Last Updated :
08 Jun, 2020
TensorFlow is open-source Python library designed by Google to develop Machine Learning models and deep learning neural networks.
erfinv() is used to compute element wise inverse error function.
Syntax: tensorflow.math.erfinv( x, name)
Parameters:
- x: It’s the input tensor. Allowed dtypes are bfloat16, half, float32, float64.
- name(optional): It defines the name for the operation.
Returns: It returns a tensor of same dtype as x.
Example 1:
Python3
import tensorflow as tf
a = tf.constant([. 1 , . 2 , . 3 , . 4 , . 5 ], dtype = tf.float64)
print ( 'Input: ' , a)
res = tf.math.erfinv(x = a)
print ( 'Result: ' , res)
|
Output:
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)
Example 2: Visualization
Python3
import tensorflow as tf
import matplotlib.pyplot as plt
a = tf.constant([. 1 , . 2 , . 3 , . 4 , . 5 ], dtype = tf.float64)
res = tf.math.erfinv(x = a)
plt.plot(a, res, color = 'green' )
plt.title( 'tensorflow.math.erfinv' )
plt.xlabel( 'Input' )
plt.ylabel( 'Result' )
plt.show()
