class ClassFormatDataSet

Given a DataSet, convert (on-the-fly) targets using a conversion table.

Inheritance:

Public Fields

DataSet* data

The provided DataSet

Sequence* class_labels

The class label translation table

Public Methods

ClassFormatDataSet(DataSet* data_, Sequence* class_labels_)

Here you provide the translation table in class_labels_

ClassFormatDataSet(DataSet* data_, int n_classes=-1)

We assume here that you want the one-hot encoding format.

Inherited from DataSet:

Public Fields

int* selected_examples

int n_inputs

int n_targets

int real_current_example_index

Sequence* inputs

Sequence* targets

int n_examples

int n_real_examples

Public Methods

void init(int n_examples_, int n_inputs_, int n_targets_)

void setExample(int t, bool set_inputs=true, bool set_targets=true)

virtual void setRealExample(int t, bool set_inputs=true, bool set_targets=true)

virtual void pushSubset(int* subset_, int n_examples_)

virtual void popSubset()

virtual void pushExample()

virtual void popExample()

virtual void getNumberOfFrames(int t, int* n_input_frames, int* n_target_frames)

virtual void preProcess(PreProcessing* pre_processing)

Inherited from Object:

Public Fields

Allocator* allocator

Public Methods

void addOption(const char* name, int size, void* ptr, const char* help="")

void addIOption(const char* name, int* ptr, int init_value, const char* help="")

void addROption(const char* name, real* ptr, real init_value, const char* help="")

void addBOption(const char* name, bool* ptr, bool init_value, const char* help="")

void addOOption(const char* name, Object** ptr, Object* init_value, const char* help="")

void setOption(const char* name, void* ptr)

void setIOption(const char* name, int option)

void setROption(const char* name, real option)

void setBOption(const char* name, bool option)

void setOOption(const char* name, Object* option)

virtual void loadXFile(XFile* file)

virtual void saveXFile(XFile* file)

void load(const char* filename)

void save(const char* filename)

void* operator new(size_t size, Allocator* allocator_=NULL)

void* operator new(size_t size, Allocator* allocator_, void* ptr_)

void operator delete(void* ptr)

Documentation

Given a DataSet, convert (on-the-fly) targets using a conversion table.

The targets of the given DataSet should be 0,1,2... for the class 0, class 1, class 2, and so on. Note that is must START AT 0.

After a setExample(), the inputs of this DataSet will be the same as the provided one. The targets will be class_labels->frames[i], where i is contained in the targets of the provided DataSet.

DataSet* data

The provided DataSet

Sequence* class_labels

The class label translation table

ClassFormatDataSet(DataSet* data_, Sequence* class_labels_)

Here you provide the translation table in class_labels_

ClassFormatDataSet(DataSet* data_, int n_classes=-1)

We assume here that you want the one-hot encoding format. The number of classes is given by n_classes, if positive. Otherwise, the number of classes is guessed by taking the maximum value of the targets of the provided DataSet.

This class has no child classes.
