Concatenates a list of inputs.

It takes as input a list of tensors, all of the same shape except for the concatenation axis, and returns a single tensor that is the concatenation of all inputs.

Usage

layer_concatenate(inputs, ..., axis = -1L)

Arguments

inputs: layers to combine
...: Standard layer keyword arguments.
axis: Axis along which to concatenate.

Value

A tensor, the concatenation of the inputs alongside axis axis.

Examples

x <- op_arange(20) |> op_reshape(c(2, 2, 5))
y <- op_arange(21, 40) |> op_reshape(c(2, 2, 5))
layer_concatenate(x, y, axis = 2)

## tf.Tensor(
## [[[ 1.  2.  3.  4.  5.]
##   [ 6.  7.  8.  9. 10.]
##   [21. 22. 23. 24. 25.]
##   [26. 27. 28. 29. 30.]]
##
##  [[11. 12. 13. 14. 15.]
##   [16. 17. 18. 19. 20.]
##   [31. 32. 33. 34. 35.]
##   [36. 37. 38. 39. 40.]]], shape=(2, 4, 5), dtype=float32)

Usage in a Keras model:

x1 <- op_arange(10)     |> op_reshape(c(5, 2)) |> layer_dense(8)
x2 <- op_arange(11, 20) |> op_reshape(c(5, 2)) |> layer_dense(8)
y <- layer_concatenate(x1, x2)
