Python – tensorflow.math.erfinv()
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。
erfinv()用于计算元素间的反误差函数。
语法: tensorflow.math.erfinv( x, name)
参数:
- x:是输入的张量。允许的d类型是bfloat16, half, float32, float64。
- name(可选):它定义了该操作的名称。
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([.1, .2, .3, .4, .5], dtype = tf.float64)
# Printing the input tensor
print('Input: ', a)
# Calculating inverse error
res = tf.math.erfinv(x = a)
# Printing the result
print('Result: ', res)
输出:
Input: tf.Tensor([0.1 0.2 0.3 0.4 0.5], shape=(5, ), dtype=float64)
Result: tf.Tensor([0.08885599 0.17914345 0.27246271 0.37080716 0.47693628], 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([.1, .2, .3, .4, .5], dtype = tf.float64)
# Calculating inverse error
res = tf.math.erfinv(x = a)
# Plotting the graph
plt.plot(a, res, color ='green')
plt.title('tensorflow.math.erfinv')
plt.xlabel('Input')
plt.ylabel('Result')
plt.show()
输出:
