Tensorflow.js tf.reverse() Function

Tensorflow.js is an open-source library developed by Google for running machine learning models and deep learning neural networks in the browser or node environment. It also helps the developers to develop ML models in JavaScript language and can use ML directly in the browser or in Node.js.

The tf.reverse() function is used to reverse a tf.tensors along a specific axis.

Syntax:

tf.reverse(x, axis)

Parameters:

• x: An input tensor to be reversed.
• axis: The set of dimensions to be set.

Return Value: This function returns tf.Tensor.

Example 1:

Javascript

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

// Creating a tensor
const gfg = tf.tensor1d([4, 3, 2, 1]);

// Printing tensor
gfg.reverse().print();

Output:

Tensor
    [1, 2, 3, 4]

Example 2:

Javascript

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

// Creating a tensor
const x = tf.tensor2d([2, 1, 4, 3, 6, 5], [3, 2]);

// Initialize the axis
const axis = 1;

// Printing the tensor
x.reverse(axis).print();

Output:

Tensor
    [[1, 2],
     [3, 4],
     [5, 6]]
