教授您好:
1. 想請問在 H-ZeroAccess.ipynb 中題目預設的輸出值是正確答案嗎?如下圖(Q5):
2. 如果 1. 的答案為肯定的話,上圖的圖表貌似是用 max-min 標準化的作法(z-score 會有負值),但照理來說表中應該要有值為 1 的數據,想問一下是不是這題答案有誤?(測試後發現要把 max-min 公式中的 max() 換成 sum() 數字才會和上圖一樣!)
謝謝您!
劉宸宇 敬上

Hi,
大部分的作業都沒有要為難大家的意思,
所以按照你自己心裡覺得最理想的方式分析就可以了。
我們提供的只是一種分析的流程和方式,
而且我們認同同學會有自己的分析方法,
所以助教不會根據單一標準答案評分,
而是看分析的流程是不是合理。
提出的解釋是不是有依據和可信。
所以這題的答案是
你可以選擇自己標準化方式。
如果你對標準化這個詞彙有疑義的話,
https://en.wikipedia.org/wiki/Normalization_(statistics)
Wiki上的解釋相當寬鬆,
只要能將原始資料能在同一標準下比較就可以了。
希望有解答你的問題。
同時順便闡釋一下我們作業的評分型態。
Thanks,
HSIAO
