In one to two sentences, why might a small dataset favor hand-engineered features over a large neural network?
Question: Based on the concept that scale drives deep learning progress, briefly explain why hand-engineered features can outperform large neural networks when data is scarce.
Sample answer: When data is scarce, large neural networks lack enough examples to learn useful patterns on their own, so their advantage from scale is not available. Hand-engineered features inject human domain knowledge directly into the model, compensating for the missing data and often yielding better performance in this small-data regime.
Key points:
- Neural networks rely on scale to perform well
- Small data limits the benefit of scale
- Hand-engineered features encode human knowledge
- This can outperform neural networks in low-data settings
Rubric: Full credit for stating that neural networks need large data to benefit from scale and that hand-engineered features substitute human knowledge when data is limited. Partial credit for a vague or incomplete explanation.
