As someone who's spent a lot of years in an academic social science field and in analytics/modeling more generally, I feel strongly that most educated people have way too much trus…

I'm very skeptical that this will succeed. As with other extremely hyped social medias (anyone remember Clubhouse?) it's already filled with influencers and e-celebs trying to get …

Having worked in analytics at various tech companies including Fb, the reason is almost always just that app users have way higher usage rates and ad clickthrough rates. Of course …

The paper does not claim that firms have increased profit margins: "the limited available data does not point to a widespread increase in markups" https://www.imf.org/en/Publicatio…

I find this an extremely odd and uninterpretable article for this reason. When people say that "x drives y" they usually mean that "x causes y". And inflation is by definition pric…

There is a stop sign in front of my house and probably around 95% of cars stop, and the amount of cars that completely ignore it (ie don't even slow down) is easily <1%. I think th…

This class of startup, "build domain specific LLMS using your own data", is extremely crowded right now but I am not optimistic about their future. For large companies, the actual …

Thank you, I appreciate your transparency with this work.

Most time series models assume you've already deseasonalized your data in advance. Typically, seasonality is obvious to the human doing the modeling (e.g. sales being up near Chris…

These shape matching questions are the problems asked in the study: https://www.researchgate.net/profile/Jordan-Barbone-2/public... I would bet that quite a few people just guess w…

At work we were facing this dilemna. Our team is working on a model to detect fraud/scam messages, in production it needs to label ~500k messages a day at low cost. We wanted to tr…

You could make a nice living covertly selling the AI "startups" to wealthy folk who just want bragging rights about being founders.

Great article. This part especially rings true to me: "If researchers have an ideological bent, a meta-analytic null may just be an expression of the typical sentiments of research…

I do not remember the specific metrics, but there was a big focus on the fact that their CPC/CPM/etc was lower than alternative social media, meaning advertisers put less value on …

The 42% stat is not correct, the poll in question has that 42% of US has not heard of chatGPT, only 14% of US has used it. https://www.pewresearch.org/short-reads/2023/05/24/a-majo…

I had a job interview with Reddit last year for a modeling related position and it was one of the strangest and most user-hostile interviews I've ever had, even as someone who's sp…

Quite a few do - here is databricks https://www.databricks.com/

I am skeptical that this is due to any positives on the NYC side, but more a story of the Bay Area's decline. Of the 796 US cities with 50k+ population, San Francisco ranks 796/796…

I find this article to be too high-minded. Most Americans don't own cars or support car-friendly policies due to some notion of car=freedom or some other culture wars nonsense. Ame…

It does feel like there are more and more startups every YC batch that are just cynical cash grabs. For example, all the recent LLM-related startups that are just UI wrappers aroun…
