A tool-library chat is judged by how often a browser adds a paid weekend reservation. The team is not judging it by BLEU. Which value metric is this?
Select an answer to reveal the explanation.
Short Explanation
Think of how often a chat turns into a paid weekend reservation. That is conversion. BLEU, RMSE, and a token invoice without the booking are not the action.
Full Explanation
Conversion rate measures how often a visitor takes the desired action, here adding a paid reservation. BLEU and RMSE are lab language or regression scores, not that action. A token invoice without a completed reservation is cost, not conversion.
