I'm not quite sure if I have it or not. I visualize mostly in 3d but without a specific viewpoint, or more exactly I get a feel from how it would look from various viewpoints simultaneously. I find it easier to mentally see as a 2d picture, something I saw in photo, or on a screen.

If I specifically force myself to imagine how it would look if I was at a specific position looking in a specific direction (i.e. do the 2d projection), I can in-paint in my mind starting from a black canvas, focusing sequentially my attention on a part of the canvas making details appear at the center of attention. I scan the canvas a few times in-painting details, and then I try to mentally take a step back visualize all those various details in a unique coherent picture, by un-focusing attention. It kinda work, but it needs to get into it. It's easier to imagine looking at a photo from the scene I'm trying to visualize.
I noticed my eyes do some REM when I do this. Color and illumination comes last. Closing eyes helps.
I can mentally do a "street-view" experience of my home, moving inside and answer question about details, but I need to focus my attention first on the relevant area.

Those mental exercises are quite funny, not sure how useful they are though. Once you add some moving objects (like pendulums) in the scene in your mind, it gets even harder to make something coherent. Then you can add animals and people, wind. Noises, music. I guess when you add complexity, you must relax your attention to make a coherent global picture, then you get into a flow-like state, and it becomes more similar to a lucid dream.

On the other hand of the spectrum, I'm not quite sure about auras too. It's kind like of synesthesia but for people instead of numbers. I guess the brain hallucinate colors around object/people to make it faster to process. I find it quite unnecessary to hallucinate rather than having a specific feel about the person. And I feel it's quite reductive/intolerant to put/interact with people into a category based on subconscious perception. But I guess that if I was a bouncer, I'll probably be seeing colors around people too.

To conclude this already too long post, I think aphantasia is probably very correlated with hyper-attention.
For those outside the US: 6.5 us mpg = 36 l/100km ... it's funny how different fuel prices have given radically different local optimisations.
As far as I can tell from looking at the code that implements it, and ignoring the training for the moment, the model itself takes a binary vector, and takes the sum of (the characteristic function of) AND's of elements of that vector, and returns whether the sum exceeds a threshold.

So an example model with an input vector `x` might be

x[1] & ~x[2] & x[4] + x[2] & x[4] + x[1] & x[3] > 1

EDIT: okay, so that's the effective evaluation model, but for training purposes, it is stored internally as a series of real numbers for each potential coefficient, and if that number exceeds the "number of states", then it is considered active. So the model above in binary form would look like

+: [1,0,0,1],[0,1,0,1],[1,0,1,0]
-: [0,1,0,0],[0,0,0,0],[0,0,0,0]

But internally this could be represented (with number_of_states == 6) as

+: [7.1,5.0,4.0,8.0 ],[3.7,6.1,5.9,7.8],[8.0,3.0,6.5,5.2]

EDIT 2: Each term apparently is assigned a sign flag, and the threshold is 0, so not strictly an increasing sum.

Do you understand that the difference there is not much bigger than detecting motion gesture, and detecting notion gesture and claiming doing that precisely?

Both things require mm waveradar and some non-trivial DSP functionality to recognise gesture from clutter, and both have to be calibrated to significant precision.

This is the that glaring flaw of current patent system where there can be 20 very similar products, but all covered by different patents with only difference being verbage on the patent.

>China’s GDP has been slowing in recent years as it achieved relative parity with the US and the Eurozone:

This is misleading; the relevant metric for measuring development is GDP per capita, which is only around $8,500 in China, compared to $59,000 for the US and and $33,000 for the EU (https://en.wikipedia.org/wiki/List_of_countries_by_GDP_(nomi...). The average person in China is much poorer than the average person in America or Europe; a significant portion are still subsistence farmers, the only reason absolute GDP is comparable with the US and Europe is that China's population is way bigger. One would only expect growth to slow when China's per-person GDP approaches that of a developed country, not it's total GDP.

The specialist applications of powder metallurgy are awesome, not to mention the fact that lots of refractory metals can only be used with sintered powder (eg tungsten). It should also be pointed out that powder metallurgy parts have long been an important part of engineering (mostly sintered bronze bushings impregnated with grease), and have recently become hugely common as powder gears.

Manufacturing standard spur gears in particular has benefited HUGELY from powder metallurgy. You can use it to make exceptionally accurate and cheap extrudable shapes, and gears have traditionally been hugely expensive and wasteful because you have to cut out the teeth, harden, and final-cut. Powder metallurgy has created an important middle ground- exceptionally cheap medium-quality gears. Now instead of unhardened gears you will always get powder gears, which are better. In places where final-ground gears were overkill, powder gears have come in at acceptable quality and greatly reduced prices. Powder metallurgy is awesome!

