Last Updated :
16 Jun, 2020
TensorFlow is open-source Python library designed by Google to develop Machine Learning models and deep learning neural networks.
softplus() is used to compute element wise log(exp(features) + 1).
Syntax: tensorflow.math.softplus(features, name)
Parameters:
- features: It’s a tensor. Allowed dtypes are half, bfloat16, float32, float64.
- name(optional): It defines the name for the operation.
Returns: It returns a tensor.
Example 1:
Python3
import tensorflow as tf
a = tf.constant([ 5 , 7 , 9 , 15 ], dtype = tf.float64)
print ( 'a: ' , a)
res = tf.math.softplus(a)
print ( 'Result: ' , res)
|
Output:
a: tf.Tensor([ 5. 7. 9. 15.], shape=(4, ), dtype=float64)
Result: tf.Tensor([ 5.00671535 7.00091147 9.0001234 15.00000031], shape=(4, ), dtype=float64)
Example 2: Visualization
Python3
import tensorflow as tf
import matplotlib.pyplot as plt
a = tf.constant([ 5 , 7 , 9 , 15 ], dtype = tf.float64)
res = tf.math.softplus(a)
plt.plot(a, res, color = 'green' )
plt.title( 'tensorflow.math.softplus' )
plt.xlabel( 'Input' )
plt.ylabel( 'Result' )
plt.show()
