Blue Brain Project and the 1.3 billion dollar

Now, it's  a while, that my love, the Blue Brain Project has got 1.3 billion dollars from the European Commission to finish it's work:

A very detailed simulation of human brain, a model that is hoped to work near to our brains. A new intelligent creature!!!

Markram, the head of the project, now seems has everything, money, supercomputers, good team, attention from the media and in short, what he needs. But for sure it needs extreme efforts to  get finished in the proposed  year, 10 years later.

I'm impationtly waiting to see their success whitin 10 years. Luck with you guys.

For more information about this project just check their official page that now  almost after being billioner changed to Human Brain Porject. ;)

Parametrized Complexity and Cognitive Science and Everything

Parametrized Computational Complexity, Who is this guy? a good guy or a bad guy,Let's see.

In Classic Computational Complexity, we say this algorithm is in NP, so kick it out. It's rubbish.

But Parametrized Computational Complexity says:

keep calm classic! The algorithm maybe is in NP but it's nature is p some damn parameters made it NP. So we can control these bad parameters(source of intractability), keeping them small and have a nice p algorithm.

The cognitive models I talked about in last post and I said they are considered rubbish, they may be acceptable by parametrized Complexity. The FPT(Fixed parameter Tractable) which hopefully I'll talk about in next posts is a tool for checking tractability in the view of parametrized Computational Complexity.

Hope to see you soon guys ;)

Computational Intractibility, The wet blanket!

Up to know, psychologists has introduced so many cognitive models, models that explain how our mind works.
BUT
What if our mind is just a Turing Machine, then are these models will work on our brain or maybe they are just some imaginations, and our brain never will be able to run them.

Oh, no, in this case all these models are just a rubbish?  Poor the ones who put a lot of effort on a model without checking its computational tractibiliy first.

Even if our brain is not a Turing machine and be superiour to it, still we need to check the tractibility of all models, because AI may need and can implement these models some day. And at least we know AI is on Turing Machines.

SO LET'S GO TOWARD CHECKING COMPUTATTIONAL TRACTIBILITY OF COGNITIVE MODELS, AND REJECT SOME FAMOUS COGNITIVE MODELS!!!

I'll post more about this issue, Have fun  ;)

Could our computers memories like our brains?

yesterday, I was thinking about swimming.  It lead me to think about my friend, Parvaneh(it means butterfly in Persian) who talked about swimming classes. suddenly, I thought she is professional in butterfly swimming.
After a while, I understood I made a mistake. Because of her name, I thought she knew butterfly swimming :D

I think we could have computers with a memory like ours. A fast efficient memory which may make mistakes.
It seems, this kind of model for saving information matches Memristor based hardwares(I donno much about Memristor).

 I searched the net to find if there is any similar computers, but no success yet.
I tried to write the relation between words which came to my mind (butterfly, swimming, my fried talk) in a flowchart like graph. but I don't know how true it is.

I always think by myself: as there should be a theory of everything in physics; it is not weird to have such a thing in neuroscience; hmmm, a set of rules or even one rule that can explain everything happens in our brains. It'll be fantastic.

Reconstructing brain vision

I have just read about the amazing work done by Berkeley neuroscienists: capturing visual activity in brain. the above video shows the result. It is wonderful. who can believe one day scientists could see what you see through your brain. more information is available here.

some tips about Batteries

Batteries that are thrown away produce most of the heavy metals. They can be harmful to humans and wildlife.

• Turn off the toys and games that use batteries when you are not playing with them. That makes the batteries last longer, and you won't need as many of them.

• Buy rechargeable batteries and a recharger.

• Check to see if your device has a "Battery Save" option. If so, you can turn this on to increase the life of your battery

• We should all take batteries to a toxic waste disposal area if it is possible.
