TMVA::DNN::TDataLoader< Data_t, AArchitecture > Class Template Reference

template<typename Data_t, typename AArchitecture>
class TMVA::DNN::TDataLoader< Data_t, AArchitecture >

TDataLoader.

Service class managing the streaming of the training data from the input data type to the accelerator device or the CPU. A TDataLoader object manages a number of host and device buffer pairs that are used in a round-robin manner for the transfer of batches to the device.

Each TDataLoader object has an associated batch size and a number of total samples in the dataset. One epoch is the number of buffers required to transfer the complete training set. Using the begin() and end() member functions allows the user to iterate over the batches in one epoch.

Template Parameters
ADataThe input data type.
AArchitectureThe achitecture class of the underlying architecture.
