ml is not a hard coded set of if-else pairs. it's a glorified fit with a lot of parameters.

More accurately:

>matrix multiplication

[–] Flower@sh.itjust.works 12 points 2 days ago

Had one guy asking if AI is conscious. I said the whole thing is actually one very big excel sheet, so does he think that excel can be conscious? Anyway, I think the guy is now in a relationship with office.

[–] Gladaed@feddit.org 28 points 2 days ago (1 children)

Max(input*weights, 0) is an if in a sense, I guess.

[–] mrchampion@lemmy.world 4 points 2 days ago (1 children)

Good old ReLU. I've heard that CNN's perform better when using ReLU as the activation func, and that's probably why; ReLU acts as a filter on the image's features.

[–] Gladaed@feddit.org 9 points 2 days ago

Nah. Without a nonlinearity you just get a linear combination of inputs instead of the output of a deep neural network. ReLU or Ramp is just the simplest possible non linearity. Using a simple function can enable using deeper networks yielding even better performance.

It's actually somewhat of a headache, numerically. Works well enough tho.

[–] Epzillon@lemmy.world 14 points 2 days ago (2 children)

Yes, it is inherently incorrect, I just think that increases the fun factor. It reminds me of that guy who wrote a prime-checker for his thesis and it was just a massive list of if-statement

[–] weps@lemmy.world 33 points 2 days ago

98% accurate prime checker, super fast

isPrime() return False;

[–] Rhaedas@fedia.io 5 points 2 days ago (1 children)

A transistor is on or off. It's all if-then.

[–] Viceversa@lemmy.world 4 points 2 days ago* (last edited 2 days ago) (1 children)

No, it's more elemental: it's all ands , ors and nots

[–] nop@lemmy.world 4 points 2 days ago

Boolean math let's you convert it all to nand gates. For ease of manufacturing this is what is done.

[–] glibg10b@lemmy.zip 10 points 2 days ago (2 children)

Matrix multiplication, activation functions and softmax. Also some matrix addition sometimes. That's literally it

[–] agamemnonymous@sh.itjust.works 1 points 1 day ago* (last edited 1 day ago)

I mean yeah, the mechanism itself is straightforward, but isn't a big thing that we don't really know what it chooses for its... basis vectors? Something like that, I don't do programming and I'm out of practice with matrices

[–] Viceversa@lemmy.world 5 points 2 days ago

Everything is quantum field fluctuations.
That's literally it.

The human brain is far too complex to understand

looks inside

it's just meat

[–] NeilNuggetstrong@lemmy.world 59 points 2 days ago (2 children)

The brain isn't meat, it's fat, and is known to turn to soap under the right conditions. Which coincidentally also explains the soapy tiddy memes.

[–] some_kind_of_guy@lemmy.world 40 points 2 days ago

🤚sapient

🫰saponified

[–] panda_abyss@lemmy.ca 3 points 1 day ago

The brain can turn into soap? Did it still work after? Can soap think?

[–] JoeBigelow@lemmy.ca 11 points 2 days ago

Singing meat!?

[–] fubarx@lemmy.world 71 points 2 days ago (4 children)

That was old AI.

New AI uses a complex, multi-layer sequence of Magic 8-balls.

"Mirror mirror on the wall please fix my awful code, make no mistakes"

[–] marcos@lemmy.world 24 points 2 days ago* (last edited 2 days ago) (1 children)

That's a common misconception. It is a complex multi-layer sequence of heavily biased Magic 8-balls.

[–] 666dollarfootlong@lemmy.world 13 points 2 days ago

With a post-it note saying "be polite, don't hallucinate"

[–] LodeMike@lemmy.today 4 points 1 day ago

I wouldn't be surprised if some stuff (as in architecture) was solved by querying a different model to solve a problem

[–] Epzillon@lemmy.world 1 points 1 day ago

I would be heavily more inclined to use LLMs (and also probably use it in a more correct manner) if it came in the physical form of a magic 8-ball that I would violently shake to get the answer.

[–] Agent641@lemmy.world 65 points 2 days ago (1 children)

You don't have to be an AI developer to not understand your code. I not understand my code every day.

[–] TrickDacy@lemmy.world 2 points 2 days ago
[–] red_tomato@lemmy.world 55 points 2 days ago (2 children)

It’s just y = k*x + m a few trillion times.

[–] Mirodir@discuss.tchncs.de 2 points 1 day ago

You're forgetting the activation function to break linearity, otherwise you can only model linear trends. Many activation functions have "if" hidden in them (e.g. ReLU with the "max").

[–] cathfish@lemmy.world 9 points 2 days ago

Yes it's not even for loop and if. Just multiplication and addition.

[–] Big_Boss_77@fedinsfw.app 26 points 2 days ago* (last edited 2 days ago) (2 children)

Have you ever tried to follow five hundred nested for loop and if statements? Shit is nuts...

[–] thebestaquaman@lemmy.world 15 points 2 days ago (1 children)

Oh, just wait till you hit that sweet sweet python "Everything can have an else block"

if some_shit:
    try: 
        for stuff in thing:
             if stuff is bad:
                  raise ShitHitTheFanError
             # Massive block comment
             do = the_thing()
             if do is good:
                  break
        else:
            do = the_other_thing()
            if not a_thing:
                help_me() # May raise NoHelpFoundError
    except ShitHitTheFanError:
         my_life = recover()
         if my_life is bad:
             for fuck in my_life:
                  try:
                      fix(fuck)
                  except NoHelpFoundError:
                      break
             else:
                  fuck_this_shit()
    else:
         wat_is_going_on()
else:
    theres_another_one("?")

I'm a network engineer lol python is all I know... and yup, the else is a curve ball from hell

But this is absolutely fucking hilarious

[–] GamingChairModel@lemmy.world 4 points 1 day ago

Conway's Game of Life is Turing Complete and that fact has been fucking with my mind for like 25 years.

[–] luokaton@lemmy.zip 32 points 2 days ago

come on, it’s not that simple!

there’s also linear algebra

[–] nroth@lemmy.world 1 points 1 day ago

Indeed! See: induction circuits

[–] anon_8675309@lemmy.world 10 points 2 days ago (2 children)

If statements are some of the largest sources of bugs in software.

[–] Epzillon@lemmy.world 2 points 1 day ago (1 children)

I mean, without if statements and loops theres no logic? It would only be flat code, so i mean... Yeah?

[–] renormalizer@feddit.org 1 points 1 day ago

All you need for Turing completeness is finite precision floating-point operations and an infinite loop.

[–] lugal@sopuli.xyz 9 points 1 day ago

If this is true then everything is fine.

Edit: Damn, I'm part of the problem, right?

[–] khanh@lemmy.zip 1 points 2 days ago

repeat that for like one hundred billion times and now THAT's innovation
