genann is also a similar small neural network library written in C.

#42What exactly is the output of the example in `test.c`? I.e. what do the numbers mean? The error in the prediction I guess, but the prediction of what? What is the first entry in the semion data set? a "0"?

#43Cranium is another alternative that uses BLAS for efficient matrix operations.

It might be easier to answer if you explained why you think it would be better. There may be cases where by-reference (yes, that's an absolutely acceptable thing to say, even in C) is more efficient: If the struct is a kind of "this pointer" (as in object-oriented programming) that is passed to a bunch of functions but relatively rarely used , then passing it by reference causes much less register pressure. Passing i…
> There may be cases where by-reference (yes, that's an absolutely acceptable thing to say, even in C) I don't want to be nit-picking. But I would like to know why "by-reference" is an acceptable thing to say. When I learnt C, C++, Java, etc. I was repeatedly told that pass by reference exists only in C++. In C, a pointer is passed by value. In Java, a reference is passed by value. Doesn't calling "pass pointer by va…
What do you do when you want to find the value a pointer points to? You dereference it of course!
C++ and Java have their own specific language-lawyer definitions of the word reference, but outside of those languages, "reference" is a catch-all term that includes pointers, handles, and indexes.

It's not shitposting. One of the core requirements of modern deep neural networks is performance. The high accuracy you get from very fast training over large amounts of data is the only reason to look at neural networks over very fast, very accurate systems like XGBoost. If something doesn't deliver that, then it's worth pointing out that it is inadequate for anything but toy tasks.
It's not really worth pointing this out when the thing in question is a 200 line C library. People won't be expecting it to save the world and/or butter their toast.
+1 also these tiny libraries are great for learning the basics. All of the code has actual meaning behind it and it's super easy to get it up and running.

No kidding. Does the output mean "hot dog" or "not hot dog"?

Generally when I see links to github projects on HN I expect something useful or extraordinary and this looks like my Neural Networks 101 assignment, only far more polished. But people seem to like it(over 400 stars right now) so maybe I am missing something.
Lucky you to have a neural networks 101! My CS degree is now 12 years old, and I crave simple examples like this one. Hence the upvote.

No. You definitely don't want to look at C code when you want to learn NN basics.

There is a ton of much better tutorials online (e.g. [1]) if you want a NN 101 course.

So... if its usefulness is equal to something you've made, AND it's available to the public, AND it's more polished... why exactly are you shitposting about it? Let people enjoy things.
Please make your point without gratuitous inflammation like “shitposting”. Its effect on the threads should be apparent, and we're trying for better here.
