So, we all know that the brain is not like a computer because it can find new algorithms without those algorithms being hardwired into it, but then how does the brain determine answers to new algorithms without some stochastic method?

>> No.5578207

>So, we all know that the brain is not like a computer
It is.

>because it can find new algorithms without those algorithms being hardwired into it
Because it has an algorithm for finding algorithms.

That would require infinite processing power.

Precisely my point.

I'm sure that C compilers would be very upset to hear that you don't think that they exist.

Do CS majors really believe that the brain is like a computer? Why don't you take some neuroscience courses before responding on a topic you don't even remotely understand?

Or is it just butthurt transhumanists mad that they won't be able to upload their brain?

I thought you were actually implying that it had infinite processing power. Never mind.

The brain is constantly receiving and processing external input. This stream of data is often how the brain overcomes the limitations of a static computer system.

Having trouble with a math problem? Read a book, ask your friend, turn the piece of paper upside down. Computers can't really do this at the moment.

The best way to think of your brain, isn't a processor, or an algorithm. Instead you have to look at as though every single neuron in your brain representing a table in an utterly massive database.

its in equilibrium you fucking retards! the plane wont get any lift and thus not do shit.
-also the friction between the tredmill and the wheels will produce so much friction that both the wheels and the tredmill will melt!

What the duck does this have to do with Godel? You have no idea what you're talking about.

>That would require infinite processing power.
The brain's resources are limited. That's why we can't solve every problem. Cool story. Tell me something I didn't know.

I have a B.S. in Neuroscience from U of Michigan, and am getting a second degree in CS; your brain is definitely a computer.

I live in Ann Arbor, and I can confirm this poster is not from UofM. No one from here will ever call it "U of Michigan"

Define computer then. Neural networks do not operate with "algorithms" and all the other bullshit posted in this thread.

>> No.5578245

It's an analog computer at best and doesn't even fit that except by the most liberal definitions of trans-humanists desperate for computational theory to allow them immortality.

Needless to say, I do not believe you.

>> No.5578249

>>5578244
O_o, seriously bro, do you even CS? An algorithm is simply a sequence of calculations or manipulations that produces a result in finite time. Every one of your neurons performs said action on the inputs it receives (in a manner of speaking).

>>5578242
No current student would, you're right. I graduated a few years ago, and during my travels it seems that when you're speaking to people from all across the US, "U of M" means something different to everyone.

>> No.5578260

>>5578245
Actually its a hybrid analog/digital computer, a computer need not use binary nor any of the traditional things we consider properties of a "computer". Also, you scoff at the idea that the brain is a computer, but if it isn't, how are we cognizant? What does the brain do that allows us to measure and perceive both consciously and unconsciously?

I don't claim to have any idea, I would certainly just assume it's something we haven't discovered yet, considering how little we known about the brain of even lower creatures, before I would say that it's a soul or something metaphysical, however.

>> No.5578277

>>5578269
But we have discovered it, you can literally make little circuits out of neurons in a petri dish if you want. Your brain is 100%, without any doubt, a very complex, highly self modifying, embarrassingly parallel, complex organic super computer. Sure we can't discern the exact calculations they're making on a neuronal level yet, but that's only because the technology isn't quite there, but we know exactly how neurons work, and therefore how they create circuits and perform calculations.

Sorry bro. That's just wrong.

>> No.5578310

theres already technology that can read brain waves and see black and white shapes almost perfectly recreated by reading the brain as it computes the images your eyes are looking.
