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 .train.sgd() function is used to build a tf.SGDOptimizer which utilizes stochastic gradient descent.
Syntax:
tf.train.sgd(learningRate)
Parameters:
- learningRate: The stated learning rate which is used in favor of the SGD algorithm. It is of type number.
Return Value: It returns tf.SGDOptimizer.
Example 1:
Javascript
// Importing the tensorflow.js library import * as tf from "@tensorflow/tfjs" // Declaring learningRate const learning_rate = 0.02; // Calling train.sgd() method const res = tf.train.sgd(learning_rate); // Printing output console.log(res); |
Output:
{ "learningRate": 0.02, "c": { "kept": true, "isDisposedInternal": false, "shape": [], "dtype": "float32", "size": 1, "strides": [], "dataId": { "id": 1298 }, "id": 1192, "rankType": "0", "scopeId": 1251 } }
Example 2:
Javascript
// Importing the tensorflow.js library import * as tf from "@tensorflow/tfjs" // Calling train.sgd() and sin() method console.log(JSON.stringify(tf.train.sgd(tf.sin(45)))); |
Output:
{"learningRate":{"kept":false,"isDisposedInternal":false,"shape":[], "dtype":"float32","size":1,"strides":[],"dataId":{"id":1316},"id":1207, "rankType":"0","scopeId":1269},"c":{"kept":true,"isDisposedInternal":false, "shape":[],"dtype":"float32","size":1,"strides":[],"dataId":{"id":1318}, "id":1208,"rankType":"0","scopeId":1269}}
