runs/folds and their current indices are stored since these might be used from many subclasses.

成员函数说明

void build_gradient_parameter_dictionary ( CMap< TParameter *, CSGObject * > *  dict)
inherited

Builds a dictionary of all parameters in SGObject as well of those of SGObjects that are parameters of this object. Dictionary maps parameters to the objects that own them.

参数
dictdictionary of parameters to be built.

在文件 SGObject.cpp597 行定义.

CSGObject * clone ( )
virtualinherited

Creates a clone of the current object. This is done via recursively traversing all parameters, which corresponds to a deep copy. Calling equals on the cloned object always returns true although none of the memory of both objects overlaps.

返回
an identical copy of the given object, which is disjoint in memory. NULL if the clone fails. Note that the returned object is SG_REF'ed

在文件 SGObject.cpp714 行定义.

CSGObject * deep_copy ( ) const
virtualinherited

A deep copy. All the instance variables will also be copied.

bool equals ( CSGObject other,
float64_t  accuracy = 0.0,
bool  tolerant = false 
)
virtualinherited

Recursively compares the current SGObject to another one. Compares all registered numerical parameters, recursion upon complex (SGObject) parameters. Does not compare pointers!

May be overwritten but please do with care! Should not be necessary in most cases.

参数
otherobject to compare with
accuracyaccuracy to use for comparison (optional)
