Subtract 类tf_keras.layers.Subtract(**kwargs)
减去两个输入的层。
它接受一个包含两个相同形状张量的列表作为输入，并返回一个形状相同的单个张量，即 (inputs[0] - inputs[1])。
示例
import tf_keras.src as 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 subtracted = keras.layers.subtract([x1, x2])
subtracted = keras.layers.Subtract()([x1, x2])
out = keras.layers.Dense(4)(subtracted)
model = keras.models.Model(inputs=[input1, input2], outputs=out)
