Distance function | Formula |
|---|---|
Euclidian distance | \(dis(i,j) = \sqrt{\sum \limits _{k=1}^{m}(w_k(p_{ik} - p_{jk}))^2}\) |
Manhattan distance | \(dis(i,j) = \sum \limits _{k=1}^{m}w_k|p_{ik} - p_{jk}|\) |
Canberra distance | \(dis(i,j)= \sum \limits _{k=1}^{m} w_k \frac{|p_{ik} - p_{jk}|}{|p_{ik}|+|p_{jk}|}\) |
Squared chord distance | \(dis(i,j) = \sum \limits _{k=1}^{m}w_k\left(\sqrt{p_{ik}} - \sqrt{p_{jk}}\right)^2\) |
Minkowski distance | \(dis(i,j)= \left[\sum \limits _{k=1}^{m}w_k |p_{ik} - p_{jk}|^q\right] ^{\frac{1}{q}}\) |
