Tensorflow tf.add() Function

Last Updated : 07 Jun, 2022

The tf.add() function returns the addition of two tf.Tensor objects element wise. The tf.Tensor object represents the multidimensional array of numbers.

Syntax:

tf.add( a, b )

Parameters:

a: It contains the first tf.Tensor object that is to be added. The value of this parameter can be tf.TensorTypedArray|Array.
b: It contains the second tf.Tensor object that is to be added into the first tf.Tensor object. The value of this parameter can be (tf.Tensor|TypedArray|Array). The type of this parameter is same as type of a.

Return Value: This function returns the tf.Tensor object.

Example 1:

JavaScript

// Importing the tensorflow.js library 
import * as tf from "@tensorflow/tfjs"

// Declare the Tensor array
const arr1 = tf.tensor1d([10, 20, 30, 40, 50]);
const arr2 = tf.tensor1d([5, 10, 15, 20, 25]);

// Use add() function to add
// two Tensor objects
arr1.add(arr2).print();

Output:

Tensor
    [15, 30, 45, 60, 75]

Example 2:

JavaScript

// Importing the tensorflow.js library 
import * as tf from "@tensorflow/tfjs"

// Declare the Tensor array
const arr1 = tf.tensor1d([30, 40, 50]);
const arr2 = tf.tensor1d([5, 10, 15, 20, 25]);

// Use add() function to add
// two Tensor objects
arr1.add(arr2).print();

Output:

Example 3:

JavaScript

// Importing the tensorflow.js library 
import * as tf from "@tensorflow/tfjs"

// Declare the Tensor array
const arr = tf.tensor1d([5, 10, 15, 20, 25]);

// Declare a number
const num = tf.scalar(30);

// Use add() function to add
// Tensor object and a number
arr.add(num).print();
