# Weights & Biases (W&B)

W&B is a machine learning platform for experiment tracking, model visualization, and collaboration. It helps ML teams track experiments, visualize results, and manage models.

## Key Concepts

- Experiment tracking
- Hyperparameter optimization
- Artifact management
- Model registry
- Collaboration features

## Common Use Cases

- ML experiment tracking
- Hyperparameter tuning
- Dataset versioning
- Model comparison
- Team collaboration

## Best Practices

- Log all hyperparameters
- Use consistent naming conventions
- Track datasets as artifacts
- Implement sweeps for hyperparameter search
- Use W&B Tables for visualization
