The forecast of a hurricane definitely requires causal inference, as factors such as the hurricane's strength, population density, and city size can act as confounding variables, influencing both its projected landfall location and its potential category at landfall. @yudapearl

Another intuition why our unit selection is advanced : our objective func is a linear combination of complier,always-taker,never-taker,and defier, while A/B test is a linear combination of (complier+always-taker)(i.e.,treated) and (always-taker+defier)(i.e.,controlled) @yudapearl

Just realized that a Python package, called Causal ML, from Uber implemented a simple version of our Unit Selection model. causalml.readthedocs.io/en/latest/caus… @yudapearl

When estimating causal effects, what you should do if the adjustment variables are partially observable? what you should do if the adjustment variables have high dimensionality? Check our new paper at #AAAI2022 <ucla.in/3o2FL7u> @yudapearl

This Nature article nature.com/articles/s4158… claims to be using AI to increase eligibility of patients for RCT. The word "causality" does not appear, meaning: this application could be a golden opportunity to leverage modern work on "unit selection" as in ucla.in/34mq6Uh

Today, September 1st, marks the 10-year anniversary of the publication of Causality (2009, 2nd ed.) ucla.in/2BDDTLK I am proud to see that the book has stimulated 14,850 citations on Google Scholar and that, oddly, I am still agreeing with everything it says. #Bookofwhy

Another new one in traditional Chinese : ) @yudapearl @Ang_UCLA "因果革命" means revolution of causality.

We had a presentation for our paper "Unit Selection Based on Counterfactual Logic" at IJCAI2019. We proposed an informative selection criterion for how to select the desired group of individuals. The slides is available at web.cs.ucla.edu/~angli/causal/… @yudapearl @Ang_UCLA

Remember Ang Li paper on how to select customers (or patients, or voters) that are most likely to respond to your request/action, though "responsiveness" is an unobserved, counterfactual notion? A revised and improved version is now posted here: ucla.in/2EgRzvl #Bookofwhy

Today, May 9, is Israel's Independence Day. I invite all readers to join me in celebrating the 71st birthday of the country where I learned to speak, and thanking her for what she has contributed to mankind, and for redefining the meaning of "miracle." Happy Birthday Israel !!!!
