## Data preparation

- [[03 Learning/Data Science/Data Cleaning]]
- [[03 Learning/Data Science/Standardizing vs Normalizing]]

## Connections

- Data cleaning should happen before [[03 Learning/Deep Learning/Cross-Validation]].
- [[03 Learning/Data Science/Standardizing vs Normalizing]] is especially important for neural networks and distance-based models.
