Harry Potter - a magic tool for experts to demystify AI
Financial Express Mumbai|December 27, 2023
MORE THAN TWO decades after JK Rowling introduced the world to a universe of magical creatures, forbidden forests and a teenage wizard, Harry Potter is finding renewed relevance in a very different body of literature: AI research.
SARITHA RAI

A growing number of researchers are using the bestselling Harry Potter books to experiment with generative artificial intelligence technology, citing the series' enduring influence in popular culture and the wide range of language data and complex wordplay within its pages. Reviewing a list of studies and academic papers referencing Harry Potter offers a snapshot into cutting-edge AI research - and some of the thorniest questions facing the technology.

In perhaps the most notable recent example, Harry, Hermione and Ron star in a paper titled "Who's Harry Potter?" that sheds light on a new technique helping large language models to selectively forget information. It's a high-stakes task for the industry: Large language models, which power AI chatbots, are built on vast amounts of online data, including copyrighted material and other problematic content. That has led to lawsuits and public scrutiny for some AI companies.

The paper's Microsoft researchers Mark Russinovich and Ronen Eldan, said they've demonstrated that AI models can be altered or edited to remove any knowledge of the existence of the Harry Potter books, including characters and plots, without sacrificing the AI system's overall decision-making and analytical abilities.
