Tensorflow.js is an open-source library that is developed by Google for running machine learning models as well as deep learning neural networks in the browser or node environment.
The .scatterND() function is used to form a different tensor by utilizing scattered updates to the individual slices or values inside a zero tensor of the stated shape tensor in accordance with the stated indices. Moreover, this function is negation of the tf.gatherND() function that takes slices or values from a stated tensor.
Syntax: Â
tf.scatterND(indices, updates, shape)
Parameters: Â
- indices: It is the stated tensor that holds the indices towards the output tensor, and it can be of type tf.Tensor, TypedArray, or Array.
- updates: It is the stated tensor that holds the values for the indices, and it can be of type tf.Tensor, TypedArray, or Array.
- shape: It is the stated shape of the output tensor and is of type number[].
Return Value: It returns tf.Tensor object.
Example 1:
Javascript
// Importing the tensorflow.js library import * as tf from "@tensorflow/tfjs"Â Â // Defining indices, updates and shape const ind = tf.tensor2d([6, 5, 2], [3, 1], 'int32'); const updat = tf.tensor1d([1, 2, 3]); const shp = [6]; Â Â // Calling tf.scatterND() method and // Printing output tf.scatterND(ind, updat, shp).print(); |
Output:
Tensor
[0, 0, 3, 0, 0, 2]
Example 2:
Javascript
// Importing the tensorflow.js library import * as tf from "@tensorflow/tfjs"  // Calling tf.scatterND() method and // Printing output tf.scatterND(tf.tensor2d([5.4, 2.4], [2, 1], 'int32'),             tf.tensor1d([1.8, 4.2]),             [4]).print(); |
Output:
Tensor
[0, 0, 4.1999998, 0]
