A lock-and-dam 'needs a tow assist' flag treats a missed true case as far worse than an extra false launch. Accuracy is not the decision. Which metric should they optimize?
Select an answer to reveal the explanation.
Short Explanation
A missed tow assist is the expensive miss. Optimize recall, because a false negative costs more than an extra false launch. Precision is the other cost, accuracy hides the miss, and Rekognition is not the metric.
Full Explanation
Choose recall when false negatives are the costly error and precision when false positives are. A missed tow assist is a false negative, so recall is the metric. Accuracy hides that cost. Rekognition is not an evaluation choice.
