Automated trade industry has developed an AI model which predicts the selling and purchasing of automobiles. During testing, the AI model came up with the following predictions.

How many total tests have been performed in the above scenario?
Calculate precision, recall and F1 Score.

Ans:

(i) The total number of test cases = 60+25+5+10=100

(ii) Precision = TP/(TP+FP)
= 60/(60+25)
= 60/85
= 0.705

(iii) Recall = TP/(TP+FN)
= 60/(60+5)
= 60/65
= 0.92

(iv) F1 Score = 2*Precision*Recall/(Precision + Recall)
= 2*0.705*0.92/(0.705+0.92)
= 1.2972/1.625
= 0.79
