"1 Introduction
A locally testable code (LTC) is an #ErrorCorrectingCode that has a property-tester. The tester reads 𝑞 bits (randomly - but not necessarily uniformly chosen) from a given word, and rejects words with probability proportional to

>their distance from the code. The parameter 𝑞 is called the locality of the tester.

A random code has, with high probability, constant rate and distance, but locality that is proportional to the length. This is true even for random #LDPC codes [BHR05], and
>
>a priori the mere existence of codes with constant locality is not obvious. The first LTCs appear implicitly in works on #ProgramChecking [BLR90] and on #ProbabilisticallyCheckableProofs (PCPs) [BFL91, LFKN92, BFLS91, AS98, ALM+98].

Error, incertidumbre, precisión, tolerancia y exactitud. Términos relacionados con la calidad en una medida o la calidad de un dato espacial geográfico. Pero, se conoce con claridad qué significa cada término?. Ven conmigo 🤙
Comenzaremos con el término ERROR, es la diferencia entre el valor medido de una magnitud y el valor considerado como valor real o de referencia. El error no es conocido. #error
INCERTIDUMBRE: parámetro que nos indica la dispersión de los valores atribuidos a una magnitud. Este parámetro es conocido. #incertidumbre (Este es mi día a día cuando me pregunta el camarero qué quiero de beber... y ante la incertidumbre...al final acabo pidiendo agua)

El 25 de febrero de 1991, durante la Guerra del Golfo, una batería de misiles #Patriot estadounidenses no logró interceptar un misil #Scud. Murieron 28 soldados.

La causa: un error de 0.000000095 frente al gran error de la #guerra.

📺 latimes.com/archives/la-xp…

¿Qué ocurrió? ⬇️
Los #Patriot eran (son) misiles tierra–aire de largo alcance y carácter defensivo. Cuando el radar de la batería detectaba un ataque con misiles, los Patriot eran lanzados con el propósito de destruir la amenaza antes de que alcanzara su objetivo.

📺
El proceso era sencillo:

1⃣ El radar detectaba un objeto extraño.
2⃣ Sabiendo la velocidad de un #Scud, el sistema predecía su "posible" futura ubicación y comprobaba si el objeto había seguido dicha trayectoria.
3⃣ Si la amenaza se confirmaba, se lanzaban los #Patriot.

Today's Applied Complexity Symposium begins with a panel on Computation and Complex Economies, feat. Rob Axtell, Joshua Epstein, @C4COMPUTATION, Blake LeBaron, John Miller, & @MelMitchell1

(Follow this thread for live coverage all day...)

#complexsystems #economics
4 Principles of Collective #Computation:

1 Ground truth (objective reality)
2 Effective ground truth (what we agree on, whether or not it is accurate)
3 #Information can be collectively encoded in #networks
4 Outputs are a product of collective dynamics

@C4COMPUTATION right now
"I think #economics really needs to adopt a generative framework with agent-based models of cognitively plausible software people...[and] we don't choose to fear."

"If I were to write a textbook on #complexity, it would be structured like this..."
- SFI Pres David Krakauer starts off this morning at #CSSS19 #CSSS at @IAIASantaFe

#error #adaptation #universality #coarsegrained #math #theory
"If you talk about #intelligence and #stupidity, you talk about #communication and #policy. That is the natural place to start."

"If you've ever written a Lokta-Volterra #equation, you've drawn a perpetual motion machine. There's no #dissipation."

"Why #God is a bad #theory: it's not because it's not true; it's because it uses an infinite-dimensional process to explain low-dimensional phenomena."
