Distribird: Literature-Informed Prior Distribution Design for Bayesian Model Calibration
TL;DR
Distribird is an automated web application that generates literature-informed prior distributions for Bayesian model calibration, addressing the common reliance on uniform priors. It effectively matches the quality of prior distributions produced by advanced language models while ensuring transparency and data privacy.
✦ Why It Matters
Start using Distribird to create reliable prior distributions for your Bayesian models today.
Key Takeaways
- Utilize Distribird for automated prior distribution generation.
- Ensure transparency by tracing priors to specific literature sources.
- Maintain data privacy with local language model calls.
- Avoid out-of-scope requests to enhance prior reliability.
How It Works
Distribird operates by taking a parameter name, physical description, and domain context to search relevant literature. It extracts reported values, weights them based on domain relevance, and fits a probability distribution using AIC model selection.
This multi-agent approach streamlines the process of creating informative priors, which are essential for accurate Bayesian calibration.
