The problem you mentioned is not the one that is being tackled. The real challenge is that being blind to just race isn't enough . For example, zip code is often highly correlated with race, so using zip code to predict whether an app

In this case I don't think what the article says is exactly right. Naively, tensors are just n-dimensional arrays, which TensorFlow supports. The paper linked in the article appears more to be talking about how derivatives of tensors a

This is far from a new idea, and is called the "hidden-variable theory" [1]. In fact, it has been mathematically proven that locality and hidden variables are fundamentally incompatible in the context of quantum mechanics. [1] ht

They do two things. First, you get right of way (so highest priority). Second, the only cars they do not stop are right turns. As other commenters have mentioned, the point is to improve efficiency, both since cars can turn right once there

Google's original rational for exiting China was to protest suppression of information. Has it done anyone any good? China simply developed their own search technology in house to replace Google, but with censorship. By doing so, they

Thanks for the response! I think you're right that it's something along these lines. I didn't find any further information about Euclidea, but for anyone interested, I did find some information about open source engines that

Does anyone know what are the algorithms behind this game, i.e., how does the game decide whether a given construction is valid? I'd appreciate any pointers!

It's probably easier to give an example of a number that I can't represent symbolically. However, I can't give you a specific example, since if I uniquely define a number then that definition is itself a symbolic representati

This is an issue if the non-AI company using humans is not profitable (supported by VC funding) with the goal of "eventually replacing humans with AI". If they are not transparent to investors about this point, then investors may

But... aren't they? It's one share one vote, not one employee one vote, but I think that still qualifies as democratic. Then, there are elected board members (the representatives) who hire the CEO (the prime minister?), etc.

I think "dynamic" is not such a bad term either -- the original application of DP was to optimization in dynamical systems.

Though the other comments are correct, I want to point out that you can get some nontrivial behavior with only linear functions. For example, low-rank matrix factorization is kind of like a neural network f(x) = U * V * x, where U is an n b

But a huge part of the problem is that many users of facial recognition software will not be experts on how to properly use the software. If the ACLU improperly used it, do you really trust law enforcement agencies to do a better job?

Perhaps we are looking at a different graph, but in the one I am looking at, blue is "sparse" (plateaus at 70) and orange is "dense" (very quickly hits 80). I believe "dense" means they are doing reward enginee

I think this is quite impressive. I'm a bit confused about the section saying that "binary rewards can give good performance". Is it saying that binary rewards (instead of continuous rewards) work fine, but end-of-rollout rew

I think the "simple random search" algorithm in the paper you linked is not so simple -- it's basically using numerical gradient descent with a few bells and whistles invented by the reinforcement learning community in the pa

Can you clarify why variance only scales linearly in the duration you are optimizing over? I would have expected it to be exponential, since the size of the space you are searching is exponential in the duration.

Very little of what goes into a current-generation self-driving car is based on machine learning [1]. The reason is exactly your point -- algorithmic approaches to self-driving are much safer and more predictable than a machine learning alg

D-Wave is not a "real" quantum computer in the sense that it is not asymptotically faster than a classical computer. Quantum computers with very few Quibits have existed for a while -- I believe the current record is 17 quibits [1

Couldn't this finding be explained by the fact that the hospitals with lower readmissions tend to be poorer (since poorer patients are less likely to be able to afford care)? I only took a quick look, but I didn't see how the pape

Why would disolving the FDA fix the problem? If you don't do clinical trials to establish efficacy, then how will doctors know which treatments are effective and which ones are bogus? Randomized trials are important here due to the cau

As many other commenters have pointed out, it is possible for net global wealth to increase (e.g., the increase in total real GDP). As far as I understand, the main reason this is possible is the development of new "technology" --

To be precise, negative energy prices are good for consumers with flexible energy usage (and bad for other consumers). For example, if you have a battery at home, you could charge it when energy prices are negative and use the battery when
