WebDetection Rate ¶. The confusion matrix allows to express performance metrics such as the detection rate and the false alarm rate . There is a consensus on the definition of the detection rate ,also called True Positive Rate (TPR): T P R = T P T P + F N. On the contrary, the false alarm rate is not clearly defined. how dirty is a public bathroom floor
