Question
Your organization, Nutex Inc., is developing a language understanding app for a virtual assistant that helps users manage their to-do lists. You have defined intents such as “AddItem,” “RemoveItem,” “MarkComplete,” and “ViewList.” You have populated these intents with sample utterances and created entities to capture task details (e.g., task name, due date, priority). You have trained and evaluated the model.
After training the model, you notice that the “AddItem” intent has a low F1 score in the evaluation results. What should you do to improve the model’s performance for this intent?
A. Delete the “AddItem” intent and create a new intent with a different name.
B. Add more utterances to the “AddItem” intent, especially focusing on variations in how users might express adding a task.
C. Ignore the evaluation results and publish the language understanding app.
D. Immediately deploy the model to a production environment and gather real user feedback.
Answer
B. Add more utterances to the “AddItem” intent, especially focusing on variations in how users might express adding a task.
Explanation
In the given scenario, you would add more utterances to the “AddItem” intent, especially focusing on variations in how users might express adding a task. This will help improve the model’s F1 score which measures the performance of the model. By incorporating a diverse range of example phrases that users might use to express adding tasks, you help the model better recognize and respond accurately to different ways users might phrase this intent. Increasing the number of training examples for this intent reduces the likelihood of misclassification and improves the model’s overall performance.
You would not immediately deploy the model to a production environment and gather real user feedback in the given scenario. Although gathering real user feedback is valuable, it is important first to address any model weaknesses observed during testing. Improving the model’s performance based on evaluation results will help ensure that users experience accurate and reliable responses from the start.
Deleting the “AddItem” intent and creating a new intent with a different name will not improve the model’s performance for this intent. This would lead to a loss of the existing training data associated with this intent. Renaming or recreating an intent does not inherently improve model performance.
Ignoring the evaluation results and publishing the app will not improve the model’s performance for this intent. The evaluation results are crucial for understanding the model’s weaknesses and areas where it needs improvement. Ignoring low performance in evaluation results could lead to poor user experience and inaccurate responses when the app is deployed to production.
