Synthetic data uses the distribution(s) of the underlying dataset(s) to generate a totally new dataset that in theory has the same statistical properties of the original dataset. The rub is in making sure that you're actually synthesi

What you're basically describing is compressive sensing. The basic idea is that if you can find a domain in which your data is maximally sparse, then you can transmit the same information with many fewer bits. Unless you're extre

Yes, use a dedicated job server/process like Celery.

The errors are most certainly not random, especially in hypertensive patients who are most likely to purchase these devices. Hypertensive patients can show large variability in successive BP measurements just due to arm position.

Just about every modern language has a well established R-tree library...

I did read the article before posting. They don’t actually explain why they opted to not use an R-tree except to say that they think this organizational structure makes sense intuitively. Unfortunately, intuition here is wrong, and the link

Let's just ignore the fact that in this case scale has nothing to do with the actual efficiency of the algorithm they implemented. As the link I posted mentioned, had they used a more efficient algorithm they could have used far fewer

The entire line of argument would have been immediately rejected in a phone screening or an on-site interview at any of the major companies, and even many lesser companies that deal with spatial data. Anyone doing spatial queries and not u

This is a very inefficient implementation. Really, just poor quality work overall, as anyone with even a basic understanding of spatial indexing would know that an R-tree would be many times faster, as illustrated here: https://m

The price is what it is because of excessive governmental regulations that have artificially driven up the cost of housing to astronomical levels. At the end of the day, the homelessness problem in SF and other west coast cities is the resu

I really think that Elon Musk alone may cause the next AI winter. The guy has overhyped AI/ML to a crazy level that it clearly cannot perform at yet.

That's a big problem, and if true would probably invalidate the results. I would guess that AlphaStar was giving unrealistically complicated orders, or more likely tons of orders on opposite sides of the map simultaneously, a feat tha

There is a third option here. Instead of a blanket ban, or selective enforcement of "fact checking," we could neuter the utility of online political ads by simply requiring similar disclosures to what you see on television and by

No, it would mirror the European experience. Essentially just capping the cost of tuition, fees and room/board and subsidizing the schools to an extent to make up the difference.

In a privatized system student loans would be dischargeable under the existing bankruptcy laws, as they were before Congress changed the law.

No, it's not a better outcome than if the market was private because frankly no one would graduate with $150k in debt for a degree in basket weaving if private lenders were backing the loans. A well regulated private market would prev

I was in a PhD program, and left because I realized that I didn't really want to be there for another 4 years to finish after my Masters degree. I think the problem with academia is that you are always around very intelligent people wi

No, this is a common misconception. Consider the difference in electrical potential between two trees that are 35 feet tall, and one that's 20 feet tall. Is there a difference? Yes, but it's not a big one, and when you consider t

Sure, Uber will be sustainable, but only when the price of each ride increases to the point where Taxis are price competitive again. At which point, why would people use an Uber, when they can use a taxi at the same price? There are benefi

But that's the rub. Biological systems are not just random interactions. The entire system is meticulously orchestrated by DNA, RNA, etc. We don't even fully understand yet how it all works together, but it's very clear that

You're going to have to be more specific about what constitutes a major advance forwards. So far DeepMind's work (while impressive) has proven to be very brittle, and not transferable without extensive "fine-tuning". Pr

These guys are following the Uber business model. Burn as much cash as possible up front to generate buzz and big numbers for the IPO, worry about profitability later. The problem is that, as Uber has shown, profitability never comes. Pelot

Yeah, it's strange to me that the people working in this subfield are proposing more exotic approaches to basic time migration which is ideal for this problem and has been known for more than 50 years now.

No, compressed sensing only allows you to attempt to reconstruct the original signal from a limited subset of the data sampled in a specific way, as long as you can assume some kind of sparsity on the data in another domain. Fundamentally,

So we have the fake outrage here over working with a government organization to enforce the law (which you may disagree with, but it is still the law). Meanwhile, Apple, Google, etc all get a free pass for working with China, which is doing

As someone in this space, I think that most people vastly underestimate the actual practical considerations in converting a neat CNN or ML algorithm into a usable product. It's trivial to use the newest flavor of ML to write an academ

It's a great idea, but I can't believe that the market is that large for this kind of data for 2 reasons: 1 - there's certainly a point of diminishing returns; and 2 - having good, clean data that's proprietary is a _hug
