Table 4 Best classifier confusion matrices by ear region

Inner Ear: SVM Linear Kernel			Middle Ear: Logistic Regression
	Predicted Label			Predicted Label
Actual Label	Normal	Abnormal	Actual Label	Normal	Abnormal
Normal	101	7	Normal	87	0
Abnormal	7	31	Abnormal	15	44
Outer Ear: SVM Linear Kernel			Mastoid: Decision Tree
	Predicted Label			Predicted Label
Actual Label	Normal	Abnormal	Actual Label	Normal	Abnormal
Normal	124	1	Normal	83	9
Abnormal	9	12	Abnormal	17	37

Test set confusion matrices for best learning algorithm for each ear region. The confusion matrices provide the true and false counts for normal and abnormal documents as labeled by the classification algorithm
