My research group at Stanford has been alpha testing Tinker, it's both very useful and also really technically impressive in my opinion. It's a unified framework for post-training …

In fact, the shoe was not banned and it is one of the most widely used marathon racing shoes out there. Nearly all other running shoe companies followed suit and made more efficien…

Statistical physicist here. Negative temperatures occur when a system has a finite number of high energy states. On average, when temperature increases, both the energy and the "ra…

Convolution is in fact multiplication in Fourier space (this is the convolution theorem [1]) which says that Fourier transforms convert convolutions to products. 1. https://en.wiki…

Came here to make the exact same comment, agree completely!

I follow court news pretty closely and was genuinely curious about this decision. Here is a brief description of what I understand the decision to mean (I am not an expert by any m…

I follow SCOTUS news pretty closely; the discussions below are a bit misguided. Audio transcripts of oral arguments are already widely available---you can even subscribe to the Oye…

As many have pointed out, this rediscovers Newton's method. The reason that this type of approach with a "hessian pre-conditioning" is not widely used in practice is that computing…

In the chemistry / molecular biology community, that is definitely part of the role played by a journal like Cell. It is considered a very prestigious journal and tends to publish …

This is a fairly bizarre way to rank academic institutions. First of all, the methodology almost entirely neglects computer science because its metric of success is papers publishe…

As a statistical physicist, the title of this article looks the way "Two new papers explore the complexity of neural networks" might to a working ML researcher. Bubbles and foams a…

It's a good question: you can see a fairly granular breakdown of the workforce by industry [here]( https://www.bls.gov/cps/cpsaat11b.htm ). There are about 5.1 million people worki…

It's probably worthwhile to think about scale in this context: There are only 85000 H-1B visas issued each year by the US; 20k of those are reserved for people with advanced degree…

In NYC, I would say the average at an upscale place is about $3 for a cup of coffee, more like $5 for a cappuccino or similar espresso drink. With tip, I often end up spending $4-$…

I have been using Ubuntu on and off since about 2005. Last year I switched from OSX on a dated macbook to Ubuntu on a newer Dell XPS. On the whole I am happy with the switch: with …

It's an interesting and complicated question, but it seems like the coinbase business model should be pretty dramatically affected by the massive sell-off. First, as prices go lowe…

The article concludes that it is acceptable to stay on Facebook, but I take issue with its approach. Underlying the logic is a premise: that because Facebook is used by some to spr…

Currently, for "hybrid" journals, the researcher must pay a publishing fee, typically on the order of $2000-$3000. I have an independent postdoctoral fellowship, which means I have…

I have found that the machine learning research community uses twitter pretty effectively. I don't tweet myself, but I do follow a good number of other researchers and often find i…

One peculiarity of the academic system (true to some extent in start-ups) is that people transition from researchers to managers without any real training or evaluation of their pr…

The MPIs are set up as director-driven research organizations. There is one person, typically a very prominent scientist, that oversees a group of junior faculty (who I believe hav…

I'm a mathematician, but I work on things that are not even remotely related to the Riemann hypothesis. I could not possibly weigh in on the validity of the proof. My colleagues wh…

This write up not only oversimplifies, but it totally neglects one of the more interesting motivations of the original paper [1]. The authors are probing whether or not quantum mec…
