Nice to discover Judea Pearl ask a fundamental question. What's an 'inductive bias'?

All Biological life on earth is possible because of a discrete digital mechanism of preservation and replication.

The mechanism of signaling between the superorganism we know of as bacteria and its ongoing war against viruses is through a digital mechanism.

The source of innovation in biology is in this milieu of microbiome and viromes that are ubiquitous in every complex multicellular organism on earth. Humans are walking ecologies and cannot survive stripped of these ecologies.

We can picture this as a cloud of digital interaction that surrounds all of us.

The cells of multicellular creatures however do not communicate in the same way as bacteria. The DNA of mammals are sequestered from daily activity so as to prevent wear and tear.

Those trained as physicists strive to see the world in terms of symmetries and processes that break symmetries. It's a meta-principle that guides their questioning.

This is very different from how many are taught physics (I guess in high school). We come to know of physics as consisting of laws that describe the behavior of inanimate (or is it indifferent) objects? These laws are described as expressions of equalities (i.e. equations).

But laws like Newton's f=ma or Einstein's e=mc^2 are derived from a higher meta principal. These principles are known as conservation laws. Energy, momentum, angular momentum are all conserved.

Conservation laws however are also derived from a higher principle. A conservation law implies that something remains the same as the situation of study change. Energy conservation implies that it is that something that does not change in time. In short, a symmetry.

This idea that laws are derived from conservation principles that is derived from symmetries is at the core of the study of physics. The laws of physics are only authoritative as long as they don't violate a higher principle. Ultimately, that principle is all about symmetry.

My attempt to map the research *doctrines* of various groups working on Artificial General Intelligence.

Although one might see names of individuals here as well as organizations, take it just as identification of the organization behind the person and a very narrow slice of their overall research portfolio.

Here is a @swardley map that captures the relationship of doctrine with other individual and organizational processes.

We can capture a party's doctrine by either an explicitly stated agenda or an aggregation of the kind of approach that is pursued. A doctrine is an invariant property of the overall behavior of a party.

In this map one can see the conflict between different parties (compare @garymarcus with the deep learning folks).

Star Wars has a simple dichotomy between good and evil. But as the stories have evolved, the nuances between these distinct poles also has acquired a richness that is hard to dismiss.

In the latest trilogy, we discover a dysfunctional civilization even after the defeat of the empire. The argument that the remnants of the empire make is that the galaxy stills seeks a need for order. Order and chaos are at seperate poles where evil is aligned with order.

We know however from D&D alignment charts that good and evil, order and chaos can exist in many combinations:

It is also interesting that the Sith (the Evil sorcerers) only come in pairs as opposed to the Jedi that can be entire communities. Apparently, to sustain evil one has to restrict agency and individuality to just a few. A community of evil-doers very quickly turns on itself.

So at one extreme we have evil, order, individuality and at the other we have good, chaos, collective. Which brings up the question, what is the definition of evil and good? Something that we took for granted ever since the first Star Wars movie.

Abduction is that thought process where we renew our past, question our present, and reimagine our future.

It was C.S. Peirce, a century ago, that coined the use of this term to describe a thought process that would convey hypothesis making.

A little over 50 years ago, proponents of Artificial Intelligence, proposed that deduction would be the core feature of human intelligence. This idea was driven by the bias towards formal logical systems and the emergence of computers.

This approach was in stark contrast to cybernetics (introduced a decade early) that proposed that dynamical systems were a model for intelligence. The descendant of this approach was coined as artificial neural networks.

This dynamical systems approach was later understood as being similar to an induction based thought process. Deep Learning leads to what can be characterized as Artificial Intuition.

@The_Rumpus is open for essay submissions until February 28, so here’s a #RumpusEssays thread in which our amazing editors share what they would like to see in submissions. Give them a follow and send your essay our way via @submittable

Features Editor @happiestwerther is “still (forever) in love with the researched essays that teach me something about a subject while I also learn about a narrator.” #RumpusEssays

Assistant Features Editor @sarahkasbeer would like to see “essays with unexpected engines / innovative structures / emotional and intellectual depth / good ole narrative tension.” #RumpusEssays

Features Editor @kaytaybayy: “I'd love to see essays that are imbued with kinetic energy. I don't care what they're about. Just sweep me into your experiences and thoughts. Compel me to shake my dust off.” #RumpusEssays

Asst Feat Ed @DJ_theoretical: "I’d love to read about that weird, niche topic you’re obsessed with. Your Pog collection, those ribbon candies that seemingly only grandmas buy, your new obscure hobby. Distract me from the horrible big picture with your hyperfixations."

@jeffreyatucker In the end, it is all a natural consequence of a very human foible, namely that we all do everything we can to blame anybody or anything else for our problems, if we can get away with it. It's the reason why rulers start wars to squelch domestic dissent - macro and micro the same

The very notion of the germ theory of disease revolves around this and while it is good for selling medical interventions, treatments and pharmaceuticals, it is no good for either personal health, or public health in any way. We need to start looking at health on a holistic level

More of a systems approach to health would get us to see that the whole instinct to stamp out viruses, like the very counter-factual notion of "zero Covid," and other nonsense, are driven by this need to blame somebody or something else for our problems, so we can have our cake

and eat it too, i.e. we can pass the blame to others and go and kill them, be they bugs or other people (lockdowns???). The results are disastrous for health on both a personal and a public level, and we continue on a path of assured self-destruction. But times are changing, now.

Lifestyle Medicine @aclifemed provides the new paradigm, more of a systems approach to health, in which personal responsibility for our habits comes first, starting with nutrition. Immune systems become depressed by fatigue, stress, inner conflict, malnutrition and so on. Change
