Implementation of Leave one out cross-validation on the base of CCrossValidationSplitting. Produces subset index sets consisting of one element,for each label.
Definition at line 22 of file LOOCrossValidationSplitting.h.
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.
- Parameters
-
dict | dictionary of parameters to be built. |
Definition at line 597 of file SGObject.cpp.
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.
- Returns
- 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
Definition at line 714 of file SGObject.cpp.
A deep copy. All the instance variables will also be copied.
Definition at line 198 of file SGObject.cpp.
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.
- Parameters
-
other | object to compare with |
accuracy | accuracy to use for comparison (optional) |
tolerant | allows linient check on float equality (within accuracy) |
- Returns
- true if all parameters were equal, false if not

generates a newly created SGVector<index_t> with indices of the subset with the desired index
- Parameters
-
subset_idx | subset index of the to be generated vector indices |
- Returns
- newly created vector of subset indices of the specified subset is written here.
Error if there are no index sets
Definition at line 76 of file SplittingStrategy.cpp.
generates a newly created SGVector<index_t> with inverse indices of the subset with the desired index. inverse here means all other indices.
- Parameters
-
subset_idx | subset index of the to be generated inverse indices |
- Returns
- newly created vector of the subset's inverse indices is written here.
Error if there are no index sets

If the SGSerializable is a class template then TRUE will be returned and GENERIC is set to the type of the generic.
- Parameters
-
generic | set to the type of the generic if returning TRUE |
- Returns
- TRUE if a class template.
