Detailed Description

Dataset over a CSV file's numeric columns: N named feature columns -> one (1, num_features) Tensor per row, plus one named label column -> one (1,) Tensor. Requires a header row (feature/label columns are resolved by name).

Constructor & Destructor Documentation

◆ CsvDataset()

pulsatrix::CsvDataset::CsvDataset	(	const std::string &	path,
		std::vector< std::string >	feature_columns,
		std::string	label_column,
		DeviceBackend *	backend
	)

Parameters

path	CSV file path.
feature_columns	Column names to use as features, in order.
label_column	Column name to use as the label.
backend	Backend to allocate row Tensors through. Not owned.

Exceptions

std::runtime_error if the file can't be loaded (see CsvReader::Load), or a named feature/label column doesn't exist in the header – external boundary: column names are caller-supplied configuration, not internally derived.

Member Function Documentation

◆ get()

Sample pulsatrix::CsvDataset::get ( int64_t index ) const

overridevirtual

Exceptions

std::out_of_range	if index is out of bounds.
std::runtime_error	if a feature or label cell fails to parse as a float – external boundary: cell content originates from the file, not internal state.

Implements pulsatrix::Dataset.
