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

 I crucial step on the road towards AGI is a richer vocabulary for reasoning about inductive biases.
@yudapearl explores the apparent impedance mismatch between inductive biases and causal reasoning. But isn't the logical thinking required for good causal reasoning also not an inductive bias?
An inductive bias is what C.S. Peirce would call a habit. It is a habit of reasoning. Logical thinking is like a Platonic solid of the many kinds of heuristics that are discovered.
The kind of black and white logic that is found in digital computers is critical to the emergence of today's information economy. This of course is not the same logic that drives the general intelligence that lives in the same economy.
Digital computers do not have the inductive biases to navigate the complex and messy world of life. Look around, have you seen a machine with the autonomy of a honey bee? They simply have no grounding in life.
General intelligence emerges out of things that are alive. To construct a synthetic general intelligence requires the kind of algorithm that organically grows itself from the inside out.
Which requires the kind of inductive biases that are organic in nature. https://t.co/64gYeKBtI2
So what this reveals is that an inductive bias is an emergent feature of a complex process. Just like the wetness of water. It is interesting to identify these biases, but they aren't the process themselves. They are how we describe the process.
Things that our brains can identify are things that exhibit recurring patterns. We feel the wetness of water because that wetness repeats itself every time we feel water. This causation invariance in nature forges the causality reasoning necessary for navigating a messy world.
An inductive bias is the identifiable recurring thought process (i.e. habits) the brain has developed in the process of its own constructive development while growing into this world.
This said one should never mistake the map from the actual territory. A cognitive bias developed by too many is to confuse the two.

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.

Damasio in his book 'The Strange Order of Things' argues that the core of condition lies in homeostasis. I agree with this generalization. But let me work out in a tweet storm how consciousness relates to homeostasis.

Human consciousness is related to awareness of surprising or threatening observations. It's an error-correcting mechanism that lends attention to discrepancies of our expectations of the world.

The mind is composed of many layers of cognition. Also, its massive parallelism implies reducing the conditional checks required for error correction.

To do this, consciousness is engaged only in a time-sliced manner in a periodic manner. The majority of time spent is in unconscious activity with only periodic activation of the conscious error-correcting process.

The system 1 unconscious intuitive mechanism minimizes the effort of performing error correction. It is automated and driven by habit. It is like a river flowing without obstructions.

Conscious and conscience are two words that share the same origin but mean two different things. The bias against explanations of consciousness comes from the conflation of these two words.

In addition, the question of free will is also adjacent to the notion of both consciousness and conscience. The ideas of consciousness, conscience, and free will serve as the foundation of justice in our civilization. (care to add another?)

So when we see people fail to condemn an act that is morally repugnant, we wonder if they have a conscience. But we don't wonder if they are conscious. When we incarcerate a person, we ask if they had "free will" but we inquire if they were 'conscious' during the crime.

The presence of consciousness and free will imply sentience. Which is the same as conscious and sounds just like a conscience. Our biases have muddled all the words together to likely mean the same thing.

The words that we use today continue to evolve. The same word can have a different meaning in the past. The word empathy is a recent word invented in the early 1900s. Originally it meant to place oneself from the viewpoint of a thing. Today we don't use it in this way.

Constructivism is perhaps the most important idea that will shape the future of humanity. The ills of society are a consequence of the willful ignorance of constructivism.

There are two important definitions of constructivism, one comes from mathematics and the other from psychology. The mathematical definition leads rejects the law of excluded middle. It's relevant in understanding causation.

The psychological definition: "Humans actively construct their own knowledge, and that reality is determined by our experiences as a learner."

The models of causality that our brains invent to navigate the world is a consequence of our progressive development in the world we live in. Robert Kegan calls his theory constructive developmental theory to emphasize two important aspects of cognitive growth.

Cognitive growth is constructive as explained above. It is also developmental in the sense that our mental models of the world make abrupt changes as we grow in maturity. The symmetries in our models break and lead to new symmetries.

I woke up realizing that there is something very wrong with thinking in categories and classifications. Many people accept the idea that this kind of thinking is at the core of abstract thought.

