Table 2 Confusion matrix of the physics-based approach on 228 data points

From: Classification of failure modes of pipelines containing longitudinal surface cracks using mechanics-based and machine learning models

(a) Scenario #1
Total number of samples = 228		Predicted failure mode
		Rupture (190)	Leak (38)
Actual failure mode	Rupture (102)	n_TP = 98	n_FN = 4
	Leak (126)	n_FP = 92	n_TN = 34
(b) Scenario #2
Total number of samples = 228		Predicted failure mode
		Rupture (202)	Leak (26)
Actual failure mode	Rupture (102)	n_TP = 101	n_FN = 1
	Leak (126)	n_FP = 101	n_TN = 25
