Foundational Transformers for Natural Language Processing

Transformer models have revolutionized how we process language, powering today's most advanced AI systems. If you want to understand how these architectures work from the ground up without getting lost in overly complex academic jargon, this course is for you. This text-based course guides you through the inner workings of Transformer models, from basic attention mechanisms to deploying pre-trained models. You will transition from a curious learner to a practitioner capable of selecting, adapting, and implementing modern NLP architectures for real-world tasks. What you'll learn: 1. Understand the foundational architecture of Transformers, including self-attention, encoders, and decoders. 2. Implement core components of the Transformer model using PyTorch code snippets. 3. Leverage Hugging Face libraries to load, configure, and utilize pre-trained models. 4. Apply parameter-efficient fine-tuning techniques like LoRA to adapt models to specific datasets. 5. Explore modern retrieval-augmented generation (RAG) patterns and prompt engineering basics. 6. Analyze model performance and troubleshoot common deployment challenges. You will begin with essential terminology and the mathematical intuition behind attention mechanisms before moving on to hands-on code examples, practical fine-tuning workflows, and modern integration patterns. This course is designed for beginners in deep learning and NLP. A basic familiarity with Python and neural network concepts is helpful, but no prior experience with Transformers is required.
