🧵 Tonight's SFI Community Lecture by 2x Miller Scholar @Andrea_Wulf begins in just a few minutes!

Follow this thread for the streaming link and highlights from the talk. (Sorry, but this recording will not be available to view afterward...)
Talk starts now with an intro by SFI Prof @C4_Computation:


Q - Flack: "Some of you might wonder how a talk on Humboldt connects to #ComplexityScience."

A - Humboldt: "Knowledge of the chain of connection....the perception of these relations."
Who was #AlexanderVonHumboldt?

"A man who was so restless he said he was chased by 10,000 pigs... He spent his entire inheritance on a five-year voyage of South America. They called him 'The Shakespeare of the Sciences.'"
- @andrea_wulf
"#ThomasJefferson called him 'one of the greatest ornaments of our age.' #Napoleon was jealous of him. #JohnMuir's ideas were heavily influenced by his work. #Goethe said spending a few days with him was like several years. The @NYTimes dedicated an entire page to his birthday."
"He was the father of #infographics and the forgotten father of #environmentalism. I also like to say he was the father of #ComplexityScience."

"When you write a book about an explorer, the great thing is that you have to travel the world to follow in their footsteps."
"They almost starved to death. They suffered high fevers. They encountered jaguars & crocodiles. They collected 1000s & 1000s of plants. But he was not just interested in nature. He was also interested in the Indigenous people & said they were the best geographers he'd ever met."
"He described what the forest actually does for an ecosystem, and wrote about humankind's ability to destroy nature. He said in 1801, 'There might be a time when humankind could travel to other planets...and -[will] leave those distant planets as barren and ravaged as Earth.'"
Climbing #Chimborazo, "He noted everything with scientific instruments every few hundred yards."

"They were at 19,340 ft, about 1000 feet before the peak...and had to stop. But they achieved something remarkable: no one else had been this high anywhere else in the world."
"Using Humoldt's data researchers in 2012 noted that the plants he had recorded at different altitudes had retreated up the slopes [in response to #ClimateChange]."

"'The study of #nature,' he wrote, 'does not exist in the sterile accumulation of isolated facts.'"
"He left #ThomasJefferson 19 hand-written pages...and collected locked trunks with 1000s of bird specimens."
"He jumped from one another equally]. Everything...he said, was linked together, forming one hyper-indiviual."

- @andrea_wulf
"#CharlesDarwin read his #Humboldt books with pencil in hand. Humboldt's descriptions of South America made #Darwin *want* to travel there."

"He said, 'I am at present eager to follow in his steps.' "[Humboldt] was described by a friend as a "pre-Darwinian Darwinist.'"

🧵 "The Smell of Inhibition. A Code in the Nose?"

ICYMI, this week's SFI Seminar by Fractal Faculty Stuart Firestein (@Columbia) on "what started out ass a very simple-seeming problem [re: #olfaction] and turned out to be very complicated":

"Everything we know about the world comes through these little holes in our head and the skin covering our body, processed through tissue specialized to interpret it."

"The thing to notice about [sight and hearing] is that they're [processing] fairly low-dimensional stimuli."
"Even a simple smell is composed of a VARIETY of molecules, and these are high-dimensional from a chemical point of view. And it's also a somewhat discontinuous stimulus. How do we get from this bunch of molecules to this unitary perception of something like a rose?"

🧵 "#Possibility Architectures: Exploring Human #Communication with Generative #AI"

Today's SFI Seminar with ExFac Simon DeDeo @LaboratoryMinds (@CarnegieMellon), streaming now:
"A key feature of this is talk is that we make sense of what each other are saying IN PART by what they say, but ALSO by what we expect of them."
"Language transmits info against a background of expectations – syntactic, semantic, and this larger cultural spectrum. It's not just the choices of make but [how] we set ourselves up to make later choices."

"I think what really drives [the popularity of the #multiverse in #scifi] is regret... There's a line in @allatoncemovie where #MichelleYeoh is told she's the worst version of herself."

"I don't think we should resist melting brains. I think we should just bite the bullet."
"When you measure the spin of an electron, or the position...what happened to all of the other things you could have seen? Everett's idea is that they're all real. They all become real in that measurement."

"At the level of the equations there is zero ambiguity, but the metaphors break down. The two universes it splits into aren't as big as the original universe. The thickness of the two new universes adds up to the thickness of the original universe."

"Compositionality in Vector Space Models of Meaning"

Today's SFI Seminar by @marthaflinders, streaming:


Follow this 🧵 for highlights!
"Scientists gather here
Santa Fe Institute, oh so near
Inquiring minds seek truth"

#haiku about SFI c/o @marthaflinders & #ChatGPT

...but still, #AI fails at simple tasks:
"One way to represent the kind of #compositionality we want to do is with this kind of breakdown...eventually a kind of representation of a sentence. On the other hand, vector space models of #meaning or set-theoretical models put into a space have been very successful..."

"Humans are prone to giving machines ambiguous or mistaken instructions, and we want them to do what we mean, not what we say. To solve this problem we must find ways to align AI with human preferences, goals & values."
- @MelMitchell1 at @QuantaMagazine:

“All that is needed to assure catastrophe is a highly competent machine combined with humans who have an imperfect ability to specify human preferences completely and correctly.”

- Stuart Russell (@UCBerkeley) as quoted by @MelMitchell1 in her latest @QuantaMagazine article
"It’s a familiar trope in #ScienceFiction — humanity threatened by out-of-control machines who have misinterpreted human desires. Now a not-insubstantial segment of the #AI research community is concerned about this kind of scenario playing out in real life."

"Training Machines to Learn the Way Humans Do: an Alternative to #Backpropagation"

Today's SFI Seminar by Sanjukta Krishnagopal
(@UCBerkeley & @UCLA)

Starting now — follow this 🧵 for highlights:

"When we learn something new, we look for relationships with things we know already."

"I don't just forget Calculus because I learned something else."

"We automatically know what a 'cat-dog' would look like, if it were to exist."

"We learn by training on very few examples." Image
1, 2) "[#MachineLearning] is fundamentally different from the way humans learn things."

3) Re: #FeedForward #NeuralNetworks

"You choose some loss function...maybe I'm learning the wrong weights. So I define some goal and then I want to learn these weights, these thetas." ImageImageImage
