  A good company will use both. AI does 80% and a human does the final check.

    I once did that, still was quite bad.

  This is actually one of the best use cases of LLM. Indeed there is culture and nuance that may be lost in translation, but so does every other translation. And most of the time, if we know the literary art being translated ahead of time, we can predict a higher use of more nuanced language and adjust accordingly or skim it by a human.

  After all, most “AI” is basically feature embedding in higher dimensions. A different language that refers to the same concept should appear close to each other in those dimensions.

    No, it’s quite simply not. At all.

    LLM is an entirely statistical model. To the degree that it strings words together in an order that makes some sort of sense, it’s ONLY because those words are statistically likely to be strung together in that order.

    Japanese is an extremely imprecise and contextual language, particularly in its written form. Most kanji have multiple meanings, and often even a notably wide range of meanings, so a purely statistical model is already handicapped in any attempt to translate the intended meaning to another language. And Japanese creative writing, and manga especially, depends heavily on deliberately unusual uses of specific kanji to convey subtle bits of background information, moods, attitudes, hidden meanings or the like, or just as wordplay - puns, alliteration and the like.

    And LLMs have no way to recognize any of that nuance. All they can do is regurgitate the most statistically likely string of words.

    That will likely provide tolerable results with something that’s written simply and straightforwardly, but as soon as it gets to any of the countless manga that rely on unusual kanji readings and wordplay to convey nuance, it’s going to utterly and completely fail, since it has and can have no actual understanding of the author’s intent, so no basis on which to choose the correct reading of the kanji. All it can do is regurgitate the most statistically likely one, which in those sorts of cases is the one that’s absolutely guaranteed to be wrong.

      A word strings together form a sentence which carries meaning yes, that is language. And the order of those words will affect the meaning too, as in any language. LLM then will reflect those statistically significant words together as a feature in higher dimensional space. Now, LLM themselves don’t understand it nor can it reason from those feature. But it can find a distance in those spaces. And if for example a lot of similar kanji and the translation appear enough times, LLM will make the said kanji and translation closer together in the feature space.

      The more token size, the more context and more precise the feature will be. You should understand that LLM will not look at a single kanji in isolation, rather it can read from the whole page or book. So a single kanji may be statistically paired with the word “king” or whatever, but with context from the previous token it can become another word. And again, if we know the literary art in advance, we could use the different model for the type of language that is usually used for that. You can have a shonen manga translator for example, or a web novel about isekai models. Both will give the best result for their respective types of art.

      I am not saying it will give 100% correct results, but neither does human translation as it will always be a lossy process. But you do need to understand that statistical models aren’t inherently bad at embedding different meanings for the same word. “Ruler” in isolation will be statistically likely to be an object used to measure or a person in charge of a country depending on the model used. But “male ruler” will have a significantly different location in the feature space for the same LLM for the former, or closer for the latter case.

        You’re wrong, the person you are replying to is right and I can say that because I’m learning Japanese and what they are saying makes sense
