And then, every parameter value is shifted to the value corresponding to the closest peak in the frequency distribution. As an example, rounding off to the nearest 0.1 fractional coordinate would convert 0.125, a very common coordinate to 0.1 (fig. ), which is not common in our system (fig. ). However, our method would keep 0.125 as it is and instead round off nearby sites to that number (fig. ). The site coordinates of the atoms are one hot-encoded after the rounding-off process. When comparing our final representation with a similar 2D representation proposed by Ren et al. , we emphasize that our approach allows for greater flexibility for incorporating new sites and elements, i.e. we just need to add a new row in the 2-D input matrix. The addition of more elements is more significant of the two as their representation is currently limited up to ternary compounds.
