You’ll notice a few key differences though between OneHotEncoder and tf.one_hot in the example above.. First, tf.one_hot is simply an operation, so we’ll need to create a Neural Network layer that uses this operation in order to include the One Hot Encoding logic with the actual model prediction logic. Second, …
