Detailed Description
template<typename T, class Tstate = bbstate_idx<T>>
class ebl::convolution_module< T, Tstate >
This module applies 2D convolutions 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: convolution_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. ker The convolution kernel sizes. stride The convolution strides. table is the convolution connection table. crop If true, crop input when it does not match with the kernel. This allows to feed any input size to this module.
Member Function Documentation
| fidxdim ebl::convolution_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.
Reimplemented from ebl::module_1_1< T, Tstate >.
| convolution_module< T, Tstate > * ebl::convolution_module< T, Tstate >::copy | ( | parameter< T, Tstate > * | p = NULL | ) | [virtual] |
Returns a deep copy of this module.
- Parameters:
-
p If NULL, reuse current parameter space, otherwise allocate new weights on parameter 'p'.
Reimplemented from ebl::module_1_1< T, Tstate >.
| void ebl::convolution_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::convolution_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 >.
| bool ebl::convolution_module< T, Tstate >::resize_output | ( | Tstate & | in, |
| Tstate & | out | ||
| ) | [virtual] |
resize the output based on input dimensions This returns true if output was resized/reallocated, false otherwise.
Member Data Documentation
idx<T> ebl::convolution_module< T, Tstate >::revkernel [protected] |
Crop input when size mismatch or not.
