Our 2023 ICASSP paper is now up on arXiv: Dataset balancing can hurt model performance arxiv.org/abs/2307.00079 Dataset balancing works differently than you might assume: - can cause overfitting; - doesn’t improve performance on rare classes; - speeds up training convergence.

@starsandrobots Wald’s airplane, in the flesh?

No

This makes a mess of one of the city’s best bike routes on Christie Street. It’s no fun for the drivers on Christie, either.

This intersection has been a disaster for years. Drivers on Delaney block the box at commute hours and beyond. @ChrisMarteNYC this is your district. @LincolnRestler @crystalrhudson your constituents who bike into Manhattan have to navigate this every day.

To show the need for our checklist for ML research, we looked for a study to refute. It took just 1 or 2 hours to find that a model claimed to be 97% accurate is no better than random. My working assumption is that most ML-based science these days is junk. aisnakeoil.com/p/introducing-…

Life in Africa’s coup belt is rough, but things are even worse on the other side of the Sahara

Sea level rise is something else

It only took a couple of centuries, but @NYTimes confirms this morning that the exhortation of Cato the Elder has come to pass: Carthago deleta est.

@NYTcorrect @DougJBalloon H/t @RossKraemer who was staring at this map this morning saying, “wait, where’s Tunisia?”

@NYTcorrect @DougJBalloon

Seriously, the map in this article replaces Tunisia with a new arm of the Mediterranean. What map tool even allows you to do that? nytimes.com/2023/07/29/wor…

@HeerJeet I’m curious about how you’re using “WASP” here. Are you claiming that literal white Anglo-Saxon Protestants hold power in the US, or are you using it to mean something else? E.g., cultural hegemony, assets, or other things held by WASPs; or power held by whites generally.

10. The careers of Oppenheimer & Handler both suggest the limits of assimilation: it works up to a point but comes with costs & assimilated can always be discarded by the real powers that be (which remain in USA context WASPs).

Thanks to my co-authors, including @edfonseca_!

We used a partial version of the balancing scheme from the PANN and PSLA/AST papers. Full balancing (PANN, PSLA/AST) hurts mAP on a held-out set, but partial balancing gives a small boost over baseline:

@Julcuba I also see steel road plates in those photos. They are treacherous for cyclists on a good day because they provide very little traction. A line like that means cyclists will end up with both wheels on a plate and can easily end up falling. When they’re wet they’re a nightmare.

Police said 53-year-old Carlos Martinez was killed because he “failed to properly navigate the roadway...and fell to the ground” before getting run over by a truck on Bruckner Boulevard in the Bronx —but new video questions the simplicity of that statement nyc.streetsblog.org/2022/05/27/cyc…

@starsandrobots Where does this leave the nuclear-powered-aircraft people?

Nuclear energy people and electric aircraft people should naturally be friends.

@EricaNemser @SB_Corrections My first thought when they wouldn’t give me COIR was, “have these people ever bought a doormat?”

@SB_Corrections Understood. For those who would enjoy an ode to coir, there is this nytimes.com/2019/10/07/rea…

@Hilary_Barth @PaulMinda1 There are worse things to study.

@PaulMinda1 Avian cognition! Definitely. And it might become a reality: while our child lab can’t do in-person work, might as well go out and watch some crows?
