Neural nets are a popular technique in Artificial Intelligence based on simplified models of neurons and interneuronal connections gathered from brain research. Ray Kurzweil describes them pretty well here:

One basic approach to neural nets can be described as follows. Each point of a given input (for speech, each point represents two dimensions, one being frequency and the other time; for images, each point would be a pixel in a two-dimensional image) is randomly connected to the inputs of the first layer of simulated neurons. Every connection has an associated synaptic strength, which represents its importance and which is set at a random value. Each neuron adds up the signals coming into it. If the combined signal exceeds a particular threshold, the neuron fires and send a signal to its output connection; if the combined input signal does not exceed the threshold, the neuron does not fire, and its output is zero. The output of each neuron is randomly connected to the inputs of the neurons in the next layer. There are multiple layers (generally three or more), and the layers may be organized in a variety of configurations. For example, one layer may feed back to an earlier layer. At the top layer, the output of one or more neurons, also randomly selected, provides the answer.
The Singularity is Near, Ray Kurzweil

What hit me as I was reading this was how eerily close is society (as in human society) to a neural net. Think about it. Have you ever wondered how there are so many great and worthy causes being fought out there that you are not taking part of? You read, listen, think, and sometimes chat about them (you’re adding up the signals coming into you), but the signals simply do not exceed your (mostly random) threshold, and you don’t “fire”, you don’t act, your output is zero. (Street children and the EFF are the first examples that come to my mind, what are yours?)

Take me, for example: after many years of almost total political apathy, I’m close to releasing a web-app about Mexican Politics —in other words, I’ve become political (!)— because in the previous weeks several inputs conspired (somewhat randomly) to spur me into action. I’m an excited neuron in this weird, tragic brain that is Mexico and I only wish that I can get my next layer of neighboring neurons to fire.

Here’s a parting thought: media (and particularly ads) are the neurotransmitters of the hive mind.

The review itself is long and, though interesting at times, overall not that good, but there was a quiet, demure paragraph in it that kept me laughing the whole (did I say it was long?) review. Today I reread the paragraph in my notes and I’ve had a smile in my face ever since. This one’s a keeper:

A huge report was issued by the National Center for Health Statistics. It covered the topic of teenage oral sex more extensively than any previous study, and the news was devastating: A quarter of girls aged fifteen had engaged in it, and more than half aged seventeen. Obviously, there was no previous data to compare this with, but millions of suburban dads were quite adamant that they had been born too soon.

To someone who dropped out of college and has argued along this lines to defend his decision, who has been playing with online reputation systems for a while now, this comment by Alex3917 —originally posted here in response to Paul Graham’s newest essay— was an epiphany, tying and explaining it all together:

So lately I have been thinking a lot about “qualified experts,” as mentioned in the article. Credentialism became prominent in the 20s because of advances in transportation technology. Before WWI everyone lived in the same town their whole lives, so anyone could vouch for you. Then after WWI there was increased mobility, so no longer could your neighbors provide the credibility needed to get a job or get startup funding. Thus college stepped up to fill the role of the middleman. This was essential to keep society functioning, although certainly credentialism hasn’t done much for the learning aspect of college.

Today, however, we have the Internet. Everyone is linked to everyone and anyone can vouch for you. I can email the management of any company and assuming I follow basic email etiquette I can usually get a response. As digital identity improves, everyone will be able to vouch for you based on the information you are supplying about yourself online. For example, PG has his essays and one of his books on his personal website. Surely this is as meaningful as a college degree.

Also, college credentialism is a hierarchy because you have one person making value judgements about many people. Anyone who knows anything about network theory knows that networks are more powerful than hierarchies, because Metcalfe’s law trumps Sarnoff’s law. Thus college supplied credentialism is much less effective than what we are capable of reaching if we use the Internet. This is why many of the “qualified experts” are so imcompetent, because hierarchies are so much weaker than networks.

Anyway, if someone wants to make a sh*tload of money I’d suggest developing some tools for the Internet that start to fill the credentialist role that colleges play currently. The value there will make the 2 billion Facebook is trying to get seem like peanuts. :-)

Btw, have I told you about Schank’s Law already? I think not. Here it is in all it’s glory:

Schank’s Law

Because people understand by finding in their memories the closest possible match to what they are hearing and use that match as the basis of comprehension, any new idea will be treated as a variant of something the listener has already thought of or heard. Agreement with a new idea means a listener has already had a similar thought and well appreciates that the speaker has recognized his idea. Disagreement means the opposite. Really new ideas are incomprehensible. The good news is that for some people, failure to comprehend is the beginning of understanding. For most, of course, it is the beginning of dismissal.

by Roger Schank, as it appeared in The World Question Center 2004

What would you do if you realized you had become a 21 y.o. petulant, cranky, old fart1?

