Step-by-Step Solution
Solution:
Step 1: Understand Skip-gram vs CBOW
Skip-gram performs better on rare words by predicting context from center word.Step 2: Role of min_count
Lowering min_count includes more rare words in the vocabulary for training.Step 3: Combine settings
Using Skip-gram with low min_count helps capture rare word semantics effectively.Final Answer:
Use Skip-gram (sg=1) with a low min_count value to include rare words in training. -> Option CQuick Check:
Skip-gram + low min_count = better rare word embeddings [OK]
Quick Trick: Skip-gram + low min_count captures rare words better [OK]
Common Mistakes:
MISTAKES- Assuming CBOW is better for rare words
- Setting min_count too high excludes rare words
- Disabling negative sampling harms training quality
