Python | Tensorflow asinh () method

Michael Zippo 18.07.2021

The tensorflow.math module provides support for many basic mathematical operations. The tf.asinh () [alias tf.math.asinh ] function provides support for the inverse hyperbolic sine function in Tensorflow. Input type — tensor, and if the input contains more than one element, the elementwise inverse hyperbolic sine is calculated.

Syntax : tf.asinh (x, name = None) or tf.math. asinh (x, name = None)

Parameters :
x : A tensor of any of the following types: float16, float32, float64, complex64, or complex128.
name (optional): The name for the operation.

Return type : A tensor with the same type as that of x.

Code # 1:

# Library import Tensorflow

import tensorflow as tf

# Constant vector of size 6

a = tf.constant ([ 1.0 , - 0.5 , 3.4 , 22.1 , 0.0 , - 6.5 ],

dtype = tf.float32)

# Using the asinh function and
# save the result to & # 39; b & # 39;

b = tf.asinh (a, name = ’asinh’ )

# Initiating a Tensorflow session
with tf.Session () as sess:

print ( ’Input type:’ , a)

print ( ’Input:’ , sess.run (a))

print ( ’Return type:’ , b)

print ( ’Output : ’ , sess.run (b))

Output :

 Input type: Tensor ("Const_1: 0", shape = (6,), dtype = float32) Input: [1. -0.5 3.4 22.1 0. -6.5] Return type: Tensor ("asinh: 0", shape = (6,) , dtype = float32) Output: [0.8813736 -0.48121184 1.9378793 3.7892363 0. -2.5708146]

Code # 2: Rendering

# Tensorflow library import

import tensorflow as tf

# Import NumPy library

import numpy as np

# Import matplotlib.pylot function

import matplotlib.pyplot as plt

# Vector size 15 with values from -10 to 10

a = np.linspace ( - 10 , 10 , 15 )

# Apply inverse hyperbolic sine
# function and save the result to & # 39; b & # 39;

b = tf.asinh (a, name = ’ asinh ’ )

# Initiating a Tensorflow session
with tf.Session () as sess:

print ( ’Input:’ , a)

     print   (  ’Output:’  , sess.run (b)) 
   plt.plot (a, sess.run (b), color   =   ’red’  , marker   =   "o"  ) 
   plt. title (  "tensorflow.asinh"  ) 
   plt.xlabel ( " X " )  
   plt.ylabel (  "Y"  ) 
   
   plt.show ()
