Function add

Layer that performs element-wise addition on an Array of inputs.

It takes as input a list of tensors, all of the same shape, and returns a single tensor (also of the same shape). The inputs are specified as an Array when the apply method of the Add layer instance is called. For example:

const input1 = tf.input({shape: [2, 2]});
const input2 = tf.input({shape: [2, 2]});
const addLayer = tf.layers.add();
const sum = addLayer.apply([input1, input2]);
console.log(JSON.stringify(sum.shape));
// You get [null, 2, 2], with the first dimension as the undetermined batch
// dimension.
