Imagine the neural network (NN) as a black box inside a space with internal functions, inputs, and outputs. All its outputs are dependent on the inputs with a unique idea: auto-training.

Inside the software, every possible function points in the direction of the existence of the network. As for its intelligence, it's undeterminable, an open question. But the human brain, whose intelligence is very high, can be investigated for patterns.

got some more advanced reading material senpai?
some kind of fundamentals in designing these, or more complex examples with the actual models attached/illustrated?

I'm always stuck with just piling in more and more nodes, but I understand a big part here is connecting multiple simple NNs together, but nobody online seems to care about actually implementing these, instead they rant about how cool they are.

That's really cool. I wish my library had a 3d printer, or they were economical enought that I could justify purchasing one. The biggest obstacle to me experimenting with embedded hardware is the fact that I'd have no case for what I design / build. 3d printing seems to be more niche than 3d printing enthusiasts make it out to be though.

Commercial development of free software is no longer unusual; such free commercial software is very important.

But regardless of how you got your copies, you always have the freedom to copy and change the software, even to sell copies.

That's simple: it means a design that permits users to use the design (i.e., fabricate hardware from it) and to copy and redistribute it, with or without changes. The design must provide the same four freedoms that define free software.

the people in this thread are crazy. $599 is a good price for a smartphone of this caliber. I'm going to save for one and make it totally custom.

anyway, does anyone know how I can preorder from these guys without divulging information? like if I wanted to secretly mail it to (i should go to /paranoid/ shouldnt i?) an undisclosed address and put fake names and just pick up the package locally?

If you are forced to use Windows for work like me, you should look at Aquasnap. Closest thing I've found to a fully functional tiling window manager for Windows 7 but I am open to suggestions if someone has found something better/free.

Shilling for it because I've been using it for a while on my work machine, but be warned that it is not libre and also costs some dosh for mulit-monitor support.

Welcome to Chaos General!

This thread is to discuss chaos theory, dynamical systems, many-body systems, nonlinear dynamics, fractals… You name it!

Untill recently, classical mechanics was thought to be the realm of determinism, opposed to quantum mechanics where the only certainty is uncertainty. Chaos theory shows us that we don't have to travel to the microscopic to find rich, unpredictable behaviour.

Prerequisites for studying chaos theory:
Since chaos theory is a branch of dynamical systems, a decent maths preparation is necessary. Calculus and also some abstract algebra are needed to undertake the study of chaotic dynamics.
A basic course on ODE and mathematical physics is also necessary. A classic would be Arnol'd's book.
Some knowledge in measure theory helps, there are heaps of different resources and approaches to it, for example Folland's book, although it is quite advanced.
Files and more resources in the next posts!

The world of dynamical systems is large, and chaos is a part of it. My personal interest in chaos theory is at a crossroad between chaos and what is not chaos, namely, integrability. This area is called KAM theory (Kolmogorov-Arnol'd-Moser). It's a fascinating branch of mathematical physics that shows what is lost and what is not lost after perturbations of integrable systems. A lot of natural systems are in a balance between chaos and order, so this theory gives us deep insight on such phenomena. Also, it has the best fractals!
https://en.wikipedia.org/wiki/Edge_of_chaos

There is an article on Lainzine 4 about an elementary chaotic system, and there will be followups in the next Lainzines. What do you think of it?

There is a good discussion to be had on point of philosophical implications. We know from history that all advancements in science have followed with philosophical systems that act as sort of meta-proof or build on methodology of that particular science - i.e. Hobbs builds hes political philosophy on newtonian mechanics which can be seen from his fundamental principle of inertia which he adopted and applied it to social science. Who would have thought that we would have political philosophy (that is considered basis for modern liberal society) founded on new laws discovered in physics?

In quantum physics we have physicist fight over philosophical systems that quantum theory implicates. Bohr and Heisenberg have idealist philosophical outlook rejecting positivist, deterministic explanation of nature, for them everything is phenomena going that far that they claim that object of observation doesn't exist until we observe it.

Most interesting in my opinion dialectical materialism. Marx builds it on Hegels dialectics which reject concepts of isolated causality in classical mechanics. Bohm expresses similar criticism: Thus, there is no real case known of a set of perfect one-to-one causal relationships that could in principle make possible predictions of unlimited precision, without the need to take into account qualitatively new sets of causal factors existing outside the system of interest or at other levels.

Problems of isolated cause and effect and determinism that challenged classical mechanics in its contradiction to quantum mechanics give legitimate consideration in Hegels philosophical system. Therefor there are plenty of marxist philosophers that make effort to merge chaos theory with dialectical materialism. I guess that could be said for classical hegelians.

i.e. these are some accounts on hegel and chaos theory

It is easy to identify cause and effect in isolated cases, as when one hits a ball with a bat. But in a wider sense, the notion of causality becomes far more complicated. Individual causes and effects become lost in a vast ocean of interaction, where cause becomes transformed into effect and vice versa. Just try tracing back even the simplest event to its "ultimate causes" and you will see that eternity will not be long enough to do it.

