A vectorial tree distance measure [PDF]

open access: yesScientific Reports, 2021
Abstract A vectorial distance measure for trees is presented. Given two trees, we define a Tree-Alignment (T-Alignment). We T-align the trees from their centers outwards, starting from the root-branches, to make the next level as similar as possible.
