Researchers at The University of Texas at Austin have developed a method called "machine unlearning" to remove copyright-protected and violent content from generative AI models. This approach allows for the active blocking and removal of undesirable content without starting from scratch. Traditionally, the process required manually removing data and retraining the model. The new method is significant for ensuring responsible use and making generative AI models commercially viable. The research focuses on image-based generative AI models and incorporates human teams in content moderation and removal. This research opens up possibilities for addressing copyrighted and violent content in generative AI models.
