介绍
线性回归激活函数
Layer activation 指定
字符串"linear"
例子:
# 其他参数未指定
Conv2D( activation='linear')
语法
tf.keras.activations.linear(
x
)

def linear(x):
"""Linear activation function.
For example:
>>> a = tf.constant([-3.0,-1.0, 0.0,1.0,3.0], dtype = tf.float32)
>>> b = tf.keras.activations.linear(a)
>>> b.numpy()
array([-3., -1., 0., 1., 3.], dtype=float32)
Arguments:
x: Input tensor.
Returns:
the input unmodified.
