clear_samples_class_svm🔗
Short description🔗
clear_samples_class_svm — Clear the training data of a support vector machine.
Signature🔗
clear_samples_class_svm( class_svm SVMHandle )
Description🔗
clear_samples_class_svm clears all training samples that
have been added to the support vector machine (SVM)
SVMHandle with add_sample_class_svm or
read_samples_class_svm. clear_samples_class_svm
should only be used if the SVM is trained in the same process that
uses the SVM for classification with classify_class_svm. In
this case, the memory required for the training samples can be freed
with clear_samples_class_svm, 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_svm, it is typically unnecessary
to call clear_samples_class_svm because
write_class_svm does not save the training samples, and
hence the online process, which reads the SVM with
read_class_svm, requires no memory for the training
samples.
Execution information🔗
Execution information
-
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:
During execution of this operator, access to the value of this parameter must be synchronized if it is used across multiple threads.
Parameters🔗
SVMHandle (input_control, state is modified) class_svm(-array) → (handle)
SVM handle.
Result🔗
If the parameters are valid the operator
clear_samples_class_svm returns the value 2 (H_MSG_TRUE). If
necessary, an exception is raised.
