🎯 Best Practices

  1. Data Quality: Clean and well-labeled data is crucial
  2. Preprocessing: Tokenization, lowercasing, remove noise
  3. Embeddings: Use pre-trained embeddings (Word2Vec, GloVe, BERT)
  4. Fine-tuning: Start with pre-trained models
  5. Evaluation: Use appropriate metrics (F1 for imbalanced data)
  6. Interpretability: Explain model predictions
  7. Bias: Be aware of biases in training data
  8. Testing: Test on diverse examples and edge cases
