Higher-order features

I have usually described A.s.a. H. as learning layers of categories/concepts. (In the form of vectors.) After learning a set of first-order features A.s.a. H. May then learn the ANDing together of some of these on the next level in its hierarchy. Are these concepts or second-order features? Second-order features are thought to be important for doing things like facial recognition. Interactions among features may be represented by such higher-order features prior to their use to define some concept.

Alternate realities, metaphysics

Quesada argues* that various philosophers have used alternative logics to build alternative metaphysics. Idealistic, materialistic, non materialistic, dualistic, noneist, etc.  Plato employs a fuzzy logic. Aristotle created classical logic. Plotinus employs fuzzy and paraconsistent logics. Hegel employs dialectical logic. Routley creates neutral logic....

Why build theories?

For genetic algorithms and evolution* to get from some state A to some distant state B requires that one or more quasi-continuous paths exist from A to B through some intermediate states C, D, E, etc. The creation of theories of the world can allow for larger designed leaps from A to B.
Theories also are a compact way of organizing knowledge speeding up search and reducing the memory capacity required.

Lotus eaters

With a scalar utility an AI like Marcus Hutter's AIXI might evolve toward lower intelligence if it resides in a sufficiently simple and benign environment.* Indeed, its the harsh world we find ourselves in that has forced life to develop  mind.  A society of A.s.a. H. agents with their vector utilities (at least one component of which values mental prowess of some sort) will always seek to produce some offspring with increasing mentality.**

Hierarchically structured general intelligence

I notice that Paul Yaworsky of the Air Force Research Laboratory has argued for the hierarchical organization of general intelligent systems.* He seems to imagine something like A.s.a. H. but he offers nothing in the way of algorithms or other detail.

Robot brain transplants

Some LEGO robot designs allow you to readily remove the NXT or EV3 brick without otherwise disassembling the robot.* One can then swap in an Arduino or Raspberry Pi in its place. (Given a suitable shield.) The Raspberry Pi could make use of a neural compute stick for example. Arduino has sensors for humidity, odor, rain, barometric pressure, etc.

* Damien Kee's RileyRover being one example.

Laws of nature

We describe the world and the way it evolves, the patterns/regularities that we see in it.* We take note of our part in this. We try to do this in as compact a fashion as possible. These descriptions may make use of sentences in a natural language, equations in a system of mathematics, diagrams and icons or what have you.** By a "law of nature" we simply mean a rather good description of some pattern(s) we see in the world, some regularity.

* See my blog of 1 Sept. 2012.
** Maybe we might use a pattern of musical notes. Certainly we use spoken sentences, lecture. (Spoken language may have come a million years before written language.) Musical patterns may be well suited to expressing and conveying things like energy, excitement, and emotions.
