nnet-simple-component.h File Reference

This file contains declarations of components that are "simple", meaning they don't care about the indexes they are operating on, produce one output for one input, and return the kSimpleComponent flag in their Properties(): for example, tanh and affine components. More...

class	AffineComponent
class	BlockAffineComponent
	This class implements an affine transform using a block diagonal matrix e.g., one whose weight matrix is all zeros except for blocks on the diagonal. More...

class	LinearComponent
class	FixedAffineComponent
	FixedAffineComponent is an affine transform that is supplied at network initialization time and is not trainable. More...
class	SumGroupComponent
	SumGroupComponent is used to sum up groups of posteriors. More...
class	FixedScaleComponent
	FixedScaleComponent applies a fixed per-element scale; it's similar to the Rescale component in the nnet1 setup (and only needed for nnet1 model conversion). More...
class	FixedBiasComponent
	FixedBiasComponent applies a fixed per-element bias; it's similar to the AddShift component in the nnet1 setup (and only needed for nnet1 model conversion. More...
class	NoOpComponent
	NoOpComponent just duplicates its input. More...
class	SumBlockComponent
	SumBlockComponent sums over blocks of its input: for instance, if you create one with the config "input-dim=400 output-dim=100", its output will be the sum over the 4 100-dimensional blocks of the input. More...

class	PermuteComponent
	PermuteComponent changes the order of the columns (i.e. More...
class	PerElementScaleComponent
	PerElementScaleComponent scales each dimension of its input with a separate trainable scale; it's like a linear component with a diagonal matrix. More...
class	PerElementOffsetComponent
class	ConstantFunctionComponent
class	NaturalGradientPerElementScaleComponent
	NaturalGradientPerElementScaleComponent is like PerElementScaleComponent but it uses a natural gradient update for the per-element scales. More...

Detailed Description

This file contains declarations of components that are "simple", meaning they don't care about the indexes they are operating on, produce one output for one input, and return the kSimpleComponent flag in their Properties(): for example, tanh and affine components.

In nnet-general-component.h there are components that don't fit this pattern.

Some components that do provide the kSimpleComponent flag are not declared here: see also nnet-normalize-component.h and nnet-combined-component.h
