AI-103 Text Analysis Practice Question
You are troubleshooting a custom text classification model that exhibits high training loss and low validation accuracy, indicating severe model underfitting. What adjustment should you make to improve the model?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the diversity and volume of training data and ensure model training is allowed to complete fully.
Underfitting occurs when a model is too simple or hasn't learned enough patterns. Increasing training iterations (epochs) or adding more descriptive features and training data helps resolve underfitting.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Lower the confidence score threshold to 0.01.
Why it's wrong here
Changing inference thresholds does not fix model underfitting.
- ✓
Increase the diversity and volume of training data and ensure model training is allowed to complete fully.
Why this is correct
Underfitting is addressed by providing more training data and ensuring adequate model learning capacity.
- ✗
Reduce the training dataset size by 90%.
Why it's wrong here
Reducing training data will worsen underfitting.
- ✗
Switch the resource pricing tier from Standard to Free.
Why it's wrong here
Pricing tiers do not change model training algorithms.
