Fig. 1From: Classification of battery compounds using structure-free Mendeleev encodingsVisualisation the 2-cluster (a, c, e) and 5-cluster (b, d, f) results from agglomerative clustering of battery compounds in the computational data set from Ref. [69], encoded using (a, b) one-hot encoding, (c, d) Mendeleev encoding, and (e, f) Mendeleev+ encodingBack to article page
