Question
For the confusion matrix shown, what is the precision for classes A. B, and C? What is the recall for classes A, B, and C? What is the overall accuracy of the system?
Normalized Confustion Matrix | Classifier Output (Computed Classification) Prediction | |||
A | B | C | ||
True Class of the Samples (Input) | A | 0.81 | 0.08 | 0.11 |
B | 0.10 | 0.77 | 0.13 | |
C | 0.11 | 0.15 | 0.74 |
Expert Solution
Step 1
precision for A=0.81/(0.81+0.08+0.11)=0.81/1=0.81
precision for B=0.77/(0.10+0.77+0.13)=0.77/1=0.77
precision for C=0.74/(0.11+0.15+0.74)=0.74/1=0.74
