**Multiplex Layer**
|
|
|
|
|
|
|
|
|
|
Referring to the given index variable, this layer gathers from the input
|
|
|
|
|
variables to output a multiplex variable. Assuming that there are :math:`m`
|
|
|
|
|
input variables and let :math:`I_i` represents the i-th input variable and i
|
|
|
|
|
is in [0, :math:`m`). All input variables are tensors with same shape
|
|
|
|
|
[:math:`d_0`, :math:`d_1`, ..., :math:`d_R`]. Please note that rank of the
|
|
|
|
|
input tensor should be at least 2. Each input variable will be treated as a
|
|
|
|
|
2-D matrix with shape [:math:`M`, :math:`N`] where :math:`M` for :math:`d_0`
|
|
|
|
|
and :math:`N` for :math:`d_1` * :math:`d_2` * ... * :math:`d_R`. Let
|
|
|
|
|
:math:`I_i[j]` be the j-th row of the i-th input variable. The given index
|
|
|
|
|
variable should be a 2-D tensor with shape [:math:`M`, 1]. Let `ID[i]` be
|
|
|
|
|
the i-th index value of the index variable. Then the output variable will
|
|
|
|
|
be a tensor with shape [:math:`d_0`, :math:`d_1`, ..., :math:`d_R`]. If we
|
|
|
|
|
treat the output tensor as a 2-D matrix with shape [:math:`M`, :math:`N`]
|
|
|
|
|
and let :math:`O[i]` be the i-th row of the matrix, then `O[i]` is equal to
|
|
|
|
|
:math:`I_{ID[i]}[i]`.
|
|
|
|
|
Referring to the given index variable, this layer selects rows from the
|
|
|
|
|
input variables to construct a multiplex variable. Assuming that there are
|
|
|
|
|
:math:`m` input variables and :math:`I_i` represents the i-th input
|
|
|
|
|
variable and :math:`i` is in [0, :math:`m`). All input variables are
|
|
|
|
|
tensors with same shape [:math:`d_0`, :math:`d_1`, ..., :math:`d_R`].

|

Please note that rank of the input tensor should be at least 2. Each input
|
|
|
|

variable will be treated as a 2-D matrix with shape [:math:`M`, :math:`N`]
|

where :math:`M` for :math:`d_0` and :math:`N` for :math:`d_1` * :math:`d_2`
|
|
|
|
|
* ... * :math:`d_R`. Let :math:`I_i[j]` be the j-th row of the i-th input
|
|
|
|
|
variable. The given index variable should be a 2-D tensor with shape
|
|
|
|
|
[:math:`M`, 1]. Let `ID[i]` be the i-th index value of the index variable.
|
|

Then the output variable will be a tensor with shape [:math:`d_0`,

matrix with shape [:math:`M`, :math:`N`] and let :math:`O[i]` be the i-th
