Tensorflow.js is an open-source library which is being developed by Google for running machine learning models as well as deep learning neural networks in the browser or node environment.
The .neg() function is used to calculate -1 * x i.e. input tensor and is done element wise.
Syntax:
tf.neg(x)
Parameters:
- x: It is the tensor input, and it can be of type tf.Tensor, or TypedArray, or Array.
Return Value: It returns the tf.Tensor object.
Example 1:
Javascript
// Importing the tensorflow.js library import * as tf from "@tensorflow/tfjs" // Defining tensor input elements const y = tf.tensor2d([6, 0, -9, -1], [4, 1]); // Calling neg() method and // printing output y.neg().print(); |
Output:
Tensor
[[-6],
[0 ],
[9 ],
[1 ]]
Example 2: In this example, the parameter is passed directly to the neg function.
Javascript
// Importing the tensorflow.js library import * as tf from "@tensorflow/tfjs" // Defining tensor input elements const y = tf.tensor2d([ 1.4, 0.98, -9.9, -1.5, 2.0, 6.5], [2, 3]); // Calling neg() method and var res = tf.neg(y); // printing output res.print(); |
Output:
Tensor
[[-1.4, -0.98, 9.8999996],
[1.5 , -2 , -6.5 ]]
