Theano: A Python framework for fast computation of mathematical expressions / arxiv

↑ mentions machine learning/ fast matrix algebra. is it used in physics?

AccidentalFourierTransform

@vzn en.wikipedia.org/wiki/Boltzmann_machine

unrelated but cool :-)

@AccidentalFourierTransform ah yeah, decades old model, classic, seems to connect ML and physics in deep ways...

its remarkable that some ML algorithms reduce to a sort of "energy shifting" or minimization/ optimization etc...

have you done any stuff with ML?

AccidentalFourierTransform

anyway, a friend of mine is doing her degree final project on machine learning, so I can tell you that it is used in physics a lot

but I haven't done anything so I dont know the details of it

@AccidentalFourierTransform cool, undergraduate? what degree? what kind of data?

@AccidentalFourierTransform ask her! :P

AccidentalFourierTransform

yes, undergraduate, physics

its about biophysics

3:24 PM

@AccidentalFourierTransform ML is really surging/ buzzing/ popping these days

crosscutting across (nearly all) scientific disciplines

3:57 PM

Is there something that can be done with path integrals that cannot be done with canonical quantisation?

is it really more general?

4:49 PM

Path integrals can be done for theories with no hamiltonian

I like how the paper in the comment I got for CSR is from 2 months ago

Good timing

@Obliv Hai

hallo

How's finals hanging?

5:06 PM

finished 'em

ezy pezy

how much school do u have left before u graduate

I already graduated HS

Our school year is Feb-Dec here

Just waiting to go to College now, probably heading to UCSD

weirdo

:(

nice i hope the transition goes smoothly

are you leaving any close friends at home? :o i imagine you won't be visiting that often?

I'm leaving everything :p

I don't have any family or anything in the US

5:11 PM

bring a keepsake at least :p

I only know 2 people in Cali :D

smuggle your pet with you and document your adventures

I don't have a pet :v

are you bringing your desktop?

Nope

5:12 PM

wai

My PC is a really old 2009 huge desktop

that wasn't all that great when I bought it

oh do u have a laptop tho

and that is on it's last minutes because of how many experiments I've done to it

Nope

I only have this desktop

I'll be getting a laptop when I move I think

i feel like a custom built pc and a tiny chrome book might be better idk tho

since u do more than just browse the internet i figure u might need a stronger pc

I need something that runs OSX

Sadly

And I don't game much so I don't care for power

I just need 4 cores so things compile faster

5:20 PM

i didn't know u couldn't get osx on a custom built desktop. i see what u mean though

You can build a hackintosh

on a desktop that is

but I don't want to go through the effort

I'm lazy

1 hour later…

6:23 PM

@DanielSank Amazon just called me for a fight

they updated the firware without me looking and broke my jailbreak

I'll crack this again even if it's the last thing I do on this god forsaken earth

6:45 PM

Jeez, dude.

@DanielSank They started it, all I wanted was to have a picture of the ocean as my screensaver

So confrontational.

:(

7:00 PM

Aww I'm just teasing you. You need it.

The teasing you mean? :p

7:11 PM

@ChrisWhite Should I go to work today?

Be my magic eight ball

mine broke

user54412

"Try again later"

Hmmm

Maybe it's a metaphor

I should try to go to work later

alright

user54412

actually I'm off to work myself

Great, now I feel guilty

Alright alright I'm getting my shoes on

user54412

The don't do shoes in SD :p

7:14 PM

No shoes in SD? Why?

Dan wore shoes when we met and he's in CA

No, wait, did he?

@DanielSank Did you wear shoes?

Sandals, brown sandals

user54412

To fully experience socal, you need sandals (for formal occasions), or better yet nothing

@ChrisWhite But I have a weird ass foot man

user54412

^ the possibilities for parsing that sentence...

Lol

What's the difference between Wightman and Osterwalder Schrader

Except for being Minkowski/Euclidian

7:27 PM

@BernardMeurer I wear sandals all the time.

Even when backpacking.

Q: Why is the electromagnetic spectrum called the electromagnetic spectrum?

I was just wondering about the etymology of the electromagnetic spectrum. We were studying electromagnets in class and I asked my science teacher why the electromagnetic spectrum was called the electromagnetic spectrum, she said i would find out when I was older but I really couldn't be bothered...

forces soft-question terminology

Off-topic?

I get so happy when I remember these details right, makes me feel young

@DanielSank I don't even own sandals

@BernardMeurer For the love of everything please use commas.

Or parentheses.

@DanielSank And kill the joke? Never!

I have a weird ((ass foot) man).
I have a ((weird ass) foot), man.

Very different meanings.

8:07 PM

@Qmechanic Er .. because it is a spectrum and results from electromagnetism? I think that if it has a place on Stack Exchange it probably belongs on History of Science and Mathematics or English Language & Usage.

Q: Can we have some MathJax functions pre-defined?

Can we have some MathJax functions pre-defined so that it is easier to write. For example: \ket{\psi} giving |\psi \rangle \braket{\psi_1}{\psi_2} giving \langle \psi_1 | \psi_2 \rangle \f{1}{2} giving \frac{1}{2} \l giving \left( \r giving \right) etc I know each one of these alone does n...

9:10 PM

@ACuriousMind You there?

@DanielSank Are you good with kinectics?

9:46 PM

@BernardMeurer You're better off just asking the question.

@DanielSank There's no question yet

A guy just passed me at the makerspace and asked if I was good at it

I said no

so I asked you guys

:p

@BernardMeurer what why?

@BernardMeurer That's a pretty vague question.
