genericROM.OperatorCompressors.Regression module

CompressOperator(collectionProblemData, regressors)[source]

Computes the offline operator compression stage using the method of POD on the snapshots and a regression on the coefficients

Parameters:

  • collectionProblemData (CollectionProblemData) – definition of the training data in a CollectionProblemData object

  • regressors (list of regressor OperationCompressionData instances) – regressors defined in Containers/OperationCompressionData/Regressors

ComputeOnline(onlineProblemData, solutionName)[source]

Compute the online stage using the method of POD on the snapshots and a regression on the coefficients

The parameters must have been initialized in onlineProblemData

Parameters:

  • onlineProblemData (ProblemData) – definition of the testing configuration data in a CollectionProblemData object

  • solutionName (str) – names of the solution to be treated

Returns:

onlineReducedCoordinates; dictionary with time indices as keys and a np.ndarray of size (numberOfModes,) containing the coefficients of the reduced solution

Return type:

dict
