From: Temporal bone radiology report classification using open source machine learning and natural langue processing libraries

Region Inner Middle Outer Mastoid
Accuracy 90 % (+16.0) 90 % (+30.4) 93 % (+7.38) 82 % (+19.0)
F1 Score 0.82 0.85 0.71 0.74
NPV 0.94 0.85 0.93 0.83
PPV 0.82 1.0 0.92 0.80

Specificity 0.94 1.0 0.99 0.90
  1. The values in parenthesis in the accuracy row are the percent difference compared to the majority class. NPV is negative predictive value, PPV is positive predictive value. The best classifiers by region were SVM (linear) for the inner and outer ear, logistic regression for the middle ear, and decision tree for the mastoid
