alpineidyll3··on AWS doesn't make sense for scientific computing
We'll put. My company is current suffering through this...
alpineidyll3··on Nobel Prize in Chemistry Awarded to Bertozzi, Meldal, and Sharpless
The exception: a well deserved nobel prize.
alpineidyll3··on Tesla AI Day 2022
It was pretty funny to watch them claim to be the world's leading ai and robotics company" after failing to outwalk the decades old products of Boston dynamics with an 800x smaller market cap.
alpineidyll3··on The anatomy of an ML-powered stock picking engine
If you can read and understand bergomi's book you basically understand financial math
alpineidyll3··on The anatomy of an ML-powered stock picking engine
No. Because to train the sentiment model you need estimable distributions.
alpineidyll3··on How history/tech YouTube channel Asianometry reached 270K subscribers, $5K/month
By being an indispensable, well-researched, source of information! That's how. I catch every bit of content from this person. I can't believe they choose to operate in China, I'd love an entire video just on that. Wish them the best.
alpineidyll3··on The anatomy of an ML-powered stock picking engine
My heart goes out to this author, but you can tell even by his first table that he doesn't quite understand the mathematics of financial markets, the purpose of a hedge fund, how they grow etc.

1) It's plain by quickly looking at the allocation of capital in investment firms, that AUM is not made by performance; it's marketing. At best people invest when they believe a person is connected to inside information. Saying you have an ML advisor is really just a pre-req to these people.

2) Is that allocation stupid? No, it's not, because actually the powers of mathematics and by extension ML are intrinsically limited for investment returns because they are fat-tailed </Taleb>. For example this author quotes a realistic sharpe (0.8), but didn't calculate the standard deviation in his sharpe, which I would bet a large sum was _at least_ 0.8. Ie: he doesn't really know what his sharpe is. This is because equity assets behave like a student-t distributions with a degree-of-freedom parameter ~2 or less </Mandlebrot, /Bergomi, /Gatheral etc.>. Ie: higher moments such as uncertainty in sharpe, literally do not exist or converge and are unknowable. The only exception is if your strategy explicitly cuts off tails.

Once you understand 2) you begin to understand that there's no such thing as a real quant fund (ie a fund which truly makes money predictably using models) which doesn't trade a liquidity limited book that has quite advanced hedging. Wealthy people are aware of this, which is why the author can't market this product.

If you're doing something silly like holding equities without tail risk control, you literally cannot be quantitatively investing. You are just slowly rediscovering what Kelly, Bergomi, Mandlebrot, Bernay's etc. realized with a little deep thought over pen and paper (while clumsily writing boilerplate software.) That markets are entropy machines rougher than a normal distribution, and any gains come directly from information. (see: Kelly: "a novel interpretation of the information rate".)

For a high latency (ms) market data feed, the returns on information are very very small. Markets are efficient.

alpineidyll3··on New York City’s Empty Offices Reveal a Global Property Dilemma
It's actually the tax write offs for vacancy which have shelled out American cities. I wouldn't expect them to go away anytime soon though.
alpineidyll3··on 3x new books added to the Pirate Library Mirror
Its really a false dichotomy that freely available information deprived creative people from making a living.
alpineidyll3··on 3x new books added to the Pirate Library Mirror
Anything I've ever done is freely available! I have several homes. So yeah.
alpineidyll3··on 3x new books added to the Pirate Library Mirror
It boggles my mind that people can only mention that this resource is illegal without pointing out it's the best library humanity has ever made.

It has been the goal of the Google cofounders, Carnegie, and great civilizations since antiquity to make something like this.

Are people's thoughts really so moulded by their surroundings, that they cannot recognize a wonder in front of them?

alpineidyll3··on Pay attention to deviations from mainstream incentives
Excellent piece. Definitely a better than average think piece site too. Cheers to exolymph.
alpineidyll3··on What exascale computing could mean for chemistry
You're right.
alpineidyll3··on What exascale computing could mean for chemistry
100% agree with this. Although mini-batch SGD is much more parallel than most problems.

the scientific codes which parallelize poorly often parallelize poorly because they are written in ancient languages with support for whatever supercomputer interconnect bolted on poorly, Whereas TPU's + JAX have beautiful functional abstractions for distributed tensor computations.

Just funding re-writes of all the basic math/physics stack into a language with a PORTABLE parallel functional design and perhaps a compilation layer would definitely get more basic science done than this thing.

alpineidyll3··on What exascale computing could mean for chemistry
Well put. Of course Anton's Force field isn't accurate enough to correctly predict conformational equilibria of proteins ;P although it does scale!
alpineidyll3··on What exascale computing could mean for chemistry
If your pde has spatial locality, parallelization works. I suspect you might be talking about multidimensional diffusions such as occur in finance. These decompose locally in price space. If the pde is nonlocal there is very little that works in general. I wrote a paper on parallelization in the time dimension, but it works poorly.
alpineidyll3··on What exascale computing could mean for chemistry
If you understood anything about how literally every chemistry problem scales non-linearly, and requires exponential amount of sampling to yield any predictive meaning you wouldn't talk about things you don't understand lol. Peta=>Exa equals 1000x so you can get 31x the accuracy in a monte carlo assuming perfect parallelism (at 1000x the cost), and that's one of the better scaling things it could be used for.

