CSequenceLabels类 参考

详细描述

Class CSequenceLabels used e.g. in the application of Structured Output (SO) learning to Hidden Markov Support Vector Machines (HM-SVM). Each of the labels is represented by a sequence of integers. Each label is of type CSequence and all of them are stored in a CDynamicObjectArray.

构造及析构函数说明

default constructor

在文件 SequenceLabels.cpp 第 15 行定义.

CSequenceLabels ( int32_t  num_labels,
int32_t  num_states 
)

standard constructor

参数
num_labelsnumber of labels
num_statesnumber of states

在文件 SequenceLabels.cpp 第 20 行定义.

CSequenceLabels ( SGVector< int32_t >  labels,
int32_t  label_length,
int32_t  num_labels,
int32_t  num_states 
)

constructor using the data of all the labels concatenated. All the labels are assumed to have the same length. The length of labels must be equal to label_length times num_labels.

参数
labelsconcatenation of the labels
label_lengthnumber of elements in each label
num_labelsnumber of labels
num_statesnumber of states

成员函数说明

void add_label ( CStructuredData *  label)
virtualinherited

add a new label to the vector of labels, effectively increasing the number of elements of the structure. This method should be used when inserting labels for the first time.

参数
labellabel to add

被 CMultilabelSOLabels , 以及 CMulticlassSOLabels 重载.

在文件 StructuredLabels.cpp 第 55 行定义.

void add_subset ( SGVector< index_t >  subset)
virtualinherited

Adds a subset of indices on top of the current subsets (possibly subset of subset). Every call causes a new active index vector to be stored. Added subsets can be removed one-by-one. If this is not needed, add_subset_in_place() should be used (does not store intermediate index vectors)

参数
subsetsubset of indices to add

在文件 Labels.cpp 第 39 行定义.

void add_subset_in_place ( SGVector< index_t >  subset)
virtualinherited

Sets/changes latest added subset. This allows to add multiple subsets with in-place memory requirements. They cannot be removed one-by-one afterwards, only the latest active can. If this is needed, use add_subset(). If no subset is active, this just adds.

参数
subsetsubset of indices to replace the latest one with.

在文件 Labels.cpp 第 44 行定义.

void add_vector_label ( SGVector< int32_t >  label)

add a new label to the vector of labels, effectively increasing the number of elements of the structure. This method should be used when inserting labels for the first time. NOTE: the elements of the labels have to be in the interval [0, 1, ..., num_states-1].

参数
labellabel to add

在文件 SequenceLabels.cpp 第 46 行定义.

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

参数
dictdictionary of parameters to be built.

在文件 SGObject.cpp 第 597 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

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)
tolerantallows linient check on float equality (within accuracy)
