README:
Welcome to the Language AI Engineering Lab — a comprehensive, structured repository designed to guide you from human language fundamentals and NLP through Transformers, Large Language Models, and into production-ready Language AI systems.
Whether you are starting from the basics or aiming to build scalable, real-world Ganerative AI applications, this lab offers hands-on learning paths, practical implementations, and end-to-end projects that cover the entire Language AI engineering lifecycle — from text processing and model architectures to retrieval, agents, orchestration, evaluation, and deployment.
Generative AI is a class of artificial intelligence systems designed to create new content—such as text, images, code, audio, or video—based on patterns learned from data.
It is not the same as traditional Machine Learning, which typically focuses on prediction or classification tasks (e.g., forecasting values or assigning labels).
Generative AI models learn the underlying structure of data and use it to generate novel, coherent outputs, often in a flexible and interactive way.
In this repository, you will explore in-depth concepts of Generative AI, including diagrams, illustrations, code and notebook examples, references, and curated videos to support and accelerate your learning.
Important: This repository focuses on Generative AI. If you are looking to learn Machine Learning, you can find it in this Machine Learning repository.
It is important to understand the meaning and purpose of each section:
Foundations of NLP, NLU, and NLG: tokenization, embeddings, intent extraction, entity recognition, and text generation.
Deep dive into transformers: attention, embeddings, positional encoding, feedforward layers, and why transformers work.
Core LLM concepts, architectures, training strategies (fine-tuning, RLHF), and evaluation foundations.
Zero-shot, one-shot, few-shot prompting, reasoning patterns, prompt templates, and optimization techniques.
Managing LLM context windows, conversation state, memory, truncation strategies, and structured outputs.
End-to-end Retrieval-Augmented Generation pipelines: indexing, chunking, embedding, retrieval, reranking, grounding, and response synthesis.
Designing context as a system: instruction hierarchies, memory fusion, grounding strategies, safety constraints, and cost-aware assembly.
Metrics, prompt testing, regression testing, hallucination measurement, latency, cost tracking, and tracing.
Failure modes, hallucination taxonomy, detection strategies, grounding techniques, and mitigation patterns.
Standardized tool and data access via MCP, custom servers, and secure integrations.
Workflow orchestration with LangChain, LangGraph, Semantic Kernel, LangFlow, LangSmith, and LangFuse.
Autonomous agents, planning, reasoning loops, tool use, and multi-agent collaboration.
Vision-language models, audio-text models, multimodal fusion, and cross-modal reasoning.
CI/CD, deployment, monitoring, observability, scaling, and cost optimization.
Dataset lifecycle, cleaning, versioning, labeling, and synthetic data generation.
Speech-to-text, text-to-speech, dialogue management, and real-time IVR orchestration.
Practical and applied hands-on projects.
Jupyter notebooks for experiments and demonstrations.
Utility scripts and helper functions.
