AI0-001 AI Concepts and Techniques Practice Question
A natural language processing team wants to build a sentiment analysis model for customer reviews. They have 10,000 labeled reviews and 1 million unlabeled reviews. Which approach would MOST effectively leverage the unlabeled data?
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
✓
Implement a semi-supervised learning algorithm that propagates labels from the labeled to the unlabeled data
Semi-supervised learning uses the small labeled set to guide learning from the large unlabeled set. Self-supervised learning would require a pretext task; fine-tuning a pre-trained model is also valid but semi-supervised directly addresses the labeled-unlabeled mix.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use self-supervised learning to pretrain on the unlabeled data, then fine-tune on the labeled data
Why it's wrong here
Self-supervised learning is a valid approach, but semi-supervised learning is more direct when you have some labels and many unlabeled examples.
- ✗
Train a supervised classifier on only the 10,000 labeled reviews
Why it's wrong here
Ignoring the unlabeled data wastes valuable information that could improve performance.
- ✓
Implement a semi-supervised learning algorithm that propagates labels from the labeled to the unlabeled data
Why this is correct
Semi-supervised learning leverages the unlabeled data by using the labeled data to infer labels for similar unlabeled examples, improving model generalization.
- ✗
Use reinforcement learning with the unlabeled data as rewards
Why it's wrong here
Reinforcement learning requires a reward signal from the environment, which is not available in this static dataset.
