Table 2. Test 1: DL-ROM and POD-Galerkin ROM vs. FOM speed-up.

N = 256 N = 1024 N = 4096 N = 16384
FOM vs. DL-ROM 472 536 539 412
FOM vs. POD-Galerkin ROM 3 6 12 22

DL-ROM and POD-Galerkin ROM vs. FOM speed-up by varying N. The DL-ROM speed-up is remarkably higher than the one obtained by using the POD-Galerkin ROM.
