I can recommend it, it is a great primer on the subject.

For me the two moments so far have been seing computeurs winning at Go and knowing that basic quantum computeur are out there (even if they are not useful yet).

In his talk "Speed Is Found In The Minds of People" [0], Andrei Alexandrescu tries to make a sort really fast for medium sized vector and then closes on thoughts on this precise distinction. If this question intress you, it is wor

I don't think being practical hinders one's imagination (I would consider myself both imaginativ and very practical). I know of two school of thought regarding the origin of original ideas : - Original ideas stem from ignorance of

Book two happens after the conquest of mexico and I found it less interesting, you can safely skip it. Book one, however, has a surprisingly modern style and reads very easily. The headers of the chapters contain a summary of their content,

My understanding, after reading the memoir of Bernal diaz Del Castillo[0] (who was an eye witness of the conquest of Mexico), is that it was Montezuma II who purposefully spread rumors saying that the conquistador were returning gods so tha

It seems dubious because the FP community tends to use the expression 'immutable data structures' were 'persistent data structures' would be the proper term. As a matter of fact I have seen data structures, in FP languag

I love Rust but comes from an Ocaml/F# background (and, as others have said, the inspiration is palpable) and you seem to have a common misunderstanding around immutable datastructures. Immutable datastructures in functional languages

I concur with 1, as a reader living in a small flat I prioritize ebooks and try to only buy physical books when I know I love the author+serie. (but I am happy to say that I own a physical copy of the full laundry files)

And that's just the beginning of the story. The same thing happened to me. 10 year down the line the inside of the tooth has been mostly absorbed by the bone leaving it fragilized (which, according to my dentist, is a common occurrence

(4) is my main reason for missing C++17 when I am on a project stuck with C++11. I feel that the template metaprogramming framework deserves an overhaul to clean up historical mistakes and keep only the good part.

For the error free transform, the important part is the associativity and not the fusion (which would not degrade the operation). As illustrated in the Wikipedia page, if move terms according to associativ rules you can show that one of the

The authors ends by noting that FMA would probably have improved the performances for the Rust code. It is interesting to note that, whereas most ffast-math optimization will trade precision for reduced computing time, adding an FMA can onl

The one very important thing that often get destroyed by compiler using associativity is the TwoSum Error free transform which is a vital composant of several algorithms that deal with numerical error (most notably the Kahan Summation). The

Not competent on Ivis but UMAP is very good at making sure that points that are close in the original space are close in the output space. When you want to perform some sort of clustering on top of the dimensionality reduction its a very us

I am not the OP but I would say that UMAP is a clear superset of t-SNE being able to do the same thing but faster and with a better conservation of large scale distances.

PCA has speed and interpretability on its side but also the ability to easily add new points (UMAP has a quick fix to do so but its a hack) and go back and forth between the original space and the compressed space making it usable on a wide

Side note: there is some industrial use (and interesting work) for theorem proving in software verification and cybersecurity.

Do not hesitate to communicate on your project if you ever do that (maybe here: http://www.arewelearningyet.com/gpu-computing/ ), there is clearly space for a great GPU library in Rust.

With most kernels the matrix is symmetric and positive-definite so I would probably use a conjugate gradient: https://en.wikipedia.org/wiki/Conjugate_gradient_method

The raw mathematical formula uses an inversion but what you truly need is to solve a linear system (which is why most implementations store a cholesky decomposition of the covariance matrix) which can be done without transforming the matrix

by nestorD 7y ago
Another easy solution, if your kernel is appropriate (goes to 0 at infinity such as a Gaussian, Matèrn or Exponential kernel), is to set a threshold under which your covariance is set to zero and to use a sparse representation for the covar

You can also use the apriori probability of a positiv, instead of a cost, which can be roughly deduced from existing litterature. The strenght here is that you get rid of an arbitrary decision (p-value) and instead use quantities that can b

Small shoutout for 0AD which is a fully open source RTS in the style of age of empire and now very polished (my little brother, who was used to starcraft, is now playing it happily) : https://play0ad.com
