Model decomposition efforts

 An (isolated) world model is required for a number of AI applications. So we would like to separate world model* from  agent** model, action model, any pre and post processors, etc. Specialist A.s.a. agents do this to some (limited) degree and even (partially) decompose the world model into specialized submodels*** (i.e., knowledge organization). The mechanisms at play in that case are the specialized (and limited) training curriculum plus the subsequent tasks and work environment selection.

GPT passes minimum Turing test

Although I have been critical of both LLMs and Turing tests it is still interesting to see Jones and Bergen's paper.* I generally do not think science is about tests, benchmarks, and metrics. A number of specialists and organizations have been rather premature in switching from doing science to doing engineering. Work done in industry tends to be rushed, seeking a product and a profit. Pure science is then best done in academic institutions. Of course the capitalists are trying to turn everything into a business including universities. This is not helpful.

Tingling sensation

Vibration can cause Lego bricks to separate enough* to allow pain sensor contacts to lose connection. Continued vibration then causes bouncing contacts, a "tingling" sensation is recorded.

US Supreme Court opinion

 So let me get this straight. Aren't they saying that Joe Biden can have seal team 6 assassinate Donald Trump tomorrow and he (Biden) will be insulated from criminal prosecution because he is the current president? That's nuts. The GOP has a lot to answer for. I fear for the future of my children and grandchildren.

Is this a new Gesetz zur Behebung der Not von Volk und Reich?

Concept grounding*

What sensors are needed to ground the core concepts learned by an intelligent robotic agent**? For some time I simply added sensor types as soon as they were available for use***. But in retrospect I believe that essential ones were:

force sensors, accelerometers, temperature sensors, light sensors, color sensors, gas sensors, anemometer, gps sensor, rain/water sensor, microphone and speaker, humidity sensor, voltage sensors, current sensors, ultrasonic and/or IR range finders, line sensor, servo/motor encoders, and neural network preprocessors****.

Combinations and sequences of these raw input signals together form primitive core concepts.

* Rather than symbol grounding.

** Or society of agents. 

*** For example, my blog of 1 October 2015.

****Possibly classifying input from cameras.

A.s.a.'s values

In our early publication* A.s.a.'s value module was placed at the top of the case/concept hierarchy. This can be true early in training and/or for small agents**. But as training proceeds more and more concepts are acquired/created and these are chained and the hierarchy grows upward. I.e., our values need not be our deepest/most abstracted concepts**.

Furthermore, in the light version of A.s.a. H. 2.0 published in our 10 February 2011 blog we value pattern occurrence frequency and pattern size on each level of the hierarchy.

Another argument for vector utility

Diversity. There are multiple niches, multiple ways to improve a creature's fitness and increase its chances of survival and spread. Beneficial traits, different adaptions, like protective coloration, larger brains,  etc.  Different creatures may find very different ways to improve.
