Table 2.
The average improvement and the probabilities associated with a two-tailed, paired Student’s t-test comparing the AUC scores shown in Table 1 of FRaC with (i) LOF, (ii) one-class SVMs, and (iii) the better of LOF and one-class SVMs for each data set.
Approach | Average improvement in AUC score using FRaC | p-value |
---|---|---|
One-class SVM | 0.082 | 0.000038 |
LOF | 0.051 | 0.00062 |
max(LOF,One-class SVM) | 0.022 | 0.088 |
