Weekend project on signal separation: How can we isolate a weak, nonlinear signal when it's mixed with a dominant, linear one?
Would be a massive loss for Meta. There's quite a bit of interesting work that came out of FAIR maybe that's overshadowed because it doesn't directly impact the AI race. Wrong to underweigh that work. There should be a space for this kind of work.
Breaking news: Meta’s chief artificial intelligence scientist Yann LeCun, a Turing Award winner who is considered one of the pioneers of modern AI, has told associates he will leave the Silicon Valley group in the coming months. on.ft.com/4ozjBGl

Kim Kardashian expresses her frustration in new TikTok vlog over psychics who told her she would pass the California bar exam, only to fail.

Going to attend neurips this year for the first time. I hear it's a gigantic event, though I don't really know what to expect, I'm excited to be surrounded by researchers and engineers. I'll be on the lookout for everything loosely related to representation learning.
Does anybody know where I can find the list of tutorial/workshops at neurips this year?

What's annoying about Trump announcements is that it's engineered to manipulate markets making trading an even more stupidly volatile hobby than it already is. Can't count the number of times I've observed this live wondering wtf was happening & it's just him shitposting from his truth account.

I started using deep research a couple months ago to do literature reviews. At this point, is there any point in doing like I previously did (extensive search on google scholar using a variation of keywords on a loosely defined topic). Anybody still just do google scholar these days?

Stochastic government, $2000 stimulus, 50 year mortgages, cannot wait for what's coming next week

50 year mortgage is so crazy. to put it in perspective, 2016 was 50 years ago

This fourth season of the Witcher has James Malfoy and Lawrence fishburn two of my favorite actors. Why did I not watch season 3? This show has a tendency to be a slow burn, borderline boring.

I have seen way too much of Alex karp, palantir CEO, lately. He's trying to outdo Musk if that's even possible.

By the way if anybody on here has quite a bit of experience in signal processing and fourier transforms, I would like to DM you. Let me know.
I have a question on basis functions, what they are and what characteristics of theirs are desirable or not

I do not know why it took me so long to finally sit down and start learning more about signal decomposition (i.e. fourrier and other transforms). Given how much time I've spent dealing with matrix decomposition (pca, nmf), other graph embedding (umap, tsne), and linear factor models and even VAEs.

I implemented a ddpg rl algorithm at work in 2020, and quickly exited that company and forgot about rl. Surprised to see that ddpg comes up all the time in RL to this day. It's that good of an algo?

When the movie about the AI bubble is made, the scene where Sam Altman tells one of his investors to sell his shares after asking Sam how a company with $13B in sales can make $1.4T in commitments will win the actors an Oscar.
It’s that absurd yet emblematic of this era.

In 6 months we'll get stories about 3 people who actually left NYC after Mamdani won and they'll say shit like "I couldn't bear to see my city destroyed" and then it will turn out they lived there for 9 months but had no friends so they went back to their parents' 2nd home in suburban St. Louis

First time in East Africa (Uganda) and I am having a good time. I keep being offered fruits (Pineapples and Mangos) but I only have eyes for plantains. Ate roasted plantains off the street, and decent fried plantains too. Having a blast.

Trust me, I already largely do. My default stand is most media are fake unless verified by trusted sources.
Sora is not the real problem here. The real problem is that in 12, at most 24 months, there will be a Sora clone from Tencent or Alibaba that is just as good and can be run by anybody with a 5099, at which point everyone in society needs to rapidly agree to treat all digital video as fake, period.

One of the best staff-level engineers I worked in the past with is on the market.
This is someone who will not fire off a single job application: already interviewing at companies where ex-colleagues heard he's on the market. Even if not hiring, they are creating space for him.

With this logic I should have given up when my ugrad was terrible despite doing well in high school. Life happens, remember that!
Klein had a 2.2 HS Gpa.
Now I’m not saying high school is the be all, but if your parents are profs and you can’t learn the easy game that is HS school, well that’s a bad sign.

phase transitions: since economic systems are dynamical, if pt exist they should be dynamical. I didn't study dynamical pt, are they essentially the same except for the time component? For the 1st order you look at discont 1st derivative, and 2nd order discont 2nd deriv?
