Reconstruction of statistically novel faces. These faces are radically different from sample set (Figure 3a) used to create the tensorfaces. (ai) Reconstructing Yoda using tensorfaces with different complexities. (aii) Relative reconstruction error for Yoda as a function of tensorface complexity (rank) (dashed line), as well as relative reconstruction error for the test face set (solid line). The solid line is duplicated from Figure 11b. Reconstruction error decreases as a function of tensorface complexity for familiar faces (solid) but increases for the statistically novel face (dashed). Each line independently normalized so that the maximum equals one. (bi) Reconstructing chimp using tensorfaces with different complexities. (bii) Relative reconstruction error for chimp as a function of tensorface complexity (rank) (dashed line), as well as relative reconstruction error for the test face set (solid line). The solid line is again duplicated from Figure 11b. As with Yoda, reconstruction error decreases as a function of tensorface complexity for familiar faces (solid) but increases for the statistically novel face (dashed).
