Chomsky vs Norvig (with the help of O’Reilly)

Μέσω του Lieberman διάβασα πρόσφατα την κριτική στον Chomsky του Peter Norvig και συστήνω να την διαβάσετε και εσείς. Όχι επειδή είναι σωστή αλλά επειδή περιγράφει ένα σημαντικό πρόβλημα επιστημονικών αρχών. Και επειδή έχει πλάκα. Παραθέτω από το On Chomsky and the Two Cultures of Statistical Learning:

Chomsky is in complete agreement with Bill O’Reilly. (I recognize that the previous sentence would have an extremely low probability in a probabilistic model trained on a newspaper or TV corpus.)

Πάντως ομολογώ ότι παρ’ότι διασκεδαστική η σύγκριση με τον O’Reilly (αλλά και άλλα πράγματα στο άρθρο) με βρίσκουν να μην συμφωνώ. Το συμπέρασμα ότι το φαινόμενο της γλώσσας μπορεί να αναλυθεί μόνο στατιστικά είναι αυθαίρετο και ηττοπαθές. Συμφωνώ αρκετά με τις αντιρρήσεις του jmmcd στην αντίστοιχη συζήτηση στο Reddit.

Διασκεδαστικό επίσης βρίσκω ότι στο παρελθόν ο Chomsky έχει γίνει ο ίδιος αντικείμενο της ίδιας κριτικής που επιφυλλάσει αυτός στους “στατιστικολόγους”. Π.χ. από τον Shamuyan.

A Poem Beyond Belief

The Bad Astronomer

The Bad Astronomer

I just got to reblog this poem by The Bad Astronomer:

A Poem Beyond Belief by Phil Plait

A is Ad hominem, attacks quite insulting,
They may feel good but no good is resulting.

B is for Bible, they swear it’s all true,
But which version’s right? The Muslim’s, Mormon’s, or Jew’s?

C is Creation, 6000 years past;
But when looked at the evidence is always half-assed.

D is Debunker, it’s said with a jeer.
But we cannot debunk without bunk, that is clear.

E: EVP, hearing voices of dead,
but it’s really just patterns of sound you are fed.

F: The Face that’s on Mars is really a butte,
Is there on the obverse a giant patoot?

G is for Geller, a spoon he will bend,
Is it magic or powers, or more likely pretend?

H, Homeopathy, infinite dilution,
Perhaps better known as persistent delusion.

I, Ideomotor, the dowser’s director,
It fallaciously points on a randomized vector.

J is Junk science, it’s always reforming,
from alt med to New Age, and anti-global warming.

K is for Karma, you reap what you sow,
but if it’s not coincidence, then how would you know?

L’s Levitation, they claim that they float
but I think it’s just bouncing they’re trying to promote.

M: Mayans said: doom in Twenty Oh Twelve,
In 2013 those predictions we’ll shelve.

N is Nibiru, a planet of vapor,
It never shows up but it looks good on paper.

O: Oxygen water, marks can’t get their fill,
What they don’t understand is that they don’t have gills.

P: Faces in patterns is called Pareidolia,
In clouds it’s mundane but in pastry it’s holier?

Q is for Quacks, their science is lacking,
They’ll sell you snake oil with the government’s backing.

R: Repressed memories, bad things you’ve forgotten,
But it’s really the premise behind it that’s rotten.

S: Sylvia Browne, who randomly guesses,
That people believe her is why it depresses.

T’s for Trudeau, and the trash that he’s sellin’,
But credit card fraud? FTC: "He’s a felon."

U, Unidentified, the definition’s specific,
But it doesn’t stop cranks thinking they’re scientific.

V is Vaccines, which clear germs up quick,
But some folks don’t like them, they fight little pricks.

W’s for Woo-woo, Randi’s favorite word choice,
And who’ll argue with him? He gave us our voice!

X is for Xenu, scientologist’s Satan,
Give us all of your money, your engrams we’ll straighten.

Y is for Yeti, the Bigfoot, Sasquatch,
A whole lot of nonsense without a single hair swatch.

Z is for Zetans, those E.T. mind readers,
But they disappeared as they followed the Lieder.


Now you know your ABCs,
Don’t fall prey to fallacies.
