### [1] basestyle


範例:
相同大類: Misty, 但**捲度s/ss不同**, **瀏海不同**

- (unique) Id: **unique** id for each image, categorical data.
- (unique) Path: path of an image, string data.
- (identity/NOT unique) Source: identity of an image (**not unique** for each image since we have **multiple images for each identity**), categorical data.
- 不是所有的source都會有after/before。
- 來自同一個source的圖片張數可能從個位數張到百張都有可能。
舉例: source: JSS222755共有112張。
- basestyle 共有31類別。
