對,老師有回答,反正就是 loss function 可以自己設立,只要合理(當然還要有效,比如提供不錯的梯度等),所以自己設立的數學式,有可能有負值。

礼拜五和礼拜六会不会是因为时差?不知道youtube data analysis 用的时间是PST还是台湾的时间? 有可能台湾的周末,会不会是对应了PST的周五周六?

I'm not sure it's the teacher, but listening in Chinese, the explanation is very simple and clear....but none of the English speaking instructors can teach this topic well. They are all stuck on jargons and unable to explain what each jargon really means. Perhaps it's a language thing. In Chinese, the Chinese characters making up the jargon phrase would, most of the time, indicate what the meaning of the jargon is, but in English the jargon does not indicate the meaning...it's just a vocabulary and many times it's completely a new vocabulary. This is an interesting observation.....perhaps this makes learning in Chinese easier than learning in English ? So Chinese people are smarter because of this learning effect ? I'd like to hear your comments.
