Book Description

Transform your Python skills into deep learning expertise with this comprehensive guide to PyTorch. Whether you're building your first neural network or deploying production AI systems, this book provides everything you need to succeed.

Starting with PyTorch fundamentals?tensors, autograd, and neural network basics?you'll quickly progress to building sophisticated models using the nn.Module class, custom layers, and advanced architectures. Master data handling with PyTorch's dataset and dataloader classes, implement data augmentation, and leverage transfer learning with pre-trained models.

Dive deep into convolutional neural networks for computer vision tasks and recurrent networks (LSTMs, GRUs) with attention mechanisms for sequence processing. Learn to implement complete training loops with proper loss computation, backpropagation, optimization algorithms, learning rate schedules, and regularization techniques.

Take your skills further with advanced topics including custom loss functions and optimizers, mixed precision training, distributed training across multiple GPUs, and automated hyperparameter tuning using grid search, Bayesian optimization, and Optuna. Master model evaluation with cross-validation, confusion matrices, ROC curves, and gradient-based interpretation methods.

The book emphasizes production-ready skills with dedicated coverage of model deployment. Learn quantization and pruning for model optimization, export models using ONNX and TorchScript, and serve them in production environments using Flask and Docker.

Apply your knowledge through hands-on projects: build image segmentation systems with U-Net, implement object detection with YOLO, create NLP applications using Transformers, develop generative models with GANs, and explore reinforcement learning applications.