Golly! That’d be some positively nasty tidings2 —or not. Would you rather not know? There’s nothing left now but pick up the pieces, apologize, and start over.

Here’s an excellent formist intro to international auxiliary languagesWP written by Eward SapirWP himself (one of the most influential American linguists of the past century) in 1925:

There are many, many highlights to be made. Here’s four

  1. The “difficult and subjective concept” of the richness of a language, the “richness of connotations” (that phrase alone was worth the price of admission). This was precisely what I was getting at in my badly-received post On the Language of this Blog.
  2. “It is true that English is not as complex in its formal structure as is German or Latin, but this does not dispose of the matter. The fact that a beginner in English has not many paradigms to learn gives him a feeling of absence of difficulty, but he soon learns to his cost that this is only a feeling, that in sober fact the very absence of explicit guide-posts to structure leads him into all sorts of quandaries.. The simplicity of English in its formal aspect is.. really a pseudo-simplicity or a masked complexity.
  3. His dazzling insight that the problem of finding an adequate international auxiliary language is really the problem of how best to “symbolize thought.” Wow. Just wow.
  4. ”A common allegiance to a form of expression that is identified with no single national unit is likely to prove one of the most potent symbols of the freedom of the human spirit that the world has yet known.” ‘Nuff said.
* * *

Y’know, just between you and me, when the time is ripe—that is, in around 10 years—I would love to plunge myself in language: I would love to speak (and think in) Esperanto, Japanese, German, French, Mandarin, Portuguese, Italian, Catalan, Russian, Hebrew, Sweddish, Arab, Hindi… —Oh! Were languages not the harsh mistresses that they are! I’d love to work (and solve!) the problem of automatic machine translation (which, according to Kurzweil, will be the last task left for AI to emulate, the crucial last stepping stone to consciousness). I’d love to read both Ulysses and Finnegan’s Wake. I’d love to construct all sorts of constructed and auxiliary languages. I’d love to write in Esperanto and join la movado. I’d love to become a Wiktionary super-freak. I’d love to write language textbooks. I’d love to create a compiler and write programming languages. I’d love (in a most masochistic kind of way) to be a professional translator and translate a novel. I’d love to study some serious linguistics. I’d love to do advanced algebra. I’d love to become a Lisp super-freak or, quite oppositely, think in assembly code. I’d love to understand Goedel’s incompleteness theorem. I’d love to work in the semantic web. I’d love to create software to help one read and absorb written information (we have software to write, word processors, so why don’t we have software to read?).

Oh well, please excuse the future lapse.

I used to laugh at the elaborate calculations and stratospheric numbers you always find when reading papers about the limits of computation —as in, say, “Just how much computations per second might the entire universe theoretically support?”. It was something more than my incredulity (it involves too much hand-waving at times), it was simply indifference. So what if the universe could theoretically handle one zillion jillions to the gazillion cps? We might as well ponder how many angels might fit on the head of a pin…

I read Ray Kurzweil answer 3 weeks ago and it hasn’t stopped resounding on my head ever since:

Because computation underlies the foundations of everything we care about, from the economy to human intellect and creativity, we might well wonder: are there ultimate limits to the capacity of matter and energy to perform computation? If so, what are these limits, and how long will it take to reach them?

Our human intelligence is based on computational processes that we are learning to understand. We will ultimately multiply our intellectual powers by applying and extending the methods of human intelligence using the vastly greater capacity of nonbiological computation. So to consider the ultimate limits of computation is really to ask: what is the destiny of our civilization?

I must confess that I love Spanglish in a kitschy, campy, and yet honest kind of way.

It all started with Molotov and their ¿Dónde jugarán las niñas? album of my early adolescence. I loved their mongrel insults (”fuck you puto baboso!”) and their Voto Latino song:

I’ll kick your ass yo mismo
por supporting el racismo.
Blow your head
hasta la vista
por ser un vato racista.

Que sentirias si muere en tus brazos
a brother who got beaten up by macanazos?

Que sentirias si cae junto a ti
una hermana que canto una ”Rebel Melody”?

Pinta tu madre patria de colores
so you can’t tell the difference entre los others.

More recently, a song by Yolanda Perez (featuring “Don Cheto”), Estoy Enamorada, has brought it all back to me:

Don’t tell me por favor, que no lo puedes creer,
Si mis amigas tienen boyfriend yo tambien puedo tener.

