TensorFlow is open-source Python library designed by Google to develop Machine Learning models and deep learning neural networks.
erf() is used to compute element wise Gauss error function.
Syntax: tensorflow.math.erf( 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
# 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 Gauss error res = tf.math.erf(x = a)
# Printing the result print ( 'Result: ' , res)
|
Output:
Input: tf.Tensor([1. 2. 3. 4. 5.], shape=(5, ), dtype=float64) Result: tf.Tensor([0.84270079 0.99532227 0.99997791 0.99999998 1. ], shape=(5, ), dtype=float64)
Example 2: Visualization
Python3
# 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 Gauss error res = tf.math.erf(x = a)
# Plotting the graph plt.plot(a, res, color = 'green' )
plt.title( 'tensorflow.math.erf' )
plt.xlabel( 'Input' )
plt.ylabel( 'Result' )
plt.show() |
