bias	A vector of pointers to bias vectors for each layer.
dimensions	A vector containing the dimensions of the neural network layers.

Member Function Documentation

apply()

void TorchDNN_Multi::apply ( const SelectivityVector & rows, std::vector< VectorPtr > & args, const TypePtr & type, exec::EvalCtx & context, VectorPtr & output ) const

inlineoverride

Applies the multi-layer neural network to the input array.

This method processes the input array, applies the neural network, and stores the result in the output vector.

Parameters

rows	A SelectivityVector specifying the rows to process.
args	A vector of input arguments (e.g., the input array).
type	The type of the output vector.
context	The execution context.
output	The output vector where the result will be stored.

getBias()

const std::vector< float * > & TorchDNN_Multi::getBias ( ) const

inline

Returns the biases of the neural network.

Returns

A vector of pointers to bias vectors.

getTensor()

float * TorchDNN_Multi::getTensor ( ) const

inlineoverridevirtual

Returns the tensor associated with this function.

Returns

A pointer to an empty float array (no weights for TorchDNN_Multi).

Implements MLFunction.

getWeights()

const std::vector< float * > & TorchDNN_Multi::getWeights ( ) const

inline

Returns the weights of the neural network.

Returns

A vector of pointers to weight matrices.

signatures()

static std::vector< std::shared_ptr< exec::FunctionSignature > > TorchDNN_Multi::signatures ( )

inlinestatic

Returns the function signatures supported by this class.

Returns

A vector of shared pointers to FunctionSignature objects.
