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.
