Step-by-Step Solution
Solution:
Step 1: Identify class imbalance issue
Distinguishing similar classes requires sufficient training examples for each.Step 2: Consider augmentation benefits
Data augmentation can increase minority class samples, improving model discrimination.Step 3: Evaluate other options
Reducing classes loses granularity; dropout helps generalization but not class distinction; unsupervised clustering doesn't directly improve supervised class separation.Final Answer:
Use data augmentation to increase examples of 'very positive' class -> Option AQuick Check:
More data for subtle classes improves model distinction [OK]
Quick Trick: Augment minority classes to improve fine distinctions [OK]
Common Mistakes:
MISTAKES- Reducing classes instead of improving data
- Confusing regularization with class balance
- Relying on unsupervised methods for supervised tasks
