Concatenate layer

[source]

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.
