read_sampsetT_read_sampsetReadSampsetReadSampset (Operator)

Name

read_sampsetT_read_sampsetReadSampsetReadSampset — Read a training data set from a file.

Warning

read_sampsetread_sampsetReadSampsetReadSampsetReadSampset is obsolete and is only provided for reasons of backward compatibility. New applications should use the MLP, SVM, KNN or GMM operators instead.

Signature

read_sampset( : : FileName : SampKey)

Herror T_read_sampset(const Htuple FileName, Htuple* SampKey)

void ReadSampset(const HTuple& FileName, HTuple* SampKey)

void HFeatureSet::HFeatureSet(const HString& FileName)

void HFeatureSet::HFeatureSet(const char* FileName)

void HFeatureSet::ReadSampset(const HString& FileName)

void HFeatureSet::ReadSampset(const char* FileName)

static void HOperatorSet.ReadSampset(HTuple fileName, out HTuple sampKey)

public HFeatureSet(string fileName)

void HFeatureSet.ReadSampset(string fileName)

Description

The training examples are accessible with the key SampKeySampKeySampKeySampKeysampKey by calling the operators clear_sampsetclear_sampsetClearSampsetClearSampsetClearSampset and learn_sampset_boxlearn_sampset_boxLearnSampsetBoxLearnSampsetBoxLearnSampsetBox. You may edit the file using an editor. Every row contains an array of attributes with corresponding class. An example for a format might be: 

                       (1.0, 25.3, * , 17 | 3)
This row specifies an array of attributes which belong to class 3. In this array the third attribute is unknown. Attributes upwards 5 are supposed to be unknown, too. You may insert comments like /* .. */ in any place.

Execution Information

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Parameters

FileNameFileNameFileNameFileNamefileName (input_control)  filename.read → HTupleHTupleHtuple (string) (string) (HString) (char*)

Filename of the data set to train.

Default value: 'sampset1' "sampset1" "sampset1" "sampset1" "sampset1"

SampKeySampKeySampKeySampKeysampKey (output_control)  feature_set → HFeatureSet, HTupleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Identification of the data set to train.

Result

read_sampsetread_sampsetReadSampsetReadSampsetReadSampset returns 2 (H_MSG_TRUE). An exception is raised if it is not possible to open the file or it contains syntax errors or there is not enough memory.
