Figure 2. (A) Result of the k-means clustering algorithm where each color denotes a cluster in the reduced composition space. Here, PC1 and PC2 are the two principal components obtained after the Principal Component Analysis decomposition of the 19-dimensional space; (B) a 3D plot of the distribution of the alloys in the thermophysical property space of ρ_p, k_p, c_p at 300 K, indicated by the blue circles. The projection of these points on the pairwise planes of ρ_p - c_p, c_p - k_p, k_p - ρ_p are indicated by the yellow, green, and red triangles.
