Christmas Carols, generated by a neural network

Neural networks are a type of computer program that imitate the way that brains learn to solve problems. They're used for face recognition, self-driving cars, language translation, financial decisions, and more. I mainly use them to write humor. My process starts with a dataset - something that the neural network has to figure out how to imitate. Rather unfairly, I give it no instructions about whether it's trying to write knock-knock jokes or invent Halloween costumes or begin a novel.
