Observing Whorfian phenomena in Asa H

Language helps to tie some concepts together. Commands issued in english like "obstacle, slow down, turn left" help Asa H to form a link between the actions of slowing and turning, aiding in the creation of a sequence that might be called "dodging." Asa's description and understanding of the world is then written in terms of these very concepts. Language has come to influence how Asa will see its world. Just how strong and important an effect this is remains to be seen.

The emergence of consciousness

Higher level concepts emerge after lower level ones have developed. Concepts of "self" and "consciousness" evolve after/from categories like "sense" and "act." See my 1 January 2017 blog on Asa's expanding consciousness.

The more general concepts

Asa H naturally learns features that co-occur and sequences in time. It quickly learns that servo position feedback, temperatures, acceleration, distance measures, battery charge, etc. form a common cluster which we may choose to call "senses," and loading a file is followed by searching the file and then interpolation and/or extrapolations, a sequence we may choose to label "thinking." Sometimes things like grasp, lift, and move may occur in a sequence and we can name that "act." Some more general concepts occur on higher levels in the memory hierarchy. A sequence of "sense" "think" "act" may define an early form of the "self" concept. If the sequence leads to injury then "pain" or "damage" or "health" is added to the "self" concept. Hand coding can be used to speed up learning of any desired concepts or to make Asa's concepts more closely resemble categories humans know and use.

Root cause

Climate change is just a modern example of the tragedy of the commons. A real solution must eliminate the root cause. The root cause is capitalism. Excessive competition gets in the way of needed cooperation. I've seen this happen time and time again.

In black and white

I've been watching the movie Madiba on BET and the Chappelle re-run on Saturday Night Live. Mandela's story brought home to me the fact that you can't devote your life so completely to a cause and have a normal family life. The same thing is true when you devote yourself so extensively to science.

Chappelle made it clear to me that while a white American might well react to Trump's election like I did in my 9 November 2016 blog, for black Americans it was just same ol' same ol'. I do disagree a bit in that it seems to me HRC really won the election by almost 3 million votes. So Americans didn't vote as poorly as one might think. I also point out that giving a mad man control of nuclear weapons IS different from some other evils that America (the U.S. that is) has been responsible for in the past.

Brain surgery

Hand coding, working from things like my blogs of 5 November 2015, 21 July 2016 and 1 January 2017 I am trying to clean up a set of standardized core concepts that would be shared by all subsequent Asa H agents, regardless of their specializations.

Discrete and continuous

Some aspects of reality appear to be discrete. Matter seems to come in chunks we call atoms. Charge seems to come in chunks. Other aspects of reality appear to be continuous. Distance/length in 3 dimensions, x, y, and z, seems to be continuous. Duration/time seems to be continuous.

Some of our artificial intelligence systems are purely discrete, things like logic programming software run on digital computers. Other approaches to AI can be continuous, things like the dynamic approach to cognition based on differential equations. And there are analog computers and control systems.

While modeling the world Asa H makes use of both discrete and continuous math. Asa can add new categories and attributes/features. It grows a graphical network of concepts. It can also (continuously) adjust the relative strengths of attributes, do interpolation and extrapolation, etc.