Douglas Hofstadter argues otherwise in a very thick (not dumb in the Brit sense) book of his ('Surface and Essences') where he argues that analogy is at the core of thinking. You'll have to read his book, specifically the last chapter to understand what he means.

The problem with categories is that they create artificial boundaries that are too crisp. But we know that when we master any subject that there is a distinct fluidity between concepts. The master seems wrong from a by-the-book novice because he keeps on breaking definitions.

Analogy making employs the tacit knowledge gained through experience to adroitly navigate between similar and competing concepts. A master has an intuitive feel of the vocabulary he employs to create expressions that have previously never been heard.

Biological brains feel their way through their realities. Something feels like red because our interactions with that thing feels the same as if it was red. We do not see the color red, we feel the color red. There is no red in this picture:

Would anyone like to admit why he cc'd himself in an email Wei Dai would see at ibiblio's host address? I have a few ideas.


was the .ae ccTLD a nod to Tim Berners-Lee/registries that issue top level country code domains? Is that why Tel Aviv is a place I commonly find OTC/Bitcoin related companies and DAC/dev protocols and operations based? Why UAE/Israel have opened commerce bilaterally in 2020?

Bitcoin is worldwide P2P software and growing into a network of the same ilk, what it can send without interference we can't even grasp yet. Even if you don't like another person, or their religious beliefs, bitcoin doesn't care. I lived through 9/11, my friends died in war.

But even I don't want Bitcoin just for the people I am more likely to have similarities too. And in working with the @_Devcoin guys for a few years now, officially since 2020 - I realized people from all spots on this globe and I share much more in common than everyday Americans.

And I haven't turned my back or spurned Americans either. I'm just saying we need to change our mindset. We want things but we won't admit it takes a whole world to pull off what it is we seek. The media is to blame for this but I also think we're at the point for grownups to act

One fascist to watch in 2021 is Joseph Charles "Oakman" Golinske of SE MI. He's been a Proud Boy for a couple years, but took a break recently from the group and promotes himself through the "Oak Nation" channel on Telegram.


Most people may be familiar with him as the tall guy in the Proud Boys bridge shot, from their August 17, 2019 attack on Portland, which featured an American Guard bus trying (and failing) to bludgeon antifascists with hammers.


He was also with his g/f at the time (Dominique Tota, left of Tarrio), and that's definitely a twitter account folks will want to block/report because he posts on it.


He's been plenty active at the pro-Covid/anti-mask/ReOpen protests in Lansing MI, seen here with Jerry Wayne and an effigy of Gretchen Whitmer, who his militia friends tried to kidnap and publicly execute.


Outside of the Proud Boys, his solo "career" with Oak Nation features the same misogyny, classism and gateway to far-right domestic terrorism the Proud Boys themselves feature. Here's him peddling oxychlorinque and bragging about harassing service workers.

The common understanding of propaganda is that it is intended to brainwash the masses. Supposedly, people get exposed to the same message repeatedly and over time come to believe in whatever nonsense authoritarians want them to believe /1

And yet authoritarians often broadcast silly, unpersuasive propaganda.

Political scientist Haifeng Huang writes that the purpose of propaganda is not to brainwash people, but to instill fear in them /2


When people are bombarded with propaganda everywhere they look, they are reminded of the strength of the regime.

The vast amount of resources authoritarians spend to display their message in every corner of the public square is a costly demonstration of their power /3

In fact, the overt silliness of authoritarian propaganda is part of the point. Propaganda is designed to be silly so that people can instantly recognize it when they see it


Propaganda is intended to instill fear in people, not brainwash them.

The message is: You might not believe in pro-regime values or attitudes. But we will make sure you are too frightened to do anything about it.

I shared this on my FB page and asked, can ya really blame him?

I was half kidding. I also assumed someone would think of what I did pretty quickly and waiting for the comment to mention what I assumed was obvious.

The timing. I was sure someone else had thought of it.


