“…The anomaly detection rates of the existing schemes from Ref. [11–18] are 64%, 97%, 97%, 99%, 98.19%, 98.03%, 99%, and 95.8%, respectively. The proposed SFD algorithm significantly reduces the FPR by 85.88%, 69.91%, 24.21%, 17.32%, 18.78%, 21%, 20.18%, and 31.96%, respectively, when compared to these schemes.…”
