Comparison of different weighted SVDD methods.
| Detection model | AR (%) | FAR (%) | Training time (s) | Testing time (ms) |
| Static weighted SVDD | 87.2 ± 10.0 | 18.0 ± 5.1 | 0.13 | 0.10 | Adaptive weighted SVDD with a fixed moving window | 98.2 ± 2.7 | 3.7 ± 2.8 | 1.38 | 0.27 | Adaptive weighted SVDD with incremental and decremental strategy | 99.2 ± 2.8 | 1.6 ± 3.8 | 0.26 | 0.31 |
