Tensorflow is an open-source machine learning library developed by Google. One of its applications is to develop deep neural networks.
The module tensorflow.math
provides support for many basic mathematical operations. Function tf.asinh()
[alias tf.math.asinh
] provides support for the inverse hyperbolic sine function in Tensorflow. The input type is tensor and if the input contains more than one element, element-wise inverse hyperbolic sine is computed.
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:
Python3
# Importing the Tensorflow library import tensorflow as tf # A constant vector of size 6 a = tf.constant([ 1.0 , - 0.5 , 3.4 , 22.1 , 0.0 , - 6.5 ], dtype = tf.float32) # Applying the asinh function and # storing the result in 'b' 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 ]
