Class Add

Layer that adds a list of inputs.


  • Class tf.compat.v1.keras.layers.Add
  • Class tf.compat.v2.keras.layers.Add

It takes as input a list of tensors, all of the same shape, and returns a single tensor (also of the same shape).


    import keras

    input1 = keras.layers.Input(shape=(16,))
    x1 = keras.layers.Dense(8, activation='relu')(input1)
    input2 = keras.layers.Input(shape=(32,))
    x2 = keras.layers.Dense(8, activation='relu')(input2)
    # equivalent to `added = keras.layers.add([x1, x2])`
    added = keras.layers.Add()([x1, x2])
    out = keras.layers.Dense(4)(added)
    model = keras.models.Model(inputs=[input1, input2], outputs=out)
