Detailed Description
template<typename T, class Tstate = bbstate_idx<T>>
class ebl::linear_module< T, Tstate >
This module applies a linears combination of the input <in> with its internal weight matrix w and puts the result in the output. This module has a replicable order of 1, if the input has a bigger order, use the replicable version of this module: linear_module_replicable.

| ebl::linear_module< T, Tstate >::linear_module | ( | parameter< T, Tstate > * | p, |
| intg | in, | ||
| intg | out, | ||
| const char * | name = "linear" |

| ) |
Constructor.
- Parameters:
-
p is used to store all parametric variables in a single place. If p is null, a local buffer will be used. in the size of the input to the linear combination. out the size of the output to the linear combination.
Member Function Documentation
| fidxdim ebl::linear_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 >.
| linear_module< T, Tstate > * ebl::linear_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::linear_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::linear_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.
Update output size based on weight dimensions
