Synapse.NN.Batching

Implements batching - technology that allows packing and processing multiple samples at once.

Sample datatype

data Sample a

Sample datatype represents known pair of inputs and outputs of function that is unknown.

Constructors

Sample

Fields

• sampleInput :: a

  Sample input.

• sampleOutput :: a

  Sample output.

Instances

Show a => Show (Sample a)

Defined in Synapse.NN.Batching

Methods

showsPrec :: Int -> Sample a -> ShowS

show :: Sample a -> String

showList :: [Sample a] -> ShowS

Eq a => Eq (Sample a)

Defined in Synapse.NN.Batching

Methods

(==) :: Sample a -> Sample a -> Bool

(/=) :: Sample a -> Sample a -> Bool

type DType (Sample a)

Defined in Synapse.NN.Batching

type DType (Sample a) = DType a

Dataset datatype

newtype Dataset a

Dataset newtype wraps vector of Samples - it represents known information about unknown function.

Constructors

Dataset

Fields

• unDataset :: Vec (Sample a)

  Unwraps Dataset newtype.

Instances

Show a => Show (Dataset a)

Defined in Synapse.NN.Batching

Methods

showsPrec :: Int -> Dataset a -> ShowS

show :: Dataset a -> String

showList :: [Dataset a] -> ShowS

Eq a => Eq (Dataset a)

Defined in Synapse.NN.Batching

Methods

(==) :: Dataset a -> Dataset a -> Bool

(/=) :: Dataset a -> Dataset a -> Bool

type DType (Dataset a)

Defined in Synapse.NN.Batching

type DType (Dataset a) = DType a

datasetSize :: Dataset a -> Int

Returns size of dataset.

shuffleDataset :: RandomGen g => Dataset a -> g -> (Dataset a, g)

Shuffles any Dataset using Fisher-Yates algorithm.

splitDataset :: Dataset a -> Float -> (Dataset a, Dataset a)

Splits dataset such that size of left dataset divided on size of right dataset will be equal to given ratio.

type VecDataset a = Dataset (Vec a)

VecDataset type alias represents Datasets with samples of vector functions.

type BatchedDataset a = Dataset (Mat a)

BatchedDataset type alias represents Datasets with samples of vector functions where multiple samples were batched together.

batchVectors :: Int -> VecDataset a -> BatchedDataset a

Batches VecDataset by grouping a given amount of samples into batches.
