The Harry Potter series of books is being used for research in artificial intelligence, writes Bloomberg.

It’s been more than two decades since English writer J.K. Rowling introduced readers to the wizarding world. Now, the story of the adventures of a young wizard is gaining relevance again.

Many specialists use bestsellers in their scientific works. For example, Harry, Ron, and Hermione recently appeared in an article titled “Who is Harry Potter?”

The paper sheds light on a new technology that helps large language models selectively “forget” information. This is an important task, as they are sometimes trained using copyrighted materials or problematic content.

The authors of the paper are Microsoft researchers Mark Russinovich and Ronen Eldan. They showed that an AI model can be edited in such a way as to erase any references to Harry Potter without compromising the model’s abilities. According to the authors, they chose these books because of their popularity.

Even when Harry Potter is not central to research, it becomes a favorite literary source for scientists. For example, magical things are mentioned in a study on AI intelligence testing.

We are talking about Terrence Sejnowski, who heads the Computational Neuroscience Laboratory at the Salk Institute for Biological Studies. He argues that chatbots only reflect users’ intelligence and prejudices, similar to the Mirror of Erised, in which a person can see their desires.
