🔧 Scaling Methods Comprehensive Analysis 🔧 縮放方法綜合分析

Min-Max Normalization 最小最大正規化

Scales features to a fixed range [0,1]. Preserves relationships but sensitive to outliers. 將特徵縮放至固定範圍[0,1]。保留關係但對離群值敏感。

X_scaled = (X - X_min) / (X_max - X_min)

✓ Best for: Neural networks, image processing ✓ 最適合：神經網路、圖像處理

Z-Score Standardization Z分數標準化

Centers data around 0 with unit variance. Assumes normal distribution. 將資料以0為中心，單位變異數。假設正態分佈。

X_scaled = (X - μ) / σ

✓ Best for: PCA, SVM, linear regression ✓ 最適合：PCA、SVM、線性回歸

Robust Scaling 穩健縮放

Uses median and IQR. Less affected by outliers than other methods. 使用中位數和四分位距。比其他方法較少受離群值影響。

X_scaled = (X - median) / IQR

✓ Best for: Data with outliers, financial data ✓ 最適合：含離群值資料、金融資料

Unit Vector Scaling 單位向量縮放

Scales samples individually to unit norm. Good for text analysis. 將樣本個別縮放至單位範數。適合文本分析。

X_scaled = X / ||X||

✓ Best for: Text analysis, sparse data ✓ 最適合：文本分析、稀疏資料
