AI0-001 AI Concepts and Foundations Practice Question
A team is training a deep learning model for natural language processing using a large corpus. They notice the model has a very high number of parameters and training is slow. Which technique can reduce the number of parameters without significant performance loss?
⚠ Common exam trap
Test-takers frequently confuse regularization techniques (like dropout) or training speed optimizations (batch size, learning rate) with actual parameter reduction, which only embedding compression directly achieves.
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
✓
Apply embedding compression
Embedding compression reduces the dimensionality of the embedding layer, which often contains the majority of the model's parameters in NLP tasks. By using techniques like low-rank factorization or pruning, the model retains most of its representational power while significantly decreasing the parameter count and training time.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Apply embedding compression
Why this is correct
Embedding compression reduces the dimensionality of embedding layers, directly reducing parameters with minimal impact on performance.
- ✗
Add more dropout layers
Why it's wrong here
Dropout adds regularization but does not reduce the number of parameters; it only temporarily ignores neurons during training.
- ✗
Use a larger batch size
Why it's wrong here
Larger batch size affects training speed but does not reduce the number of parameters.
- ✗
Increase learning rate
Why it's wrong here
Learning rate adjustments do not change model size; they affect convergence speed.