But no one did. 20+ comments in people discussed the morality or bad sense or libertarian perspectives. Someone even said I’m thinking about doing that. No one said what I thought was obvious. Have you thought of it? Is it obvious to you?

Here’s a clue...recognize it?


How about this?

Right, screw it. Here's a thread on *that* FBLive by Alex Cairnie about #Govanhill. Lets do a watch-through shall we? (Mind, I'm a resident of Govanhill, and a sociologist. I'm also 5'3, and a visibly queer woman so if half his claims are true I should be living in terror)

00:30: Welcomes viewers and uses points out that his videos are only getting attention b/c they're 'horrific'. Directs folk to his Youtube page. So already clout hunting.

1:08: "I've been warned to stay out of Govanhill. I'm a marked man" (proceeds to use a beanie as a disguise)

1:30 "Laughing and joking aside, here's somebodys front garden." Proceeds to show litter and claim its thrown from windows and this is 'common'. I know a handful of streets with litter issues like this, but its neither common nor unique to #govanhill and other deprived areas.

2:10 "Don't be under any illusion I'm only showing you the bad bits" - only shows you the bad bits.

3:45: He's had offers of help, but hes said no because hes not responsible for 'anybody elses safety' Good lord.

5:01: "Its not that bad. But its not all good either" -Correct

6:00: TW: child abuse - He starts claiming to have been contacted by a health professional and told about child abuse 'in the area'. Huge ethical issues here as the 'professional' who has 'been in the game a long time' is reporting to Facebook Dude and not authorities.

If an employer is willing to be abusive to you prior to hiring you, when you have maximum leverage and they are maximally incentivized to play nice, I think that gives you *extremely actionable* signal as to how they'll treat you when you're working there and dependent on them.

For candidates: evaluate prospective employers accordingly.

For startups employing e.g. engineers: given that your candidates should evaluate you accordingly, be *extra special* careful to operate like professionals with regards to e.g. interviewing, offers, and negotiation.

"Can you be more explicit about 'abusive' here?"

Not without violating a confidence, but as someone who has been on hiring side of table and is a capitalist, there are *clearly* things you could do which would be "sharp operating, but we're all sharp operators" in some contexts.

Hiring employees is often not one of those contexts. The nature of the relationship, the asymmetry in power, and the social contract strongly counsel you to be a lot better there than you are minimally required by law / contract.

A thing which aesthetically frustrates me is that a lot of the things I've heard companies do here serve *no legitimate business purpose.* In some cases it's getting tens of dollars of advantage. TENS! On an engineering candidate!

Keep dwelling on this:
Further Examination of the Motif near PRRA Reveals Close Structural Similarity to the SEB Superantigen as well as Sequence Similarities to Neurotoxins and a Viral SAg.

The insertion PRRA together with 7 sequentially preceding residues & succeeding R685 (conserved in β-CoVs) form a motif, Y674QTQTNSPRRAR685, homologous to those of neurotoxins from Ophiophagus (cobra) and Bungarus genera, as well as neurotoxin-like regions from three RABV strains

(20) (Fig. 2D). We further noticed that the same segment bears close similarity to the HIV-1 glycoprotein gp120 SAg motif F164 to V174.

Tips for AI writers:

1. Spend 30% of your effort on skimming all student ML papers (e.g. Stanford NLP CS224n) the past 3 years and prototype your favorites

The idea is everything. Pick an area you are interested in and ideally something that has a visual aspect to it

Most of my 'on the top of my mind' ideas were bad in retrospect. Skimming 100s of student papers will give you an overview of what's interesting.

Student papers are overlooked, easy to understand, and have good compute constraints.

2. Spend 30% on your effort on coding

Create an edge to the project. Apply it to something new and use FastAI or Keras to improve the accuracy with 5-30%.

3. Spend 30% writing an in-depth article

Have a north star article in terms of structure and quality. Find something that stretches you to your utmost capability. I used @copingbear’s Style transfer article:

4. Spend 10% marketing your project

Invest a week in studying the strategies to rank on sites like HN and Reddit, then use them. If you have an interesting result and a great article, you've done the hard work.
