🚀 Just finished diving into MLG 015 on Performance in Machine Learning! Here's what I learned:
📊 Performance is all about balancing bias and variance. High variance = overfitting (memorizing noise), while high bias = underfitting (oversimplifying data).
💡 Key performance boosters include:
- Collecting more data (especially crucial for neural networks)
- Normalizing features to maintain consistent scales
- Handling missing data intelligently
- Using regularization to balance model complexity
🧠 Remember: Final evaluation metrics are for grading only, not for training. The model needs its own internal compass (loss function) to learn effectively.