It's fun to have big toys sure, it's fun to make big GPU clusters. But if they spent what they spend on this computer, on just funding students to solve problems and toss them a 3090 100000000x more scientific breakthroughs would happen. This machine is 60% paperweight, at best, with a hefty budget for good old fashioned contract pork.

alpineidyll3··on What exascale computing could mean for chemistry
I have my Ph.D. in this exact field from UC Berkeley. My thesis was about polynomial scaling algorithms for quantum molecular systems. I was a postdoc at Harvard. I received an NSF career award. I know exactly what I'm talking about lol.

These computer platforms are drastically inefficient on a flop / $ basis. They exist to funnel money into the pockets of the companies who assemble them. They never ever achieve even a tiny fraction of their peak rated flops on any calculation that has any scientific meaning.

alpineidyll3··on What exascale computing could mean for chemistry
This is exactly like if you were to ask: what can exascale do for larger scale quantum simulation.

Not much! These devices are vanity projects and prey upon people's intellectual blindness in the face of giant numbers.

alpineidyll3··on The Scourge of Rent Control
It's funny, in areas I deal with daily these second order effects feel obvious and make me scream daily. I had to read your good comment 2x though. Perhaps I'm under slept, or perhaps this is a sadly durable failure of the human mind.

alpineidyll3··on Oxford Physicist Unloads on Quantum Computing, Says It's a Hype Bubble
I'll get downvoted into oblivion for this, but dozens of my old academic friends from Harvard are in on this grift. My old advisors own some of the largest enterprises in this 'sector', and all all these people (in private) regard quantum computing as a money grab. At best, as a way to fund research.

And that's it! The author of this article is 100% right. Markets are fully aware though, go ahead and try to short any publicly traded QC stock. You can't. There's no shares to borrow and no liquidity on puts...TRUST ME I"M TRYING TO :P

These enterprises will continue to offer regular old data analysis dressed-up with quantum storytelling as a prestige tool. That is also the business model of many many very large companies (consulting etc). So it's possible these companies might even do fine, but not because they will have a computational advantage-- Not with these platforms.

Well done little app. I assume it's a project for funsies? source?
alpineidyll3··on Jeremy Grantham Warns ‘Super Bubble’ in Stocks Has yet to Burst
This dude has been saying this, literally forever. This type of financial press exploits the same human Cassandra bias as any other doomsayer. He doesn't know the future better than anyone else.
alpineidyll3··on Scientific grant applications are getting heavier on hype
That's sad because grant panels approve based on political and personal relationships, not the content of the grant. Lol this is like complaining about mafia talking about cannoli....
alpineidyll3··on Preventing an AI-Related Catastrophe
People often think of AGI as an AI which can learn to complete arbitrary tasks better than humans.

Given that we already can produce "an" AI which beats humans at almost every task we come up with (besides synthesis of broad abstract reasoning, a-la Chollet) this is probably the only definition which is meaningful in the sense that it isn't already here.

Why would evading 'alignment' not also be such a task AGI does better? AGI is like the nuclear deterrent. It's a technology thats coming, inevitably, and a thing which is beyond any amount of philosophical navel gazing to control or prevent.

AGI's will not be magical, they will have energy demands, construction costs, and environmental limitations.

I think it will be much more useful to ask how people coexist, and what role they serve in the post-AGI world, than it is to make statements about interperability or alignment, which will definitely seem silly in retrospect. The machinations of an AGI will be as impossible to understand, as human consciousness itself.

alpineidyll3··on John Carmack's new AGI company, Keen Technologies, has raised a $20M round
I hate the pop sci ill-defined notion of AGI. As soon as a task is defined, an AI is developed which completes the task from real world data with superhuman success. The work of making the superhuman model isn't even conceptual usually, it's a matter of dispatching training jobs. It's quite clear that if your definition of AGI is superhuman perf at arbitrary tasks, there's no conceptual barriers right now. Everything is mere scale, efficiency and orchestration.
alpineidyll3··on Monkeypox: 25K cases, a batch of new deaths, and 3 state emergencies
Monkeypox (like COVID) causes undeniable, obvious symptoms. How many less obvious virii are circulating at all times? How many are causing fatalities? How should we estimate that and what should we do about them...

Media impact and counter-reaction probably made COVID worse in the US... We need to stop doing public health policy with the news.

alpineidyll3··on Could we reboot a modern civilisation without fossil fuels?
No.
