A note on rating

Rating can be misleading. It was a casual design and is heavily tied to Mortal's implementation details, which most users are unfamiliar with, and there are difficulties and challenges in spreading such knowledge. This feature was not my original intention in creating this tool, nor is it a main feature, so I didn't put much thought into it.

Rating has never been used in training, either directly (like a loss function) or indirectly (like f1-score). It has no impact on nor does it reflect the training result.

I am concerned that this rating value is diverting everyone's attention from more important matters - those individual wwyd scenes. In the end, rating is merely an average min-max scaled value without calibration or confidence intervals. Moreover, it is directly associated with a specific set of hyperparameters/parameters, making it unsuitable as a good reference. Despite this, it has oddly become a popular feature, which worries me a bit. Thus I have placed it in the "advanced options" section because it is indeed an advanced feature that requires knowledge of the background to use correctly.

Besides, the calculation of rating is based on the details table, but that table is just a by-product of the AI, serving as a means to an end, not an end in itself. Focusing too much on building the table may hinder the development of a stronger AI. In a future version, rating as well as the details table may be altered or even removed.

1. --player-id <ID>
검토할 플레이어의 ID를 0~3 이내의 숫자로 지정합니다. 천봉 패보 URL에서 &tw= 뒤의 숫자로 구분할 수 있습니다. 즉, 동쪽에서 E1에 앉아 있는 플레이어는 0이고 그 자리에서의 하가(오른쪽)은 1, 상가(왼쪽)은 3입니다. 이 옵션을 숫자로 직접 지정하게 되면 URL에 포함된 플레이어 ID는 무시하게 됩니다.
2. Mortal vs Mortal 을 참조하세요.
3. --temperature <TEMP>
모탈 엔진 전용. 표시된 값에만 영향을 미치고 작업 순서나 등급은 변경되지 않습니다. 자세한 내용은 FAQ 을 참조하세요.
4. --kyokus <LIST>
특정 국을 지정합니다. 공백으로 두면 모든 국을 리뷰합니다. 예시 : E1,E4,S3.1 예시의 경우 동1국, 동4국, 그리고 남3국 1본장을 리뷰합니다.

FAQ / 자주 묻는 질문

이 프로그램의 FAQ는 여기를 참고하세요.

패보를 복기하는데 얼마나 걸리나요?

Mortal 엔진의 경우 일반적으로 10초 미만입니다.

akochan 엔진의 경우 게임의 길이에 따라 10분에서 60분까지 경과합니다.

패보 복기 보고서는 온라인 서버에 얼마나 오래 보관되나요?

15일이 지난 결과 페이지는 서버에서 자동으로 삭제됩니다. 필요한 경우 저장하십시오.

(Mortal) I find it makes some strange suggestions that I believe are wrong.

First of all, the AI is not perfect. You could try again but with the more human-like network ("3.0"), which usually produces more moderate or easier-to-understand suggestions than the others.

It may seem at times that this network is stronger, but it's important to remember that statistics are more reliable than subjective feelings. If you have any doubts about the experiment or the statistics, feel free to help review the code.

Is there a Discord server?

No. If you have any questions, please feel free to discuss them in the discussion section of the corresponding repos on Github.
