Python – tensorflow.math.cosh()
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。cosh()用于查找x的元素明智的双曲cos。
语法: tf.math.cosh(x, name)
参数:
- x:它是输入的张量。这个张量允许的dtype是bfloat16, half, float32, float64。
- name(可选):它定义了操作的名称。
返回:它返回一个与x具有相同dtype的张量。
示例 1:
# Importing the library
import tensorflow as tf
# Initializing the input tensor
a = tf.constant([ -.5, -.3, 0, .3, .5], dtype = tf.float64)
# Printing the input tensor
print('Input: ', a)
# Calculating tangent
res = tf.math.cosh(x = a)
# Printing the result
print('Result: ', res)
输出:
Input: tf.Tensor([-0.5 -0.3 0. 0.3 0.5], shape=(5, ), dtype=float64)
Result: tf.Tensor([1.12762597 1.04533851 1. 1.04533851 1.12762597], shape=(5, ), dtype=float64)
例子2:视觉化
# Importing the library
import tensorflow as tf
import matplotlib.pyplot as plt
# Initializing the input tensor
a = tf.constant([-.5, -.3, 0, .3, .5], dtype = tf.float64)
# Calculating tangent
res = tf.math.cosh(x = a)
# Plotting the graph
plt.plot(a, res, color ='green')
plt.title('tensorflow.math.cosh')
plt.xlabel('Input')
plt.ylabel('Result')
plt.show()
输出:
