데이터 타입별 변환 기법, 피처 선택 방법, 피처 스토어 설계 가이드.

## 수치형 변환

### 스케일링

| 방법 | 공식 | 적합 | 부적합 |
|------|------|------|--------|
| StandardScaler | (x - μ) / σ | 정규분포, SVM, 로지스틱 회귀 | 이상치 민감 |
| MinMaxScaler | (x - min) / (max - min) | [0,1] 필요, 신경망 | 이상치 민감 |
| RobustScaler | (x - Q2) / (Q3 - Q1) | 이상치 존재 | — |
| PowerTransformer | Box-Cox / Yeo-Johnson | 왜도 큰 분포 | 음수값(Box-Cox) |
