Fault-Level Grading of Photovoltaic Cells Employing Lightweight Deep Learning Models

Table 7

Multiclass classification results of the deep ANN using original data: (a) GLCM features and (b) LBP features.

		Actual class
		Healthy	Less faulty	Medium faulty	Full faulty
(a) GLCM features
Predicted class	Healthy	194	39	12	47
	Less faulty	0	0	0	0
	Medium faulty	0	0	0	0
	Full faulty	32	6	4	60
Classwise accuracy		85.8%	0%	0%	56.1%
Overall accuracy		64.5%
(b) LBP features
Predicted class	Healthy	196	18	6	34
	Less faulty	0	21	8	5
	Medium faulty	0	0	0	0
	Full faulty	30	6	2	68
Classwise accuracy		86.7%	46.7%	0%	63.5%
Overall accuracy		72.3%
