clear_samples_class_svmclear_samples_class_svmClearSamplesClassSvmClearSamplesClassSvmClearSamplesClassSvm clears all training samples that
have been added to the support vector machine (SVM)
SVMHandleSVMHandleSVMHandleSVMHandleSVMHandle with add_sample_class_svmadd_sample_class_svmAddSampleClassSvmAddSampleClassSvmAddSampleClassSvm or
read_samples_class_svmread_samples_class_svmReadSamplesClassSvmReadSamplesClassSvmReadSamplesClassSvm. clear_samples_class_svmclear_samples_class_svmClearSamplesClassSvmClearSamplesClassSvmClearSamplesClassSvm
should only be used if the SVM is trained in the same process that
uses the SVM for classification with classify_class_svmclassify_class_svmClassifyClassSvmClassifyClassSvmClassifyClassSvm. In
this case, the memory required for the training samples can be freed
with clear_samples_class_svmclear_samples_class_svmClearSamplesClassSvmClearSamplesClassSvmClearSamplesClassSvm, and hence memory can be saved.
In the normal usage, in which the SVM is trained offline and written
to a file with write_class_svmwrite_class_svmWriteClassSvmWriteClassSvmWriteClassSvm, it is typically unnecessary
to call clear_samples_class_svmclear_samples_class_svmClearSamplesClassSvmClearSamplesClassSvmClearSamplesClassSvm because
write_class_svmwrite_class_svmWriteClassSvmWriteClassSvmWriteClassSvm does not save the training samples, and
hence the online process, which reads the SVM with
read_class_svmread_class_svmReadClassSvmReadClassSvmReadClassSvm, requires no memory for the training
samples.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
This operator modifies the state of the following input parameter:
The value of this parameter may not be shared across multiple threads without external synchronization.
If the parameters are valid the operator
clear_samples_class_svmclear_samples_class_svmClearSamplesClassSvmClearSamplesClassSvmClearSamplesClassSvm returns the value 2 (H_MSG_TRUE). If
necessary, an exception is raised.
