The news: A new technique known as “machine unlearning” could be used to teach AI models to forget specific voices. How it works: Currently, companies tend to deal with this issue by checking whether the prompts or the AI’s responses contain disallowed material. Machine unlearning instead asks whether an AI can be made to forget a piece of information that the company doesn’t want it to know. Why it matters: This could be an important step in stopping the rise of audio deepfakes, where someone’s voice is copied to carry out fraud or scams. There's a lack of clear evidence that AI can be a net benefit for students, and it's hard to trust that the AI companies funding this initiative will give honest advice on when not to use AI in the classroom.
