Performance of the fully convolutional neural network for NFT detection

Training/Validation Testing
Metrics Total Total PART CTE PSP
Recall, TP/(TP + FN), sensitivity 0.91 0.92 0.96 0.78 0.88
Precision, TP/(TP + FP), PPV 0.80 0.72 0.77 0.75 0.63
F1 score (harmonic mean of precision and recall) 0.85 0.81 0.85 0.77 0.73

F1 score harmonic mean is calculated as 2*Precision*Recall/(Precision + Recall); NFT neurofibrillary tangle; PART primary age-related tauopathy; CTE chronic traumatic encephalopathy; PSP progressive supranuclear palsy
