Explainable artificial intelligence

 My XAI involves producing concept maps like that of my 4 September 2024 blog* and printing out those concepts that A.s.a. H. has active as a function of time as it runs. Of course Asa can form concepts that are not shared by humans. 

* and my Trans. Kansas Acad. Sci., vol. 120, 2017, pg. 108 and blog of 14 November 2017

AI performance improvement

 When you deploy an Asa H AI agent its performance will usually improve over time.*

The performance of a deployed LLM, on the other hand, tends to degrade over time.

* Due to learning new experiences, extrapolation, etc.

An economical space launch system....again*

I'm thinking of something like Shuttle-C (disposable external tank but recoverable/reusable main engines, pumps, avionics, etc. and heat shield)** but with something like the reusable Falcon 9 first stage replacing each of the solid rocket boosters.

* see my blogs of 1 January 2025 and 1 June 2025 

** something like this:

LLM status

I am not a specialist in transformer neural networks or in natural language processing but it is my impression that LLM progress has plateaued. 

Is this serious enough to block Tesla's approach* to controlling robotaxis, robots, and fsd?

* end-to-end neural network

My co-intelligences

 Some specialist AI agents that I collaborate with:

1. natural language knowledge base*

2. machine/process control agent**

3. recommenders***

4. planner/scheduling agent

5. calculators****

6. summarizer

7. A.s.a. H.


* which I use every day.

** see, as an early example, Transactions of the Kansas Academy of Science, vol. 101, pg 132, 1998.

*** which know my wishes/likes/activities.

**** machines have been better than humans at arithmetic for a long time now.

No stand-by or idle

 A.s.a. H. does not "stand-by" or "idle", it's always thinking*, even when its sensory input is minimal. I'd be interested then to see A.s.a. ask any questions "unprovoked."

* Unlike LLMs and many other AIs.

50 years

 I got my PhD in physics 50 years ago. At that time we thought commercial fusion reactors were "right around the corner."
