描述
get_sample_class_train_dataget_sample_class_train_dataGetSampleClassTrainDataGetSampleClassTrainDataGetSampleClassTrainDataget_sample_class_train_data reads a training sample from the
training data given by ClassTrainDataHandleClassTrainDataHandleClassTrainDataHandleClassTrainDataHandleclassTrainDataHandleclass_train_data_handle that was
added, e.g., with add_sample_class_train_dataadd_sample_class_train_dataAddSampleClassTrainDataAddSampleClassTrainDataAddSampleClassTrainDataadd_sample_class_train_data。The index of the sample is
specified with IndexSampleIndexSampleIndexSampleIndexSampleindexSampleindex_sample. The index is counted from 0.
That means that IndexSampleIndexSampleIndexSampleIndexSampleindexSampleindex_sample must be a number between 0 and
NumSamplesNumSamplesNumSamplesNumSamplesnumSamplesnum_samples - 1, where NumSamplesNumSamplesNumSamplesNumSamplesnumSamplesnum_samples can be
determined with get_sample_num_class_train_dataget_sample_num_class_train_dataGetSampleNumClassTrainDataGetSampleNumClassTrainDataGetSampleNumClassTrainDataget_sample_num_class_train_data。The training
sample is returned in FeaturesFeaturesFeaturesFeaturesfeaturesfeatures and ClassIDClassIDClassIDClassIDclassIDclass_id.
FeaturesFeaturesFeaturesFeaturesfeaturesfeatures is a feature vector of length NumDimNumDimNumDimNumDimnumDimnum_dim
(see create_class_train_datacreate_class_train_dataCreateClassTrainDataCreateClassTrainDataCreateClassTrainDatacreate_class_train_data) and ClassIDClassIDClassIDClassIDclassIDclass_id is
the class of the feature vector.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
