Takeaways:

• DADVI is a new approach to variational inference that aims to improve speed and accuracy.
• DADVI allows for faster Bayesian inference without sacrificing model flexibility.
• Linear response can help recover covariance estimates from mean estimates.
• DADVI performs well in mixed models and hierarchical structures.
• Normalizing flows present an interesting avenue for enhancing variational inference.
• DADVI can handle large datasets effectively, improving predictive performance.
• Future enhancements for DADVI may include GPU support and linear response integration.
