Our 2023 ICASSP paper is now up on arXiv:

Dataset balancing can hurt model performance

https://t.co/TyawmB1OWK

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?

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.

[Channing Moore @ChannningMoore]

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.

Was out testing new film equipment. Drivers behaving brutally all over, but none so badly as the chaos at Chrystie & Delancy Streets.

Cranks love to complain about #bikenyc and say drivers don't break laws.

We know that's just not true.

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. https://t.co/0cNVLRpSn0

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

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?”

[Channing Moore @ChannningMoore]

@NYTcorrect @DougJBalloon

[Channing Moore @ChannningMoore]

Seriously, the map in this article replaces Tunisia with a new arm of the Mediterranean. What map tool even allows you to do that?

@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.

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.
