Description
Unlock the power of Large Language Models (LLMs) and bring cutting-edge AI to your projects! This beginner-friendly yet comprehensive course takes you deep into the world of transformer-based models — from foundational architectures like BERT and RoBERTa, to generative giants like GPT and Meta’s LLaMA.But we don’t stop there.You’ll also explore Retrieval-Augmented Generation (RAG) — one of the most powerful methods to enhance LLMs with real-time, context-aware information retrieval. Learn how RAG bridges the gap between static models and dynamic, knowledge-grounded generation — perfect for applications like chatbots, enterprise search, and AI assistants.Whether you’re a beginner Python developer or someone curious about how LLMs really work, this course will give you the theory, hands-on skills, and real-world insights to work confidently with modern AI tools.What You’ll LearnSection 1 – Transformersword embeddingspositional embeddings and encodingself-attention mechanismmaskingmulti-head architecturehow to train a transformer architecturetransformer architectures: GPT, BERT and LLaMASection 2 – Encoder-Only ArchitecturesBERT fundamentalspre-training and fine-tuning the modelthe[CLS] tokenBERT and RoBERTasentiment analysis, text classification and question answering with BERTSection 3 – Decoder-Only ArchitecturesGPT and LLaMA fundamentalsreinforcement learning from human feedback (RLHF)fine-tuning decoder-only architecturesLoRA and QLoRAfine-tuning models on custom datasetSection 4 – Retrieval-Augmented Generation (RAG)what is RAG?semantic search and vector databasesLSH and HNSW algorithmsusing RAG with PDF filesSection 5 – Prompt Engineeringprompt engineering fundamentalszero-shot promptingfew-shot promptingchain of thoughts (CoT)prompt chaining methodsJoin the course today and start your journey into the world of Large Language Models and Retrieval-Augmented Generation.
