@cricket_Stats05 @grok He has been to a rave with no cam rule.

[Yannick Kälber @YannickKae]

@RiotIQ Reading some actually reasonable research on that topic reminds me of the completely made-up bullshit that this Taleb cuck, Sean McClure, wrote about it on Medium.

[Yannick Kälber @YannickKae]

@pedma7 No, the 11 Oscars for the third movie were just as random as the Oscar for Michael B. Jordan this year.

Very overrated triology.

[Yannick Kälber @YannickKae]

@justalexoki Do it. Regardless of whether you are vegan or not, if you leave all the culture war bullshit behind & act like a grown-up for once, you have to admit it’s actually a good thing to be.

@alisha_hg Tracking for some time & regaining a feeling for what you actually eat is essential.

[Yannick Kälber @YannickKae]

@alisha_hg True. Also important for people who start doing sports to lose weight, which often leads to even more weight gain as they become hungrier & think they can be less careful with what they eat cause they're exercising. Many such cases.

Did a paragliding taster course over the weekend and it was a blast.
I think I’m going to go for a license.

@fchollet @hughesanalytics This chart won't die because it's from JPM, people perceive it as a top-tier institution, and people have authority bias.

Even those who should know better will turn off their brains as soon as they see JPM.

@volatilitysmile @W98AB Digga Berlin… gottlos

[Yannick Kälber @YannickKae]

@W98AB @volatilitysmile Germans aren't just known for cars & dark history from a century ago, but also for techno & fetish.

@RealEmirHan Bale was the perfect cast for Bruce Wayne. He had the charisma of old-money, while still being masculine enough to embody Batman. Affleck on the other hand lacks this elegance. He feels more rugged.

[Yannick Kälber @YannickKae]

@trikcode There is a professor, Roland Tichy’s brother at KIT, who is famous for keeping everything in German (e.g. Brandmauer instead of fire wall), which is a bit bizarre. „Keeping it German“ seems to be a Tichy family trait…

[Yannick Kälber @YannickKae]

@trikcode Most German universities teach at least their master's programs entirely in English. Since the majority of computer science literature & online content is in English anyway, Germans also learn & code in English.

[Yannick Kälber @YannickKae]

I kind of feel sorry for Jürgen Schmidhuber and his crusade to point out under every LinkedIn post that his academic work wasn't referenced and that he already had Yann LeCun's idea back in 2014.

[Yannick Kälber @YannickKae]

@systvest @W98AB Love it. Er auch

[Yannick Kälber @YannickKae]

@W98AB recently saw this music video with EsDeeKid and Timothee Chalamet and I have to admit, this accent goes hard on him.

[Yannick Kälber @YannickKae]

@W98AB Yeah, shoar lid

[Yannick Kälber @YannickKae]

@J_lacasse89 @__paleologo 👍🏽, it seems to be common among investment consultants.

[Yannick Kälber @YannickKae]

@istwine @istwine found another point:

The admissible region is in fact the exterior of a ball in Mahalanobis space. And this boils down to a simple lower bound on the regression's R^2.

[Yannick Kälber @YannickKae]

Extended it to multiple signals:

Thanks again to @istwine, who carefully read through it & correctly pointed out that the admissible region for rho is not a half-space ('cause the norm vector itself would have been function of rho).

[Yannick Kälber @YannickKae]

I’ve written a short note providing a more general & detailed derivation of @macrocephalopod’s heuristic from this nice thread.

If you’ve ever wondered about why "3 * beta", for example, here you go.
