Abstractions allow you to focus on the model architecture and data. ## PyTorch Lightning - **The LightningModule**: Decouple the system (architecture, optimization) from the data. - **The Trainer**: Automate loops, checkpointing, logging, and GPU/TPU distribution. - **Callbacks**: Add custom logic (e.g., Early Stopping) without polluting the main loop. ## Keras - **Sequential vs Functional API**: Choosing the right level of complexity. - **Model.fit()**: The power of a single line for training. - **Custom Layers**: Building complex logic while maintaining the high-level API. ## Best Practices - **Consistency**: Use these frameworks to ensure reproducible research and production code. - **Monitoring**: Always integrate with a logger (e.g., TensorBoard, MLflow). --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/jcorpac) — claim your Tome and manage your conversions.
