Inference by multiple observers

Key Points

• To create a framework for analyzing inference models involving multiple observers, especially in multiverse contexts.
• Developed a probability space based on Kolmogorov’s axioms.
• Outlined the Sleeping Beauty problem as a toy model for comparison.
• Compared main competing approaches within the established framework.
• Clarified the characteristics of inference models involving multiple observers.
• Showed how established approaches differ in handling observer scenarios.
• Provided precise comparisons of inference outcomes from competing models.
