Neural Networks with PyTorch and Lightning AI Part 3: Moving Training Logic into Lightning

Short summary

PyTorch Lightning streamlines neural network training by consolidating optimization and loss calculation into dedicated methods, replacing manual gradient descent loops. Part 3 shows refactoring patterns that reduce boilerplate while preserving control over core training logic. Essential for ML practitioners seeking cleaner, maintainable implementations.

• •Lightning's configure_optimizers() and training_step() consolidate repetitive training code
• •Eliminates manual gradient loops and optimizer management previously scattered across code
• •Enables faster iteration with cleaner, production-ready neural network implementations
