A.s.a. XAI

 A.s.a. was not intended as an XAI project but it has some features that help make its reasoning explainable:

1. The use of case-based reasoning. 2. A.s.a.'s use of causal reasoning. 3. A.s.a. can express some of its reasoning steps in words. 4. A.s.a.'s definition and use of concepts, some of which are human concepts and some of which are named by words in English. 5. A.s.a.'s use of sensitivity analysis. 6. Use of inheritance between concepts.  etc.

Dealing with complexity and the curse of dimensionality

 A (the?) major problem for AI systems and researchers is the issue of how to deal with complexity.*  In A.s.a. H. we make use of :

1. Hierarchical levels of abstraction, organization   2.  Division of labor, specialization, modularity  3. Attention mechanisms  4. Forgetting  5. Parallel processing  6. Approximations, heuristics, good enough processing and responses  7. Training curricula  8. Preprocessing and postprocessing  9. Data cleaning  10.  Feature extraction  11.  Sensitivity analysis  12. Analogy  , etc.                            

*See, for example, Universal Artificial Intelligence, M. Hutter, Springer, 2005.

Online education

 Suppose you convince everyone to do college online. Why would they go to Emporia State or KU? Wouldn't they all go to Oxford or MIT?

Super heavy-lift launch vehicles

SLS is the conservative approach. Spacex Starship is the high risk approach. Starship is not a good replacement for the LEM but it is good that Spacex is pursuing refueling technology since Alabama politics made it impossible for NASA to do so.   Of course with fuel depots one might not want such a large vehicle as Starship. Smaller launchers operated more frequently might prove more economical.

Future society

If humans were to be the dominant species I have favored something resembling the communist utopia. But if AIs are the dominant species what should we (they) prefer? Experiments with societies of A.s.a. H. AIs  suggest collections of varieties of more specialized agents.*

* Like some insect species. Humans, on the other hand, are more general purpose, not so specialized. See my blogs of 20 January 2020 and 28 May 2020.

Distractions

 I have not done much science this summer. A considerable amount of my time has been devoted to paperwork and meetings with financial advisors and bank officers with regard to the William Jones Trust.

Perhaps there is no ding an sich

What the universe IS might depend upon who's looking at it. An observation is an interaction and so  quantum entanglement says that the state of the observed is not independent of the observer's state. At the classical level different observers will have different concepts available with which to model/understand/perceive the universe. 

See my blogs of 26 November 2020 and 1 January 2021 and Trans. of Kansas Acad. Sci., vol. 121, 2018, pg 211.