Thank you for contributing, I thought this thread would die of neglect.

What you say is very interesting. Indeed, certain advances in maths, for example category theory, have had great rebound on philosophy, in lots of different areas (logic, but also ontology!). But I'd develop this on a more maths-specific thread.

I would like to stress on the fact that chaos is not only quantum. Actually, since quantum physics has a hard foundations problem, more mathematically-flavored accounts of chaos are realized in the realm of classical mechanics.

But the determinism hard coded in classical mechanics is nothing to be against. In fact, chaotic systems are, in a certain sense, ultradeterministic.

What I mean with this is that you may chose a property you want a solution to realize, and a chaotic system always has at least one such solution. So the dynamics in the chaotic realm is so rich it is akin to random processes: you may flip a coin and decide from the outcome that some solution should have some property, and the chaotic system will have such solution. This is a twisted version of determinism, where the possibilities, whose evolution along their "worldlines" is perfectly causal, are so many that the result is non-causal, entropic.

To expand, there always is a sort of "microdeterminism" in classical systems: the dynamics of one single point are totally determined by its equations of motion, well in contrast to the equations that govern quantum mechanics, which determine probability distributions.
So determinism is still there, but to really experience it, you must restrict yourself to an insignificant part of the system. Globally, or even locally (in the topology sense), determinism is not true: the evolution of a set of points is not guaranteed to mimic the evolution of a single point, and this is true also for non-chaotic systems (Gromov's non-squeezing theorem)!
For example we may take the single points of the set very close (small initial uncertainty), but the dynamics can separate them exponentially in time. As a result, the small initial uncertainty is propagated, deterninistically, to an enormous uncertainty at a further time.

I love pure mathematics, but many often discourage going into it because of its lack of job opportunities, and that people should study computer science or accounting or medicine instead.

Here's a list of jobs for pure mathematicians (note that some of them require programming/computer science knowledge as well):
>professor or teacher
>research analyst/actuary
>cryptography/security
>computer graphics
>artificial intelligence
>software developer
>insurance

Some more unconventional things:
>law
>music composition
>knitwear

Feel free to add or dispute anything here.

Hello, Lains! What wearable tech do you use throughout your daily life? Some might argue that wearable tech is a minor form of augmentation. Everything from smartwatches to the Sensebridge Northpaw are welcome here.

I own a model of the original Pebble smartwatch, with a watchband I paracorded myself. The attached picture is a random one I found on the internet, however (mine is black and olive-green). I created a watchface that read "FUCK YOU" in large, block letters and told me the time/date/weather in a small status bar beneath. I also set it up to vibrate at set intervals of five/ten/fifteen minutes in order to better tune my sense of passing time.

The Northpaw is an anklet that vibrates in relation to which way the wearer is facing.

>"A North Paw is an anklet that tells the wearer which way is North. The anklet holds eight cellphone vibrator motors around your ankle. A control unit senses magnetic north and turns on and off the motors. At any given time only one motor is on and this motor is the closest to North. The skin senses the vibration, and the wearer’s brain learns to associate the vibration with direction, giving the wearer an intuitive sense of which way is North. "

Never found the use of a wearable to very convenient. With my phone on me at all times, to have a other device just to control and view the basics seems very tedious. I could imagine getting one once technology allows them to be act on its own, without a phone only needed to link when it comes to texting, phone calls, etc.

No apps, no bluetooth, no online accounts or step tracking or any nonsense.

They need galvanized and paint. Something that robots do to millions of cars every year on production lines around the world. Something the robots could do to prefab container structures and cladding prior to assembly, if they were churned out on a production line.

Wood rots. Brick and mortar needs re-pointed. Everything needs maintenance. The point is, cheap affordable housing does not come from currently existing materials and currently existing building practices and techniques.

Prefabricated houses have existed in the UK since the early 1900s when we needed to re-home large parts of the nation after the slum clearances and after the Blitz and other bombing raids during the second world war. Same for many European cities.

Today, prefab houses are a similar price to traditionally built homes because of low production numbers and bespoke high end finishes. When churned out in bulk and to one standard, such as for student or social housing, they're much much cheaper to produce, maintain and replace than any brick and mortar, permanent structure. It's already been proven in Europe.

If you can put together a container home production line to address the housing crisis, it will be the cheapest means of house construction we've seen since building with wattle and daub and as revolutionary as when Ford moved automotive production from bespoke coach built, to the production line.
