I know this is just a SM post. But one could argue that Finance (esp. the macro-structural tradition) is the more "adult" field in terms of its brutal enforcement of system-level realism than others listed. You misread the system, and you disappear. There's no safe "academic" abstraction layer. [+]
Many modern technologists and computer scientists are very cogent systems thinker because any sufficiently advanced technology *is people*, all technical systems are socio-technical. The capital T Tech dipshits talking about “alpha” are mainly cosplaying finance people, regardless of their training
This is absolutely the case. Tech Guys of previous generations, to the extent that that category can be read back into the 19th and 20th centuries, were shockingly well-read by modern standards

I showed this to my mother on Zoom just now and before I got an opinion on how it looked, it became about "why do I always need to collect trash." 😅 But before I could explain that I had no intention to get it, my father started to lament that she threw away all the old (even antique) rotary phones.
FYI: In trying to look up the phone model on the top post, I learnt that oldphoneworks (a reliable source for refurbished phones) no longer ships to the US. Also found this handsome phone while looking up the above (and looking up for pre-1920 non-brass examples).

Just recently got an invite for a workshop in Sarajevo, and then another one immediately after to teach ML at a winter complex systems school in Petnica (about an hour from Belgrade). Of course, it's just at a time when I can't travel/leave the U.S. :-/

These can still be obtained. Although it can be a challenge to get nicely refurbished ones (unless they are of brass).
As one of the first table top phones, these were certainly an identity purchase.
These marked a shift of communication moving from the public to a more private interaction before eventually going public again.
This phone served more than a way to talk. It served as a social and practical anchor.

Merely the pattern match from the post reminds of a book from a few years ago. I liked the idea enough to pull all stops to get a copy from the publisher almost 1.5 years before it was published. This reminds me: 1) I should read it again, 2) Should get a prettier copy.

What people are actually trying to say: Natural data distributions live near a low-dimensional tame geometric object. Neural networks can represent functions whose images are also tame. PS: This implies learning is possible because both sides reside in the same o-minimal universe.

An important reason to fix reviewing (solution is simple, by the way: phase out double blind) is to reduce the whole "If it were not for rectangular-headed reviewers, we were winning the Nobel Prize. Scholarship is dead, etc." shtick. Tired of this every cycle.

Index space estimation (both single-/multi-index) used to be a niche area of semi-parametric statistics--had strong intellectual lineage, but was still isolated, and disappeared in the SVM era. It seems to keep resurfacing in ML now, and I am not quite able to understand why.

The solution is to phase out double blind reviews, make reviewing compulsory for authors. f1000 shows how this should be done. Nature also gave you the option to reveal your identity after the process was complete (I see that ARR has been experimenting with it last two cycles).
All the slop review drama unfolding at ICLR is painful to watch. But having so many eyes on it puts us in a better point to find solutions. This would have taken longer to be exposed on a closed platform where we may have had a few screenshots and a few author stories at best.

Recently came across some scanned copies of incunabula around the travels of Marco Polo. There are many versions and lineages. But one caught my eye--annotated by Columbus. In looking around, found that copies from each lineage were in the Vatican library. After some time the obvious inference

For the past couple of years or so, whenever I feel like I am on top of most things, and start feeling good about it, I soon realize I have 4-5 papers to review still in the queue. We just finished ICLR, ARR, AISTATS, and there are still more (this time from journals; CVPR isn't out yet).

This chart is apparently very popular. I have a lot of thoughts on each point in this thread, but not sure they are worthy of explication, so I'd just reshare. I'd only say that stock markets' (unlike currency and bond markets) adolescent character is often misused both ways, even by individuals who
This chart IMO is showing a rebalancing story under the constraints of a wider global debasement trade. it is not showing a policy story (at least not directly). Stocks don't reflect policy in the short term, they reflect allocations. Yields are a better barometer, and you see them degrade all over.
I can't tell you how many interviews I've done where I've been asked: If Trump's policies are so problematic, why are U.S. stocks rising so rapidly.
A bit of international context illustrates the real issue here.
U.S. stocks have dramatically underperformed other advanced economies.

Working with a good (or disastrously bad, or usually both) lawyer or doctor is often the first time people feel what "domain expertise" really means. Otherwise stakes are often removed, and the concept becomes too abstract.

"Recruiting PhD students" is accurate technically and reflects the reality, yet the framing feels entirely wrong, in a much broader symptomatic sense (e.g. students as budgetary instruments; framing doctoral advising as staffing a corporate-style grant-funded research operation etc).
