-
Foundations of Data & AI
8 weeksGoals
- Achieve proficiency in Python for data manipulation and API interaction.
- Understand core concepts of databases (SQL/NoSQL), data modeling, and basic information retrieval.
- Learn the fundamentals of Large Language Models, transformers, and the concept of embeddings.
Resources
- Python for Data Analysis (Wes McKinney book)
- Hugging Face NLP Course
- LangChain documentation & introductory tutorials
MilestoneCan build a simple script that queries a vector store (like FAISS or Chroma) using an LLM to answer questions from a small set of documents.
-
Core RAG & Knowledge System Building
12 weeksGoals
- Master advanced RAG techniques: chunking strategies, metadata filtering, re-ranking, and query transformation.
- Gain hands-on experience with a production vector database (e.g., Pinecone, Weaviate).
- Learn to evaluate RAG systems using standard metrics (context precision, faithfulness).
- Understand basic knowledge graph principles and graph database query languages (Cypher).
Resources
- LlamaIndex documentation for advanced RAG patterns
- Weaviate/Pinecone technical blogs and tutorials
- Neo4j GraphAcademy courses
- Papers: 'RAPTOR', 'Self-RAG', 'CRAG'
MilestoneCan design, implement, and evaluate a multi-step RAG pipeline for a specific domain (e.g., legal contracts, technical documentation) using a vector database and graph store.
-
Systems Architecture & Productionization
12 weeksGoals
- Learn to design scalable, secure, and maintainable knowledge system architectures on a major cloud provider.
- Implement monitoring, logging, and evaluation (MLOps) for live knowledge systems.
- Understand data pipeline orchestration for ingestion and updates.
- Study cost optimization and latency reduction techniques.
Resources
- AWS Well-Architected Framework for ML
- MLOps Zoomcamp (DataTalks.Club)
- Docker and Kubernetes for Beginners
- Practical tutorials on building production RAG with LangServe or FastAPI
MilestoneCan architect and deploy a cloud-native knowledge system with CI/CD, monitoring, and automated evaluation, ready for production traffic.
-
Specialization & Advanced Integration
16 weeksGoals
- Deep dive into advanced topics like agentic RAG, graph-based reasoning, and fine-tuning embedding models.
- Learn to integrate knowledge systems with other AI agents and enterprise software (ERP, CRM).
- Explore cutting-edge research in knowledge representation and neuro-symbolic AI.
- Build a portfolio of complex, end-to-end projects.
Resources
- Graph Neural Network courses (Stanford CS224W)
- Advanced LangChain modules on Agents & Memory
- Research papers on HyDE, ColBERT, and Sentence-Transformers
- Enterprise integration patterns and API design books
MilestoneCan lead the design of a hybrid knowledge system combining RAG, knowledge graphs, and fine-tuned models to solve a complex, multi-faceted business problem.
Practice Projects
Apply your skills with hands-on projects. Ordered by difficulty.
Build a Domain-Specific Q&A Bot over Technical Documentation
BeginnerCreate a simple RAG system using LangChain and a FAISS vector store that can answer questions from a set of Markdown documentation files (e.g., Python docs or a GitHub README). Focus on clean ingestion, good chunking, and basic evaluation.
Develop a Hybrid Search Engine for a Research Paper Corpus
IntermediateBuild a system that combines dense vector search (e.g., with Sentence-Transformers) and sparse keyword search (BM25) over a collection of academic papers. Implement a re-ranking model to merge the results. Deploy it as a FastAPI service.
Architect a Knowledge-Graph-Enhanced RAG System for Financial News
AdvancedDesign a system that ingests news articles, uses an LLM to extract entities and relationships into a Neo4j graph, and uses the graph to enhance retrieval for complex queries like 'How are Company A and Company B connected in recent M&A activity?' Provide a detailed architecture document and a working prototype.
