02.09.2021 · Using raw TensorFlow without Keras is an option, but I am more comfortable using the PyTorch APIs. An example of a custom NoisyLinear () layer. Notice the two outputs are slightly different. I hadn’t looked at the problem of creating a custom PyTorch Layer in several months, so I figured I’d code up a demo. The most fundamental layer is Linear ().
