Fig. 12: Concept visualization example.
The first row shows SEM images of two different steels and the second row shows their characteristic textures patterns generated from a CNN. Specifically, these synthetic texture patterns illustrate concepts learned in CNN filters through activation maximization. Results suggest that important synthetic texture patterns show interesting abstractions of the corresponding material microstructure. Figure reprinted from ref. 95 with permission.
