Constructor & Destructor Documentation

DataLoader()

template<typename T >

dl::utils::DataLoader< T >::DataLoader	(	const Dataset< T > &	dataset,
		size_t	batch_size,
		bool	shuffle = false
	)

Constructor for data loader.

Parameters

dataset	Reference to the dataset to iterate over
batch_size	Number of samples per batch
shuffle	Whether to shuffle data at the start of each epoch

Definition at line 59 of file data_loader.cpp.

Member Function Documentation

has_next()

template<typename T >

bool dl::utils::DataLoader< T >::has_next

(

)

const

Check if more batches are available in current epoch.

Returns

True if more batches exist, false otherwise

Examples

/home/runner/work/deep-learning-algo-impls/deep-learning-algo-impls/include/utils/data_loader.hpp.

Definition at line 65 of file data_loader.cpp.

next_batch()

template<typename T >

std::pair< MatrixD, MatrixD > dl::utils::DataLoader< T >::next_batch

(

)

Get the next batch of data.

Returns

Pair of (features, labels) matrices for the next batch

Note

Advances the internal iterator. Call has_next() first to check availability

Examples

/home/runner/work/deep-learning-algo-impls/deep-learning-algo-impls/include/utils/data_loader.hpp.

Definition at line 71 of file data_loader.cpp.

reset()

template<typename T >

void dl::utils::DataLoader< T >::reset

(

)

Reset iterator to start of dataset.

Note

If shuffle is enabled, reshuffles the dataset

Examples

/home/runner/work/deep-learning-algo-impls/deep-learning-algo-impls/include/utils/data_loader.hpp.
