Slide 10.7: TensorFlow.js operations

TensorFlow.js Operations

Tensor Addition
You can add two tensors using tensorA.add(tensorB) function:


<html> <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script> <body> <div id="demo" /> <script type="text/javascript"> const tensorA = tf.tensor([[1, 2], [3, 4], [5, 6]]); const tensorB = tf.tensor([[1,-1], [2,-2], [3,-3]]); // Tensor Addition const tensorNew = tensorA.add(tensorB); // Result: [ [2, 1], [5, 2], [8, 3] ] document.getElementById("demo").innerHTML = tensorNew; </script> </body> </html>

Tensor Subtraction
You can subtract two tensors using tensorA.sub(tensorB) function:


<html> <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script> <body> <div id="demo" /> <script type="text/javascript"> const tensorA = tf.tensor([[1, 2], [3, 4], [5, 6]]); const tensorB = tf.tensor([[1,-1], [2,-2], [3,-3]]); // Tensor Subtraction const tensorNew = tensorA.sub(tensorB); // Result: [ [0, 3], [1, 6], [2, 9] ] document.getElementById("demo").innerHTML = tensorNew; </script> </body> </html>

Tensor Multiplication
You can multiply two tensors using tensorA.mul(tensorB) function:


<html> <script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"></script> <body> <div id="demo" /> <script type="text/javascript"> const tensorA = tf.tensor([1, 2, 3, 4]); const tensorB = tf.tensor([4, 4, 2, 2]); // Tensor Multiplication const tensorNew = tensorA.mul(tensorB); // Result: [ 4, 8, 6, 8 ] document.getElementById("demo").innerHTML = tensorNew; </script> </body> </html>
