yup. deeply regret my time as a postdoc. especially the last few years in the pandemic have been the absolute worst work experience in terms of culture and job satisfaction. it's killed the passion for research i had at the start. the

As an experienced mathematician once told me: "The way I read papers is by first reading the abstract. Then I try to state the results and prove them myself. When I get stuck I go to the paper to see what I got wrong." Mileage may

I think we're probably thinking of the same papers. There was a competition /session at last year's neurips and there's related papers linked from their webpage. https://www.ecole.ai/2021/ml4co-compe

There are ways (called heuristics) to solve some NP hard problems faster than exhaustive search. Of course, for theoretical reasons, a heuristic is not guaranteed to be faster on all problem instances. The general idea is to do some enginee

This would be my concern too. People fail to understand how in heatwaves there ceases to be cold air to move around. Everything heats up. It's brutal.

As someone who was in Europe for one of the heatwaves of recent years, and whose appartment was in one of these older buildings designed this ways with thick walls etc., I can attest that this only works up to a point . This design relies

FWIW I lead with this whenever I find myself teaching lin.agl. and I agree it's the most important point of context for students entering the subject (and presumably embarking on undergrad math).

Ditto. More broadly, I am bored by efforts to rehash the same introductory material from whatever your given technical topic is (math, programming, machine learning). There's already really good books out there on these things that hav

Blackwell is engaged in activist investing. Their goal is to make profit by changing how the company is run. This deck is surely part of that campaign. Thus it may contain truths, but it also serves their agenda. Best to be understood in th

The first thing to know is your goal. Your goal could be things such as: to glean core concepts and methodologies, to determine how a paper relates to another research work (such as your own), to find an answer to a specific question (or de

And this makes everything else in the survey easier. Topic sentences and presentation skills are useful but most important is having something original and substantial to say. The rest follows and is easy by comparison.

It's funny, I also think Euclidean geometry is a bad way to introduce proofs, but my reason is different from what you just said. I think what you just said is primarily about "writing proofs", which is certainly important, b

I cannot speak to whether this is still true for modern farm equipment for two reasons. First, my family ran a small livestock operation and older machinery was more affordable to buy/run/repair and fulfilled our needs. Second, th