>And that is why noone can answer a simple technical question.

Who is "noone"? Some people in a small thread on HN that first read about this today and most of which do not have anything to do with NN or Tsetlin's automata (e.g. startup founders, JS programmers, embedded programmers, and so on)?

Note also that you haven't made any "simple technical question" -- not a specific one that is. Just asked for it to be explained to you, and then rudely complained again when someone did that it wasn't "reasonably" explained.

You also seem impatient to wait for one (considering that you posted 4 hours ago, and most of US is sleeping still), it has to be pronto for you it seems...

Here's also a simple explanation from another member:

"The Tsetlin machine is based on Tsetlin’s automata, the so called finite automata with linear tactics. The are basically counters of rewards (up) and penalties (down) with various strategies of integration, proportionization and differentiation. They have minimum necessary for digital emulation of the perception functionality. They str not only due to Tsetlin but also yo Krinsky, Krylov, Varshavsky. Mikhail Tsetlin is the most prominent creator. It’s the work in the USSR in the 60s. So not new but very elegant!"

>His approach is to do something trivial but bury it in a completely obscure terminology. This technically sorta works on a toy example but not really on more challenging tests. But it is very convincing for people who are not trying to understand what is going on but rather are impressed by technical words and academic rank. That is why it is getting negative feedback here and on other technical forums.

Possibly. Also possible that all the negative feedback are from people who don't understand the math either, and/or are too invested in traditional NN, and is the usual resistance to new ideas.

Apparently you don't have the means to classify it to one or the other case, but you do want to be rude and make a judgement nonetheless.

i think there was at least one language that made rosettacode their official repository for code examples. so all their solutions were vetted by experienced developers.

i believe the rosettacode maintainers would allow adding a note to each example that has been checked. (simply add it to the description of the solution, so that people know which examples are recommended)
That is my heuristic, is it sound? perhaps not. I have said "I will give weightage" not you should not take his prediction seriously.

I think you mean de jure. A mainland Chinese would not go to Taiwanese courts or abide by Taiwanese law, so you cannot say that most living in Qing China's imperial borders recognize the legitimacy of TW's govt.

Internationally, more countries abide by the PRC's One China policy than exclusively recognize TW, so it does not have international de facto legitimacy as well.

De jure... well, that would still be arbitrary. Go further back and one might consider the hereditary Qing successors to be the legitimate rulers. Or you might consider legitimacy to be conferred by the Mandate of Heaven, and by that reasoning China has never been more prosperous than the present in absolute terms, so then the PRC holds legitimacy.
I remember having band practice at our drummer's house when I was younger. The drummers mother and our vocalist knew each other. To reach the high notes, she said to him, you have to "sing higher" and your voice will naturally fail down to where you want to be.

These predications kind of feel like that. Kurzweil was "singing higher" than where we ended up. Just enough that it's a clear overshoot, but not but so much that he's off-key.
It may be that attending such colleges is highly correlated to IQ; I'm unaware of research on that topic. (as closely as my field is related to that topic, highly elite schools tend to be outliers and aren't in the scope of my own activities)

What I can say somewhat definitively is that any such research would be fairly outdated. IQ tests simply are not used at any scale that would be required to study such a correlation, and so if there are recent studies they'd likely rely on sparse data from a small subset of (possibly self-selected & biased) students.

SAT or other standardized scores are a different matter. But as my other comments in this thread state, those tests are very much not designed and calibrated to measure anything beyond 1st year college success. 1st year success does itself correlate with 2nd year, grad rates, etc., but the signal degrades significantly as time goes on.

A Tselin automata returns always true or always false depending on its internal state (wich is basically a counter set during the learning process).

Using one automata per literal per clause you can learn any logical formula in normalized form (the automata tells you if you should include this literal or not).
That section made the paper worth reading for me.

A Tselin machine is a refinement of the formula learning algorithm to get better learning properties, once trained you get a (long) formula (not precisely a logical formula since it uses a sum and a threshold instead of OR to improve robustness).

It is important to note that they manipulate boolean inputs and outputs and, thus, it is not a general alternativ for neural network.

I would point out that his predictions for 2018 included the opinion that Trump would remain President throughout. On hopeful thinking, many liberals would've suggested that Trump's Presidency would not survive 2018. So clearly he feels the changes throughout 2018 have reached a tipping point of some kind.
I would have voted for Clinton (if I were able to, and Bernie wasn't available).

