tensorflow.math.l2\_normalize()TensorFlow是谷歌设计的开源Python库,用于开发机器学习模型和深度学习神经网络。
tensorflow.math.l2\_normalize()用于使用L2准则将张量沿轴线归一。
语法:
tensorflow.math.l2_normalize( x, axis, epsilon, name)
参数:
返回值:
它返回一个与x相同形状的张量。
示例 1:
# Importing the library
import tensorflow as tf
# Initializing the input tensor
a = tf.constant([7, 8, 13, 11], dtype = tf.float64)
# Printing the input tensor
print('a: ', a)
# Calculating the result
res = tf.math.l2_normalize(a)
# Printing the result
print('Result: ', res)
输出:
a: tf.Tensor([ 7. 8. 13. 11.], shape=(4, ), dtype=float64)
Result: tf.Tensor([0.34869484 0.39850839 0.64757613 0.54794903], shape=(4, ), dtype=float64)
例子2:这个例子使用2-D张量。
# Importing the library
import tensorflow as tf
# Initializing the input tensor
a = tf.constant([[7, 8], [13, 11]], dtype = tf.float64)
# Printing the input tensor
print('a: ', a)
# Calculating the result
res = tf.math.l2_normalize(x = a, axis = 1)
# Printing the result
print('Result: ', res)
输出:
a: tf.Tensor(
[[ 7. 8.]
[13. 11.]], shape=(2, 2), dtype=float64)
Result: tf.Tensor(
[[0.65850461 0.75257669]
[0.76338629 0.64594224]], shape=(2, 2), dtype=float64)
