Detailed Description

This module takes the l2 norm of neighborhoods with a stride, e.g. a 5x5 l2 pooling with a stride of 2x2.

Constructor & Destructor Documentation

template<typename T , class Tstate >

ebl::lppooling_module< T, Tstate >::lppooling_module	(	uint	thickness,
		idxdim &	kernel,
		idxdim &	stride,
		uint	lppower = `2`,
		const char *	name = `"lppooling"`,
		bool	crop = `true`
	)

Constructor.

Parameters:

p	is used to store all parametric variables in a single place. If p is null, a local buffer will be used.
thickness	The number of features.
kernel	Size of subsampling kernel (without thickness).
stride	Stride of subsampling kernel (without thickness).
crop	If true, crop input when it does not match with the kernel. This allows to feed any input size to this module.

template<typename T , class Tstate >

fidxdim ebl::lppooling_module< T, Tstate >::bprop_size ( const fidxdim & o_size ) [virtual]

Return dimensions compatible with this module given output dimensions. See module_1_1_gen's documentation for more details.

template<typename T , class Tstate >

void ebl::lppooling_module< T, Tstate >::dump_fprop	(	Tstate &	in,
		Tstate &	out
	)		`[virtual]`

Calls fprop and then dumps internal buffers, inputs and outputs into files. This can be useful for debugging.

template<typename T , class Tstate >

fidxdim ebl::lppooling_module< T, Tstate >::fprop_size ( fidxdim & i_size ) [virtual]

Return dimensions that are compatible with this module. See module_1_1_gen's documentation for more details.

template<typename T, class Tstate = bbstate_idx<T>>

uint ebl::lppooling_module< T, Tstate >::lp_pow [protected]

Crop input when size mismatch or not.
