Researchers introduce a framework for evaluating whether AI creative systems cause population-level diversity collapse, where individual output quality improves while collective idea similarity increases. Testing three frontier LLMs across creative tasks, the study finds they fall below diversity parity with humans and proposes design interventions to mitigate crowding effects at development time.
Researchers propose a novel metric called 'Decan' for measuring diversity in AI-generated creative outputs using in-context learning and language model probabilities, achieving 84.6% accuracy on benchmark tests. The approach detects mode collapse and diversity loss across training stages without requiring specialized embedding models or human annotation, offering a practical tool for evaluating generative AI systems.
Researchers propose HERec, a hyperbolic-geometry-based recommender system framework that balances content exploration and exploitation while mitigating information cocoons. The system combines semantic-enhanced hierarchical mechanisms with automatic clustering to improve diversity by 11.39% and utility by 5.49% over existing approaches.