Tu no me entiendes, Dad.
Yo no soy niña, Dad.
Yo voy a tener novio and I don’t care if you get mad.

Se que sigues saliendo con ese, stupid.
Ya se que se besaron no creas que no lo supi[!].

Yo lo unico que entiendo es que si lo veo por aqui, I kick his cholo ass.

Akwid, a recently famous group from Los Angeles, is a slightly different matter. Their music itself, for one thing, is something both truly different —mixing Mexican Pacific brass band with hip-hop— and truly good —the tuba “burping along like a nimble elephant.” But they don’t really speak Spanglish. It’s mostly just Spanish, but a different one from mine. One even more imbued with American influence.

They have a song called Pobre Compa in which the singer tells about a romantic triangle between him, his best friend and a girl. There’s a voice-over at the middle of the song in which the singer addresses the girl. One hears knocking, a door opening, and the following brief dialogue:

Akwid: Hola.
Girl: Hola.
Akwid: Se puede?
Girl: Pienso que si.
Akwid: Esta aqui?
Girl: No.

You can’t tell by the text, but the girl speaks her 5 words with a distinct accent that I love: crisp Spanish with an English cadence —which, btw, is completely different to gringo Spanish: broken Spanish with no cadence at all; an English tongue trying to mimic, unsuccessfully, Spanish sounds. And there was something else, beyond the accent, that I found interesting and appealing but couldn’t precisely pinpoint. I know now: it’s that “pienso que si”; a perfectly valid Spanish sentence, of course, but it feels somewhat unnatural to my Spanish sensibilities. “Pienso que si” mimics the English “I think so” where I would have more naturally said “creo que si” (“I believe so”).

It’s similar to the phrase “dulce para mi ojo” in their Taquito de Ojo song. That’s a quintessentially English phrase, “eye candy”, translated to Spanish inside a song with a quintessentially Spanish phrase as its title: “taquito de ojo” (“eye taco”). I like that.

Truth is, I love this blending whatever the language involved, I “delight in mélange.” Just to give an example, yesterday, via Diana, I found about a French Canadian group called K’maro and I was thrilled. They have true talent for Franglais, just look at this gem:

Welcome dans mon monde si tu party.
Welcome parmi nous si t’es naughty.

Or think about how “weekend” is now a French word. It’s much more natural to French cadence that the clunky “fin de semaine”.

Cargo Cult Yoga 2

In the South Seas there is a cargo cult of people. During the war they saw airplanes with lots of good materials, and they want the same thing to happen now. So they’ve arranged to make things like runways, to put fires along the sides of the runways, to make a wooden hut for a man to sit in, with two wooden pieces on his head to headphones and bars of bamboo sticking out like antennas—he’s the controller—and they wait for the airplanes to land. They’re doing everything right. The form is perfect. It looks exactly the way it looked before. But it doesn’t work. No airplanes land. So I call these things cargo cult science, because they follow all the apparent precepts and forms of scientific investigation, but they’re missing something essential, because the planes don’t land.

With the above text, Richard Feynman gave rise in 1974 to the concept of cargo cult science: pseudoscience in which only the trappings of science are cultivated. He makes a beautiful point through it and you should read that speech of his, it’s really good. In today’s yoga class, as my mind strayed during a ridiculously protracted baloney preaching, I chanced upon an interesting twist to it.

First, let me confess that I fell in love with yoga since my first class. I love the elegance, the gracefulness, the relaxation, the concentration, the self-awareness, the girl in green (a classmate), the austerity (only your body and a towel), the small daily improvements, the personal challenge of the perfect asana, the beauty and harmony of many postures, the sensuality of some, the ascetism of others, the breathing, the exhilaration that follows a class. I’m painfully stiff but I know I will get better. I want to. But this love only makes me loathe more the other, dark side of yoga: the mystical b.s., the astrology/chakra/aura/spirit/numerology/energy mumbo-jumbo.

Today I endured a particularly severe sermon (~40 min.) in which almost every esoteric subject save alien abductions was broached. When I decided I had had enough—and, believe me, I can be patient when listening to cranks—I stood up and prepared to leave. The teacher understood, laughed somewhat sarcastically, and wrapped the class with the closing posture. I thanked her for the class and left.

I knew that yoga carried such baloney baggage before I entered, of course, but I enrolled despite it. As much as the pundits (yogis) say they’re an inseparable whole, they aren’t, and I’m only interested in the exercise, the secular part. The funny thought that crossed my mind today was that, in a way, what I want is a cargo cult yoga.
