Concat Forward Layer

The forward concat layer generates a tensor from input arguments
X
.

Problem Statement

Given the dimension
k
along which the concatenation to be implemented and
t
p
-dimensional tensors
X
(
i
)
,
i
=1, ...,
t
, of size
n
1
x
n
2
x ... x
n
k
i
... x
n
p
, where
n
1
, ...,
n
k
-1
,
n
k
+1
, ...,
n
p
are the same for all tensors, the problem is to generate
  • The
    p
    -dimensional tensor
    Y
    = (
    y
    i
    1
    ...
    i
    p
    ) of size
    n
    1
    x...x
    n
    k
    x ... x
    n
    p
    , such that:
  • A collection of sizes
    n
    k
    i
    along the
    k
    -th dimension.
