Detailed Description
template<typename T, class Tstate = bbstate_idx<T>>
class ebl::subsampling_module< T, Tstate >
This module applies 2D subsampling on dimensions 1 and 2 (0 contains different layers of information). This module has a replicable order of 3, if the input has a bigger order, use the replicable version of this module: subsampling_module_replicable.

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. pad If true, add padding to end of non-feature dimensions to match the kernel when not matching.
Member Function Documentation
| fidxdim ebl::subsampling_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.
Just multiply each dimension by its stride
Reimplemented from ebl::module_1_1< T, Tstate >.
| void ebl::subsampling_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.
Reimplemented from ebl::module_1_1< T, Tstate >.
| fidxdim ebl::subsampling_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.
Recompute the input size to be compliant with the output
Reimplemented from ebl::module_1_1< T, Tstate >.
