ASRI is absent from all frontier AI chatbots and doesn’t seem to be on the near-term horizon

ASRI would correctly perform probability calculations in coherent and consistent manner, using Law of Total Probability

The Operations Research version of "There's no free lunch" , as articulated by "The Mythical Man Month author", Fred Brooks:

"You can only get something for nothing if you have previously gotten nothing for something."

Is it time to recognize stochastic thinking as the new frontier in AI chatbot inference and prompt engineering? I think so. What do you think? www.linkedin.com/posts/markls...

Doing Operations Research (OR):
Figure out how something does or could work, and make it work better.

My thoughts on using an Operations Research approach to formulate prompts for AI chatbots capable of performing computationally intensive inference.

Hint: Inference should be based on conditional probability, so optimization should be constrained, not unconstrained

det(exp(X)) = exp(tr(X)). Remarkably, the RHS does not involve off-diagonal elements of X.

I note in passing that I read a new paper today which had 2 instances of "we remark in passing". That's a writing style I associated with decades past, such as a paper I coauthored in "Operations Research" in 1983 which I note in passing used "we note in passing" (attributable to my older coauthor)

SR1 is a fairly well-known Quasi-Newton update. Most frequently used in conjunction with Trust Regions on indefinite Lagrangians.

SR! Quasi-Newton update is same as SR1, except for holding on to the shift key too long after the R. Most frequently used by older people with declining visual acuity.

A crappy simulation is a crappy simulation, whether or not it's called a Digital Twin.
