Classification performance indices (Thai)

Formulae of binary classification performance indices, basic interpretation and trade-off

Errata:
41:56 I said as t increases, TPR increases, which is WRONG. I meant to say that as t increases TPR decreases (and surely, FNR = 1-TPR, would increases)

01:00 Confusion matrix, TP, TN, FP, FN
04:25 Sensitivity, specificity, accuracy
16:00 Prevalence, precision, F1 score
25:00 Interpretation of indices in detecting brain tumor
34:48 Trade-off classification in information retrieval
45:00 Receiver operating characteristic (ROC)
55:00 Precision-Recall curve
