Measure	Formula
Euclidean^[24] ↓	$d i s = \sqrt[]{\sum_{j = 1}^{c} (p_{j} - q_{j})^{2}}$
S?rensen^[25] ↓	$d i s = \frac{\sum_{j = 1}^{c} \|p_{j} - q_{j}\|}{\sum_{j = 1}^{c} \|p_{j} + q_{j}\|}$
Squard χ^2[26] ↓	$d i s = \sum_{j = 1}^{c} \frac{(p_{j} - q_{j})^{2}}{p_{j} + q_{j}}$
Kullback?Leibler (KL)^[13] ↓	$d i s = \sum_{j = 1}^{c} p_{i} l n \frac{p_{i}}{d_{i}}$
Intersection^[27] ↑	$s i m = m i n (p_{j} - q_{j})$
Fidelity^[28] ↑	$s i m = \sum_{j = 1}^{c} \sqrt[]{p_{j} q_{j}}$
