Apple Health seems to allow exporting all the data as a file, including individual measurements from the watch (those come every second some times). Haven't tried it yet though.

I'd add V. Arnold's books on Differential Equations and Geometry to that list. Wikipedia summarizes it nicely: "His views on education were particularly anti-Bourbaki." :)

Containers were not supported on Android last time I checked, a few month ago. No containers on iOS also. One more problem is that containers are an addon and do not sync between Firefoxes on different desktops. Still extremely useful thoug

re:conferences: That's not quite right. In conferences you also meet people, some of whom you knew before and some that you didn't. You get to talk, and ask questions. The ROI of this may be questionable, but it does have value.

The course you refer to and the paper are somewhat different. The course simply says that for a given problem, there are good datasets and bad datasets, and the bad data may be bad no matter how big it is. Bad means biased here. The paper c

What I find interesting is that gestures seem to be a part of the thought process itself. Its always fun watching people gesturing while speaking on the phone .

Return times of random walks are power law distributed in some graphs. For example return to an interval on the line.

If that's true, isn't there some organization in the government that can sue them for this?

>>UMAP has already demonstrated its efficacy as a tool in any data scientist’s belt. Any chance you have some references? All their examples in the UMAP paper and in this talk look very toy-like.

There probably is a similar effect when people look at their own photos versus other people looking at the same photos. Wonder if anyone experimentally verified that.

Well, lets try. For the embeddings, you'll have to search the internet for details, and this may be not a "proper" ML. But the general idea is that if you have some nice euclidean algorithm, like k-means, and you want to clus

I learned so much from Bourgain's work. While most of his work was in Fourier analysis, and later in number theory, he really was a very versatile analyst. Just two of his early papers, on embeddings of metric spaces, and on concentra

What I said is that "very few people cared" is a better description than a "25 year old problem". It is better because it better aligns with the facts presented in the Wired article above and other similar sources, due t

I read the article. I see how much published work on the problem is mentioned, and where is it published. In this case, not much. If a mathematical problem is really hard, and really important, of the type to reasonably qualify as a "2

Describing this as 25 year old math problem is a bit misleading. There might have been two or three otherwise not noted mathematicians that have looked at the problem a couple of times after dinner during the last 25 years -- is a better de

Well, p definitely is the solution in the case I mentioned. It is indeed the maximum likelihood solution. You could incorporate prior info about theta via a regularization term, if so inclined. What does not make sense in this? Not sure

Its quite important that its not so much about "non-convexity", its more about "random initialization". All these results, and there are others, more sophisticated, basically say that after random init everything is alre

This is not necessarily a trivial fact, but I wouldn't call it incredible. It says a net trained with gradient descent can fit the input perfectly if its much larger than the input. But this says nothing about generalization, i.e. per

by cosmic_ape 8y ago
Yeah. And they require that the number of parameters grows at least polynomially with the size of input . In this regime, we also have another algorithm capable of zero loss -- the linear regression!

Exciting. And the cache size is likely the main reason. But that can not be concluded from the analysis. >>VTune agrees, and says that Z3 spends a lot of time waiting on memory while iterating through watched literals. But how much i

This mentions ICA and NMF, but in contrast to those the proposed method is supervised learning, not unsupervised. I'd suggest the authors try something like an autoencoder in the waveform domain. That would be a more close analog to th

In linguistics there is also work that attempts to understand the formation of abstractions from sensor-motoric concepts. Here's one example: http://fas-philosophy.rutgers.edu/goldman/Spring%202008%20Se...
