TensorFlow.js Operations (Cont.)

Tensor Division
You can divide two tensors using tensorA.div(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([2, 4, 6, 8]); const tensorB = tf.tensor([1, 2, 2, 2]); // Tensor Division const tensorNew = tensorA.div(tensorB); // Result: [ 2, 2, 3, 4 ] document.getElementById("demo").innerHTML = tensorNew; </script> </body> </html>

Tensor Square
You can square a tensor using tensorA.square() 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]); // Tensor Square const tensorNew = tensorA.square(); // Result [ 1, 4, 9, 16 ] document.getElementById("demo").innerHTML = tensorNew; </script> </body> </html>

Tensor Reshape
The number of elements in a tensor is the product of the sizes in the shape. Since there can be different shapes with the same size, it is often useful to reshape a tensor to other shapes with the same size. You can reshape a tensor using tensor.reshape():


<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 = tensorA.reshape([4, 1]); // Result [ [1], [2], [3], [4] ] document.getElementById("demo").innerHTML = tensorB; </script> </body> </html>

My wife and I were out to dinner and the waitress started flirting with me.
“She obviously has COVID,” my wife said.
“Why?” I asked.
My wife replied with a sneer, “Because she has no taste.”
