Why we dream is one of science's most perplexing mysteries, but a neuroscientist thinks he finally has the answer. Neural networks are a subset of machine learning and are at the heart of deep learning algorithms. Their name and structure are inspired by the human brain, mimicking the way that biological neurons signal to one another. 'There's obviously an incredible number of theories of why we dream,' said Professor Hoel. But a common problem when it comes to training neural networks is that they can become too familiar with the data they've been trained on.
