I don’t like notebooks either. I agree with a lot of @joelgrus ‘s reasons and have a few others of my own
Notebooks generally don’t play very friendly with source control tools such as git
Some information, such as TensorFlow Prints, gets invisibly printed in the backend rather than in the notebook
I can easily run the same bash script 8 times with 8 arguments on an 8 GPU machine. A notebook takes a lot of manual clicking around to do that
A notebook means I need to set up my environment correctly in two places rather than one (front end and back end)
Notebooks often degrade worse on flaky shuttle / airplane WiFi than ssh / screen do

One of the most anticipated GAN names now taken: paGAN. fxguide.com/featured/a-i-a…
Also, someone DMed me to warn me these results could be fake: reddit.com/r/MachineLearn…
To be clear, we don’t know if these allegations are true, just that they exist. And the company probably can’t comment publicly while the litigation is pending

I suspect that peer review *actually causes* rather than mitigates many of the “troubling trends” recently identified by @zacharylipton and Jacob Steinhardt: arxiv.org/abs/1807.03341
I frequently serve as an area chair and I manage a small research group, so overall I see a lot of reviews of both my group’s work and others’ work
It’s very common for reviewers to read empirical papers and complain that there is no “theory”. But they don’t ask for theory to address any specific question. I think they are just looking for an easy reason to reject—-they skim and don’t see scary equations.

A math trick I like a lot is the approach to taking derivatives using hyperreal numbers. Thread:
For this trick we introduce a new kind of number, called an infinitesimal hyperreal number. Imagine we have some number epsilon, such that epsilon > 0 but epsilon < x for all positive real numbers x. Imagine that we can use algebra to manipulate epsilon like any other variable.
Now we can compute derivatives just by using "plug-and-chug" algebra on the expression f'(x) = real_part(f(x+epsilon) - f(x)) / epsilon) where the "real_part" function just rounds off the infinitesimal part of some expression

@RANDCorporation Okay, this starts out with a major falsehood regarding the Battle of Ia Drang. Timothy R. Heath is the Rand Co. Senior International & *Defense* Researcher, & yet he gets things totally wrong about that battle - maybe because he only watched the movie or something.
@RANDCorporation "Using accurate artillery fire, close air support, and novel doctrines of air mobility, the disciplined, well-led American forces fought skillfully against a resolute and capable adversary that had been at war for decades. ... >
@RANDCorporation ... > Although U.S. forces eventually withdrew from the battlefield, they did so in good order and inflicted at least twice as many casualties as they incurred."

Going to do a little thread on what it’s like to be on the autistic spectrum. Will add to it from time to time, mostly myth debunking, stuff you might not know & how to help / interact with autistic people in your life. #ActuallyAutistic
Did you know that a lot of autistic people have problems processing sensory input? Even leaving the house can be totally overwhelming as we are less tolerant of bright lights, strong smells, loud noises (or multiple noise sources), textures, motion etc. #ActuallyAutistic
If you’re meeting an autistic friend, try to meet somewhere quiet & calm. If you can make the effort to travel closer to us, that helps greatly as long journeys can be really difficult. On top of the sensory issues, we can be very anxious about planning. #ActuallyAutistic

Agree w a lot in this thread, but this tweet is an odd take. I've not seen anyone suggest that there is no racism in the LP & that all claims of racism are smears. There's something v specific going on atm,which we all know even if many ppl won't admit it. The fact that there >
*is* a smear campaign against Corbyn/the left doesn't mean there is no AS or other prejudice in the LP, but the fact that these things exist in the party conversely also doesn't mean ppl don't use allegations of AS to smear Corbyn/the left. >
I've been accused of AS for advocating for Palestine & you know that's BS, as have numerous leftwing activists who are Jewish. Also, this needs to be said: there is a difference between ppl being subjected to abusive comments here in Britain (whether racist, misogynist etc) >
