What is the practical consequence of setting the confidence threshold too low for intent classification?
Answer
Accepting many misclassifications
The confidence threshold acts as a governor on the system's willingness to commit to a classification decision. If this threshold is set too low, the system becomes overly permissive, accepting classifications even when the model's certainty regarding the correct intent is minimal. This results in a high rate of misclassification, where the system inaccurately maps the user's utterance to the wrong goal. Conversely, setting the threshold too high causes the system to reject valid, yet slightly ambiguous, inputs, leading to the frustrating scenario where the user repeatedly receives generic failure responses, such as "I don't understand."
