AI YOU Creates Digital Twins with Continually Updated Personalities

Researchers have introduced AI YOU, a novel framework designed to create dynamic digital twins capable of evolving their personalities through ongoing conversational interactions. Unlike previous methods that rely on static personality prompts, AI YOU continuously updates a 22-dimensional personality profile using Bayesian updating and conformal prediction techniques. This approach ensures that the digital twin's persona remains consistent and grounded in memory, even during extended dialogues. The system incorporates a periodically refreshed memory anchor and a three-layer cognitive memory to prevent personality drift over time. Evaluations show that AI YOU achieves high conformal coverage and significantly enhances persona fidelity in role-playing scenarios lasting over 100 turns, outperforming static prompting methods. A prototype, AI YOU Town, demonstrates the potential for these digital twins in imaginative interactive environments.
