    i'm at a loss of words after reading a paper about reformatting code using an ML model that has a measured statistical quantity A_c which says how often the reformatted code behaves the same as the original

    the "ideal" (their choice of words) case is 64.2%

    @whitequark "92 boosts, 115 favourites" damn

    I swear to god sometimes Mastodon is just "old person yells at thing".

    Researchers spend tons of time and money trying to solve Sudoku in polynomial time not because Sudoku is such a important problem to humanity, but because it's a NP-Hard problem, and you can thus reduce all other NP-complete problems to Sudoku and solve them all in polynomial time if you can solve Sudoku in polynomial time.

    The research challenge is disentangling content from style in a learned embedding space, it's a classic representation learning problem that's genuinely hard: 1) Two functions that do the same thing should have identical content embeddings but different style embeddings, 2) Style must generalise to unseen code patterns, not just pattern-match known rules, 3) It's unsupervised, so there's no labeled (code_A, same_code_in_style_B) training pairs.

    Code formatting is actually a very good medium to test this hypothesis, because you have an infinite latent space of code that does the exact same thing but is stylistically different.

          @budududuroiu the reason I was reading the paper is because I'm working on the same problem and I think the encoding presented in the paper makes no sense at all to use

            @whitequark to use for what? It's research, it's not meant to create something for industry use. Academia already suffers from the "File-drawer problem". I also did research on using GANs for Outlier Detection, when most of the time Outlier Detection is a classification problem, not a learned representation problem.

                            @whitequark Maybe they'd like their phone and car 64% functional as a real world test 😏.

                            Some of those logic misses/switches are disturbing. I don't know how it's allowable.

                            If the code works 100%, and "reformatting" it reduces that % then it's wrong by definition.

                              I think reversing the `j` for loop is actually wanted by them? It's labelled "ground truth", and it is a potential valid optimisation

                                  @ireneista @whitequark Now, show me the numbers on the effort to make a rule-based style file compared to this. Because I'm sure that A_c is 100.0 in that case.

                                          @ireneista @whitequark Now, show me the numbers on the effort to make a rule-based style file compared to this. Because I'm sure that A_c is 100.0 in that case.

                                          @GeoffWozniak @ireneista so the problem i'm solving is that while for C++, you have tools like clang-format which are nice and flexible, for Rust you have rustfmt which is rigid and makes your code look like ass. I do not like my code looking like ass but I am also receptive to the idea that introducing as many knobs as clang-format has into rustfmt would make it unmaintainable
