Fig. 9: Heatmaps of structural similarities for 20 HEMs at 300 K and 3000 K.
From: EMFF-2025: a general neural network potential for energetic materials with C, H, N, and O elements
Heatmaps of the 20 HEMs in the training set at 300 K (a) and 3000 K (b), based on Euclidean distance and normalized to characterize structural similarities. The values in the cells represent the similarity between compounds, with colors indicating the correlation values. High values (blue) indicate strong similarity, while low values (red) indicate weak similarity.
