Concatenate layer
Concatenate class
keras.layers.Concatenate(axis=-1, **kwargs)
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.
Examples
>>> x = np.arange(20).reshape(2, 2, 5)
>>> y = np.arange(20, 30).reshape(2, 1, 5)
>>> keras.layers.Concatenate(axis=1)([x, y])
Usage in a Keras model:
>>> x1 = keras.layers.Dense(8)(np.arange(10).reshape(5, 2))
>>> x2 = keras.layers.Dense(8)(np.arange(10, 20).reshape(5, 2))
>>> y = keras.layers.Concatenate()([x1, x2])
Arguments
- axis: Axis along which to concatenate.
- **kwargs: Standard layer keyword arguments.
Returns
A tensor, the concatenation of the inputs alongside axis axis.
