Name

read_sampsetread_sampsetread_sampsetReadSampsetReadSampset — Read a training data set from a file.

Signature

read_sampset( : : FileName : SampKey)

Herror read_sampset(const char* FileName, Hlong* SampKey)

Herror T_read_sampset(const Htuple FileName, Htuple* SampKey)

Herror read_sampset(const HTuple& FileName, Hlong* SampKey)

void HOperatorSetX.ReadSampset(
[in] VARIANT FileName, [out] VARIANT* SampKey)

void HFeatureSetX.ReadSampset([in] BSTR 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 operators clear_sampsetclear_sampsetclear_sampsetClearSampsetClearSampset and learn_sampset_boxlearn_sampset_boxlearn_sampset_boxLearnSampsetBoxLearnSampsetBox. 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.

Result

read_sampsetread_sampsetread_sampsetReadSampsetReadSampset 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.
