What does a neural network dream of?

“Was immer du hier siehst, verändere das Bild so, dass es stärker wird!” lautete die Anweisung der Google-Forscher an das neuronale Netzwerk. Und so fing das Netzwerk an, die Formen der Wolken auf dem Bild zu interpretieren: Was etwa ein bisschen nach Vogel aussah, wurde noch vogelähnlicher gemacht. So “malte” das künstliche Gehirn allerlei Fantasiewesen und Gebäude, die es zu erkennen glaubte. | Zeit.de – © Google Research

Google made multiple layers of neural networks analyze images and emphasize what they “think” they found in the pictures. The result is really impressive even though some of the pictures they were fed contained nothing but white noise to begin with. One could argue if that’s how AI dreams are made… well, and maybe even our own?

Athene’s Theory of Everything

Are you in the mood to think about how we see ourselves, why we believe in the things we believe and how we act upon those believes? Then you should consider watching this clip of ‘Athene’s Theory of Everything’, which is trying to explain and to unify all of our current philosophical questions with up-to-date scientific facts.

Don’t watch it, if you are stressed or not open minded for philosophical thoughts! You will be advised in the beginning of the clip, that the matter is complicated and multiple viewings might be required. But it is worth your attention and turns out to be very interesting, even when watching it for the the first time and when you might not be able to follow many of the details. Just play it again another day.

Among physics and biology, it even mentions the Mirror Neurons – a topic of the talk i have been putting up here in my previous post. I can’t stress enough that you should be advised to take some time to let all the ideas sink in, since it is quite condensed – especially if you are new to thinking about the ideas on how the world and we as human beings operate. However, it is presented in a very clear and calm way. In my opinion it is definitely something to take into consideration when discussing how ‘everything’ works…

The Empathic Civilization

Like I promised in my previous post, here comes another clip from RSA Animate, presenting a speed paint to a talk by Jeremy Rifkin called ‘The Empathic Civilization’. It is about the question of how we (and apparently also other mammals) feel empathy for something that can be observed happening to others. Like when we watch a movie, the same neurons fire in our brain processing what we see as if we would experience it ourselves. Scientists call this function in our brains the mirror neurons.

It is a remarkable discovery and he is talking about how it might have evolved from the bond that our ancestors in the cave had with their tribe (viewing other tribes as aliens), to religious groups believing to belong to each other up to the bond we feel towards the people of our same nation (and in many cases being hostile towards people of other countries). He then poses the very interesting question, if this evolution could extend over the whole planet to make us feel connected to one another as a whole ecosystem.

This is especially interesting to those who are working on ways how to convince people that we are not so different from one another. We should really stop treating people from other countries, religions and families as aliens. This is a very outdated concept in many parts of the world. The idea that, with our technology advances, it could be some day possible to overcome the differences between all of us and create what he calls the empathic civilization – where we act as a family of beings and not individuals. Think of the possibilities in sustainability and social equality that arise if we could just trigger these mirror neurons in each and every one of those who still live by the imaginary boundaries of nations, blood ties and religions.
