Constructor & Destructor Documentation

◆ RBatchLoader()

TMVA::Experimental::Internal::RBatchLoader::RBatchLoader ( std::size_t batchSize,
std::size_t numColumns )
inline

Definition at line 70 of file RBatchLoader.hxx.

Member Function Documentation

◆ Activate()

void TMVA::Experimental::Internal::RBatchLoader::Activate ( )
inline

Definition at line 84 of file RBatchLoader.hxx.

◆ CreateBatch()

std::unique_ptr< RFlat2DMatrix > TMVA::Experimental::Internal::RBatchLoader::CreateBatch ( RFlat2DMatrix & chunTensor,
std::size_t idxs )
inline

Return a batch of data as a unique pointer.

After the batch has been processed, it should be destroyed.

Parameters
[in]chunkTensorRTensor with the data from the chunk
[in]idxsIndex of batch in the chunk
Returns
Training batch

Definition at line 109 of file RBatchLoader.hxx.

◆ CreateTrainingBatches()

void TMVA::Experimental::Internal::RBatchLoader::CreateTrainingBatches ( RFlat2DMatrix & chunkTensor,
int lastbatch,
std::size_t leftoverBatchSize,
bool dropRemainder )
inline

Creating the training batches from a chunk and add them to the queue.

Parameters
[in]chunkTensorRTensor with the data from the chunk
[in]lastbatchCheck if the batch in the chunk is the last one
[in]leftoverBatchSizeSize of the leftover batch in the training dataset
[in]dromRemainderBool to drop the remainder batch or not

Definition at line 156 of file RBatchLoader.hxx.

◆ CreateValidationBatches()

void TMVA::Experimental::Internal::RBatchLoader::CreateValidationBatches ( RFlat2DMatrix & chunkTensor,
std::size_t lastbatch,
std::size_t leftoverBatchSize,
bool dropRemainder )
inline

Creating the validation batches from a chunk and adding them to the queue.

Parameters
[in]chunkTensorRTensor with the data from the chunk
[in]lastbatchCheck if the batch in the chunk is the last one
[in]leftoverBatchSizeSize of the leftover batch in the validation dataset
[in]dropRemainderBool to drop the remainder batch or not

Definition at line 251 of file RBatchLoader.hxx.

◆ DeActivate()

void TMVA::Experimental::Internal::RBatchLoader::DeActivate ( )
inline

DeActivate the batchloader.

This means that no more batches are created. Batches can still be returned if they are already loaded

Definition at line 95 of file RBatchLoader.hxx.

inline

Definition at line 322 of file RBatchLoader.hxx.

◆ GetTrainBatch()

RFlat2DMatrix TMVA::Experimental::Internal::RBatchLoader::GetTrainBatch ( )
inline

Loading the training batch from the queue.

Returns
Training batch

Definition at line 120 of file RBatchLoader.hxx.

◆ GetValidationBatch()

RFlat2DMatrix TMVA::Experimental::Internal::RBatchLoader::GetValidationBatch ( )
inline

Loading the validation batch from the queue.

Returns
Validation batch

Definition at line 136 of file RBatchLoader.hxx.
