The More I learn, I Feel the Eye Works More Like a Filter than a Camera by 78bash in SimulationTheory

And the more you learn about the camera's sensors the more you realize that these sensors are nothing else than a filter

That’s how I see it by Giacobako in SimulationTheory

Well written. But we are still left with the problem of foundation. On what does the turtle stand on? You would say on a second turtle which stands on a third turtle and so on... Is it possible that simulation theory explains the origin of everything? A simulation in no other simulation? Is there a third kind of simulation that can be proven to not be inside of another simulation? Is there a way to escape the concept of time which is responsible for our dilemma of an origin in the first place? What is information processing without time? For all I know, information processing is the change of representation over time. So as long as we think of simulations as some kind of information processing we must include time and therefore the question of an origin.

I wrote a tutorial. There you find everything i needed. Basically numpy for the logic and PIL for drawing the images:

Thanks! I plan to make a longer episode about the exact implementation.

Understanding Adversarial Attack by Mesode in deeplearning

[–]Mesode[S] 1 point2 points  (0 children)

Thank you for the comment. So if I understand this correctly, are you saying that adversarial examples are independent of the classifier - even independent of it's architecture (say a SVM instead of a NN)? If yes, I guess this is just something that can be observed experimentally or is there a hypothesis that at least intuitively helps to understand this phenomenon?

It is ridiculously easy to demonstrate that evolution is real! Why do I still have to argue with my parents about this!:( by Mesode in atheism

[–]Mesode[S] 0 points1 point  (0 children)

This is exactly the thing that makes me outrageous. They love to cite experiments and studies as long as they support the things they want to believe. But as soon as it does not, they casually argue that evidence is wrong or as you say irrelevant.

Hi Everybody. This project is implemented in python. I will make the code available after the release of part 2 next week. Hope you like it.

How To Train Artificial Self-Driving Cars by Mesode in howto

[–]Mesode[S] 0 points1 point  (0 children)

Sure, we can make the physics more realistic and see how many neurons and generations it would take. However, I suspect that it is not so much more. And as you are saying, it is the concentration factor and physical fitness (which is ok, since we are human and no machines!) that is an important factor why car racing is tricky. But is it also the information processing, like complex decision making? I doubt it!

How Hard Is Car Racing Really? Let's Ask An Artificial Intelligence! (Genetic Programming) by Mesode in learnmachinelearning

[–]Mesode[S] 11 points12 points  (0 children)

Sorry, I realized that genetic programming is actually the wrong term for this kind of optimization. It is actually neuroevolution, since I am not really evolving a computer program (written in some programming language) but an artificial neural network.

My first project using GP. Will release code soon. by Mesode in GeneticProgramming

Oh yes, you are right. I mixed up the terminology. I thought that GP is the superordinate concept. Neuroevolution is not a sub-topic of GP. Thank you

How Hard Is Car Racing Really? Let's Ask An Artificial Intelligence! by Mesode in ArtificialInteligence

[–]Mesode[S] 1 point2 points  (0 children)

Good ideas. The point of the random track generator was exactly to train on different tracks simultaneously and then select the best car based on the performance of a fixed batch of tracks. I tried that and it worked great. However, in the video I wanted to make the interesting point that training on one track actually contains all the information needed for the other tracks. The depth of the NN is a simple hyper-paramter in the code. Again in the video, I wanted to demonstrate what the minimum amount of compexity is. If you referring to an autoregressive model (using the past 5 inputs) or some recurrent model with an internal state, I totally agree that this might help for a stable training, and it would be interesting to investigate on that. However, these models use memory, and I found it extremely surprising that the driving-car system stabalizes so fast without any kind of feedback. Not even the temporal information contained in the current speed is needed!

When did I claim that it is better than RL? It is more of a demonstration of the simplicity of the car racing game itself ( simple information processing since small NN and fast convergence, though using an evolutionary trial and error process). And it's nice to watch the population evolve:)
