Description

Dataset abstraction.

Synopsis

data DataSet elem = DataSet {
- size :: Int
- elemAt :: Int -> IO elem
}
loadData :: DataSet a -> IO [a]
randomSample :: Int -> DataSet a -> IO [a]
withVect :: [a] -> (DataSet a -> IO b) -> IO b
withDisk :: Binary a => [a] -> (DataSet a -> IO b) -> IO b

Dataset

data DataSet elem Source #

Dataset stored on a disk

Constructors

DataSet
Fields size :: Int The size of the dataset; the individual indices are [0, 1, ..., size - 1] elemAt :: Int -> IO elem Get the dataset element with the given identifier

Reading

loadData :: DataSet a -> IO [a] Source #

Lazily load the entire dataset from a disk.

randomSample :: Int -> DataSet a -> IO [a] Source #

Random dataset sample with a specified number of elements (loaded eagerly)

Construction

withVect :: [a] -> (DataSet a -> IO b) -> IO b Source #

Construct dataset from a list of elements, store it as a vector, and run the given handler.

withDisk :: Binary a => [a] -> (DataSet a -> IO b) -> IO b Source #

Construct dataset from a list of elements, store it on a disk and run the given handler. Training elements must have the Binary instance for this function to work.
