Nearest neighbors in high-dimensional data?
...ake sure that you really need all 21 dimensions and possibly find a linear transformation which would allow you to use less than 21 with approximately the same result quality.
Update:
I encountered them in a book called Biomedical Signal Processing by Rangayyan (I hope I remember it correctly). ICA...

What are the differences between NP, NP-Complete and NP-Hard?
...ecisely, Y is reducible to X, if there is a polynomial time algorithm f to transform instances y of Y to instances x = f(y) of X in polynomial time, with the property that the answer to y is yes, if and only if the answer to f(y) is yes.
Example
3-SAT. This is the problem wherein we are given a c...

How do I tell git to always select my local version for conflicted merges on a specific file?
... may have a config file template with tokenized values in it, and a script transforming that config.template file into a private (and ignored) config file.
However, that specific remark does not answer what is a broader more general question, i.e. your question(!):

How to use the same C++ code for Android and iOS?
...vert the JNI types to the types we use on CPP side. On our example, we are transforming the jstring to a const char * sending it converted to the CPP, getting the result and converting back to jstring. As all other steps on JNI, it is not hard; it is only boilerplated, all the work is done by the JN...
How can I reliably determine the type of a variable that is declared using var at design time?
... analyze the statement containing the interesting expression. We start by transforming it syntactically to
var z = y.Where(foo=>foo.
In order to work out the type of foo we must first know the type of y. So at this point we ask the type determiner "what is the type of y"? It then starts up a...

Is a statically-typed full Lisp variant possible?
...ure is what makes Lisp so good at handling symbolic computation, ASTs, and transforming Lisp code itself!
So how would you model such a structure in a statically typed language? Let's try it in Haskell, which has an extremely powerful and precise static type system:
