Fault localization is a core element in fault management. Many fault reasoning techniques
use deterministic or probabilistic symptom-fault causality model for fault diagnoses and
localization. Symptom-Fault map is commonly used to describe Symptom-Fault causality
in fault reasoning. However, due to lost and spurious symptoms in fault reasoning systems
that passively collect symptoms, the performance and accuracy of the fault localization
