What is this paper standing on?
No paper stands by itself. Each one adopts a method from somebody, argues with somebody else, and takes a handful of things on faith without saying so. Keystone reads all three out of the paper’s own sentences.
Not a summary and not a guess. Every relationship below is quoted from the LaTeX, shown with the words that placed it, and pinned to the pixels on the page where the paper admits it.
Or read your own
Any paper on arXiv that ships LaTeX source — about nine in ten. It is parsed on the way to the page, which takes a few seconds the first time.
A citation is not a neutral pointer
“Following Ba et al. we normalise each layer” and “unlike Ba et al., we normalise across the batch” are opposite statements about the same paper. The difference is written down, so it does not have to be inferred.
Assumptions are announced, then forgotten
“We hypothesize”, “for simplicity”, “it is well known that”. Each one is quoted verbatim next to what the paper offers for it in the same sentence — a citation, its own evidence, or nothing at all.
Every line is checkable in a second
The words that placed a reading are shown beside it, and a click puts you on the page where the paper says it. A reading you cannot argue with is just an assertion in a nicer font.
