second commit
complete all translaton for now
Just realized that your work was already ready to be reviewed @umu1729! Please feel free to invite friends to take a look at it. |
@shervinea |
Hi @ytknzw, thanks for your message. It is my understanding that PR #164 is not the same as the current one, right? (deep learning tips and tricks as opposed to machine learning tips and tricks) |
Hi @shervinea, yes, sorry! My misunderstanding! |
No worries @ytknzw, thanks for helping out in seeing what can be already done! By the way, would you be interested in reviewing the translation? |

I suppose that a complete picture

to assess the whole model, so the part in question should be like:

IMHO, the source phrase in English is trying to put the interpretation in layman's terms. Perhaps something similar to yet simpler than "陽性と判定された場合に、真の陽性である確率" from the aforementioned Wikipedia page.

Yep, I think it might be ok with "診断", however when Google searching with combination words "機械学習" and "診断", I look at many headlines related to the medical topics in Japan. The combination words "機械学習" and ("解析" or "分析") pick up headlines related to the machine learning in Japan. Though my approaching to find best translated word not be good one, how do you think about that ?

Yes, you're right. "診断" is a bit weird. This section is about trouble shooting when your model doesn't work as expected. But "分析" sounds like "データ分析". How about "問題分析" ?

As far as I know, "打診" in Japanese had a similar word sense derivation like "diagnostics "in English: from medical usages to common ones.
However, when I see "問題分析", I may think the source phrase in English was "error analysis."

I think 診断
or 診断方法
is better. We need discuss this topic.

Yep, I think it might be ok with "診断", however when Google searching with combination words "機械学習" and "診断", I look at many headlines related to the medical topics in Japan. The combination words "機械学習" and ("解析" or "分析") pick up headlines related to the machine learning in Japan. Though my approaching to find best translated word not be good one, how do you think about that ?

I think there are no major issues on conversion to Japan. Thank you for Hiroki san's great review.