Associations of candidate genes with psychological traits and other traits studied in the social sciences should be viewed as tentative until they have been replicated in multiple large samples. Failing to exercise such caution may hamper scientific progress by allowing for the proliferation of potentially false results [… which may lead to] incorrect perceptions about the state of knowledge in the field, especially knowledge concerning genetic variants that have been described as “genes for” traits on the basis of unintentionally inflated estimates of effect size and statistical significance.[0][1]

>Give buses priority at intersections,

Or just give them the IR transponders that emergency services use to trigger the light in some places and have it go green for the bus rather than red for everyone. You'd accomplish almost the same result with less trade-offs.

Giving one vehicle priority tends to increase complexity and causes a distraction which increases risk of accidents (which clog up the road making the bus late). This is why the modern doctrine for EMTs is to drive in traffic like everyone else and use lights/sirens only in the most time critical cases and when doing so will substantially affect travel time.

Twenty years ago (crikey, that long?), I was a pretty vocal Open Source advocate. At the time, it seemed like the only way to avoid a Microsoft monoculture, and I'm still not sure that wasn't true. But now we're seeing monocultures of corporate-sponsored open source (Chrome/Blink's dominance seems particularly alarming in this sense), and managers who are more reluctant than ever to accept technical solutions which aren't "standard".

I'd love to know how to bring back a bit more diversity to everyday computing. Beyond using niche systems for hobby projects, leverage seems rather limited right now.

Can you share more about this?
I want to push back on this notion a little bit. I think non-waterfall is plenty fine for hardware development. If you structure your product development cycle as a series of (design, build, test, feedback) steps, you get that valuable feedback much earlier than later.

One/one-hundred-off prototypes are expensive but nothing beats the information gained from soldering a board, plugging in connectors, and programming chips directly. You'll do these steps at the end of a waterfall process anyways, and I'd say they're more expensive to alter then. When a problem is found, deciding to bodge wire two pads is the high-cost, low-risk solution to problems found late in the game. Discovering the problem early, fixing it in the schematic, and testing during your next prototype cycle is cheaper during production and risk is mitigated because you're still going to be testing before you ship.

Of course, this is all very much propaganda, and not all shops would follow this idealistic scenario, but I don't think hardware is any more waterfall than anything else.
I suspect a reason why its not that big news in the rest of the world is that this kind of stuff tend to happen. Germany was without a government for almost 6 months, Sweden is still without a government since 9th September last year, and I recall Iceland has a similar situation last election.

What seems more unique to the US situation is that the political turmoil could results in regular employees not getting paid. If we get to the point that people can't pay rent then I am sure it would quickly turn into emergency that international news agency will talk about nonstop until resolved.

Bonds are also debt, though?

The normal operation of bankruptcy law puts bondholders and depositors on the same footing. If the bank is in a position where it can't pay the bondholders the depositors are also at risk.

That's pretty much what central bank insurance gets you. But you can't be free of the counterparty risk of the bank ceasing to operate rendering you illiquid while it's resolved.
This is, as usual for Kurzweil, full of Andy Grove Fallacies [0]: roughly, the premise that everything is a lot like a semiconductor so we can just apply Moore’s Law to biology.

Many/most things are not nearly as simple as transistors and computation are. Nature prefers sigmoids over exponentials anyway, so it’s basically always unrealistic to predict things getting exponentially different unless you have really good priors to let you predict when that sigmoid necks over.

It's funny this should come up, I've spent the last year developing a framework for the construction of CYOA-style adventures on a website I run. It's a creative-writing / creative-expression heavy community, so the hope is that this will go over very well. We're scheduled for our grand release later this month :)

It's got a number of elements inspired by D&D 5e, as well as from Game Books I used to enjoy as a child. Interestingly, it has analogues for many of the conceps in the Squidi post you link to. For example, it's got "encounters" which perform essentially the same thing as GOSUB routines, and has "Expressions" which are calculations that can rely on adventure state and can be used to conditionally hide or unhide particular actions that an adventurer can take.

In case anyone's interested, the reference documentation where you can see our structure and how things work is here: https://www.mycenacave.com/kb/adventure

I'm extremely proud of it.

I highly doubt that advertising a 10 year old anime would be very profitable. If anything it's an ad for the robots. The robots designed specifically to help disabled people.

That’s a pretty charitable interpretation. I would suggest that we’d be in more or less exactly the same spot whether or not kurzweil published these predictions. He didn’t do it to advance the state of the art. Or if he did he’s totally deluded. He was just wrong.
