@seohong_park @svlevine You may like to read up on some older literature by Duin & Pekalska, they did tonnes of work on the “dissimilarity representation”.

@predict_addict You’re very angry inside. I was highlighting a historically relevant tweet.

[Gavin Brown @profgavinbrown]

@OpenAI Not quite what the headline claims? GPT5.2 was a massive help in “simplifying expressions”? And a “scaffolded model” reasoned through the problem? So the scaffolding was contamination, seeding what researchers suspected the answer would be. It’s amazing, but not a true headline…

My son is learning to count.

He said “37, 38, 39, 40… Daddy, what comes after 40?”

I said “back pain and mortgages”

@MushtaqBilalPhD @nmatiaszczyk Very interesting that you didn’t check your sources.

[Gavin Brown @profgavinbrown]

@irfnali1 @mic_caprio Very kind of you to say so Ilan :-)

[Gavin Brown @profgavinbrown]

Very pleased to hit 2^7 citations for a work I consider the most satisfying (and long awaited) of my career. We solved the “ensemble diversity” question.

Look forward to seeing 2^8, 2^9….

@OmarRivasplata I think I can see my book on the left there….

@chrisoffner3d And to be clear also, those fields still are in “active research”, it’s just very different than before.

[Gavin Brown @profgavinbrown]

@chrisoffner3d I didn’t say it was done yet - the transition from academia to industry driving things took 15-20 years in each of those cases. It’s arguable the ML transition began ~2013, so we’re perhaps halfway. I know this from my colleagues in each of those fields, who lived through it.

@MushtaqBilalPhD @TheParableMan You know Cambridge is in the UK, right?

[Gavin Brown @profgavinbrown]

@MushtaqBilalPhD @TheParableMan Friendly guy….

[Gavin Brown @profgavinbrown]

@MushtaqBilalPhD @TheParableMan Well ok - it’s true in Denmark, but not true in the UK, or several other places that you put under the umbrella of Europe. It depends.

[Gavin Brown @profgavinbrown]

@MushtaqBilalPhD @TheParableMan That’s not true. It’s not uncommon to see someone in the UK starting a PhD after 3 years of just an undergraduate degree. Entirely depends on your grades and experience.

@pfau And the other one enabled was this: https://t.co/lmZguGjEOg

[Gavin Brown @profgavinbrown]

@pfau My favorite work that it enabled was this: https://t.co/OcG5iNrJOc

[Gavin Brown @profgavinbrown]

@pfau True in hindsight, but the bijection between ExpFams and Bregmans wasn’t known til Bannerjee (2006), and your paper made it clear to us that the central prediction is a left Bregman centroid, with all sorts of beautiful properties.
