Researchers have developed WALLA, a novel family of decentralized aggregation mechanisms for Large Language Model (LLM) predictions. WALLA allows models to report predictions alongside learned wagers, which are then used as weights for aggregation. This approach ensures incentive compatibility for predictions and aligns optimal wagers with a model's expected score advantage, even without access to private model information. Experiments demonstrate that WALLA achieves predictive performance comparable to centralized methods while enabling decentralized learning and advantage-aligned aggregation. AI
IMPACT Enables more robust and incentive-aligned aggregation of predictions from diverse LLMs in decentralized settings.
