Name
clear_samples_class_gmmT_clear_samples_class_gmmClearSamplesClassGmmClearSamplesClassGmmclear_samples_class_gmm
— Clear the training data of a Gaussian Mixture Model.
Signature
Herror T_clear_samples_class_gmm(const Htuple GMMHandle)
def clear_samples_class_gmm(gmmhandle: MaybeSequence[HHandle]) -> None
Description
clear_samples_class_gmmclear_samples_class_gmmClearSamplesClassGmmClearSamplesClassGmmClearSamplesClassGmmclear_samples_class_gmm
clears all training samples that
have been stored in the Gaussian Mixture Model (GMM)
GMMHandleGMMHandleGMMHandleGMMHandleGMMHandlegmmhandle
. clear_samples_class_gmmclear_samples_class_gmmClearSamplesClassGmmClearSamplesClassGmmClearSamplesClassGmmclear_samples_class_gmm
should only be
used if the GMM is trained in the same process that uses the GMM for
evaluation with evaluate_class_gmmevaluate_class_gmmEvaluateClassGmmEvaluateClassGmmEvaluateClassGmmevaluate_class_gmm
or for classification
with classify_class_gmmclassify_class_gmmClassifyClassGmmClassifyClassGmmClassifyClassGmmclassify_class_gmm
. In this case, the memory required
for the training samples can be freed with
clear_samples_class_gmmclear_samples_class_gmmClearSamplesClassGmmClearSamplesClassGmmClearSamplesClassGmmclear_samples_class_gmm
, and hence memory can be saved. In
the normal usage, in which the GMM is trained offline and written to
a file with write_class_gmmwrite_class_gmmWriteClassGmmWriteClassGmmWriteClassGmmwrite_class_gmm
, it is typically unnecessary to
call clear_samples_class_gmmclear_samples_class_gmmClearSamplesClassGmmClearSamplesClassGmmClearSamplesClassGmmclear_samples_class_gmm
because write_class_gmmwrite_class_gmmWriteClassGmmWriteClassGmmWriteClassGmmwrite_class_gmm
does not save the training samples, and hence the online process,
which reads the GMM with read_class_gmmread_class_gmmReadClassGmmReadClassGmmReadClassGmmread_class_gmm
, requires no memory
for the training samples.
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

Result
If the parameters are valid, the operator
clear_samples_class_gmmclear_samples_class_gmmClearSamplesClassGmmClearSamplesClassGmmClearSamplesClassGmmclear_samples_class_gmm
returns the value 2 (H_MSG_TRUE). If
necessary an exception is raised.
