Q21. An AI model has been developed to test specimens of blood/urine/cough etc. to diagnose ailments (diabetes/liver infection etc.). The model was tested on a data-set of about 630 tests and the resulting confusion matrix is as follows:
Reality Yes | Reality No | |
---|---|---|
Prediction Yes | 110 | 60 |
Prediction No | 50 | 410 |
(A) Total cases of True Negative:
(B) Precision, Recall, and F1 Score calculations to be performed.
(A) Total cases of True Negative: 410
(B) Precision, Recall, and F1 Score Calculations:
Precision (Positive Predictive Value) = TP / (TP + FP)
Precision = 110 / (110 + 60) = 0.6471 (64.71%)
Recall (Sensitivity) = TP / (TP + FN)
Recall = 110 / (110 + 50) = 0.6875 (68.75%)
F1 Score = 2 * (Precision * Recall) / (Precision + Recall)
F1 Score = 2 * (0.6471 * 0.6875) / (0.6471 + 0.6875) = 0.6667 (66.67%)
