Fig. 9: Comparison of the topogivities of ref. 31 with those obtained here for 54 elements.
From: Machine learning on multiple topological materials datasets

The color code refers to ΔτE, a measure of their relative difference, as defined by Eq. (2). When the signs of the two topogivities are different, the value of ΔτE is negative, and thus the element is highlighted in blue.
