TensorFlow has a lot of machine learning libraries and is well-documented. It provides a few key functions and ways for doing so. TensorFlow is sometimes referred to as a “Google” product. A wide range of machine learning and deep learning algorithms are included. For handwritten digit classification, image recognition, word embedding, and the generation of other sequence models, TensorFlow can train and run deep neural networks.
Installing TenserFlow.js: There are following two methods by which we can install and use TenserFlow.js.
Method 1: We can use CDN link to run Tensorflow.js code without installing it. Add the following CDN link into the script tag to the head section of the HTML file.
Method 2: We can install it using npm. Before installing TensorFlow.js through npm, first, make sure you have installed Node.js and npm.
npm install @tensorflow/tfjs
Let’s understand the working of TenserFlow.js using an example.
Example: In this example, we create an input tensor and weight tensor and pass it to the bincount function and see how bincount calculates the value for the output tensor using Tensorflow.js tf.bincount() Function.
// Importing tensorflow.js library import * as tf from "@tensorflow/tfjs" // Initializing the input const geek_input = tf.tensor([1, 2, 9, 6, 5, 4, 7, 4, 7, 4, 3], [1, 11], 'int32'); // Printing Input tensor console.log('Input tensor: ',geek_input) // Weight and size for the bincount const geek_Weight = tf.tensor( [0, 2, 5, 8, 9, 3, 5, 5, 3, 8, 2]); const geek_size = 8; // Applying bincount to input tensor const r = tf.bincount(geek_input, geek_Weight, geek_size) // Printing result console.log("Output tensor: ", r)
Input tensor: Tensor [[1, 2, 9, 6, 5, 4, 7, 4, 7, 4, 3],] Output tensor: Tensor [0, 0, 2, 2, 16, 9, 8, 8]
