2026 Complete Learning Roadmap for Data Science and Generative AI: From SQL to Agentic AI

This open-source GitHub project 《Data-Science-Generative-AI-Roadmap-2026》 (released on 2026-06-12), maintained by ramkrishnakasbe, provides a structured learning roadmap from SQL to Agentic AI. It covers data science fundamentals, core machine learning, cutting-edge generative AI, and other content, with supporting notes, interview preparation, and practical projects—it is an end-to-end learning guide.

In 2026, the demand for AI talent is soaring, but beginners often struggle with issues such as learning sequence, core skill selection, and translating theory into practice. This open-source project addresses these pain points by providing a systematic knowledge system to help learners build comprehensive capabilities.

Stage 1: Data Science Fundamentals: SQL (from basics to performance optimization), Python (core syntax + data processing/visualization libraries), statistics and mathematics (descriptive statistics, probability theory, linear algebra, etc.); Stage 2: Core Machine Learning: Supervised/unsupervised/reinforcement learning algorithms (linear regression, decision trees, etc.), model evaluation metrics, feature engineering, cross-validation and other practical skills; Stage 3: Cutting-Edge Generative AI: LLM basics (Transformer architecture, GPT/BERT), RAG (vector databases, frameworks like LangChain), Agentic AI (design patterns, multi-agent collaboration).

1. Structured Notes: Each topic is digested and organized to save filtering time;
2. Interview Preparation: Systematically compiled common questions for data science/AI roles (technical, case, behavioral interviews);
3. Hands-On Implementation: End-to-end practical projects covering the full process from data acquisition to deployment.

• Beginners: Follow the sequence step by step, do not skip the basics;
• Experienced Practitioners: Learn selectively based on knowledge gaps (e.g., traditional data scientists focus on generative AI);
• Job Seekers: Prepare cases with project experience and use the interview preparation section for review.

Covered tools include:

• Data processing: Pandas, NumPy, Polars;
• Machine learning: Scikit-learn, XGBoost, LightGBM;
• Deep learning: PyTorch, TensorFlow;
• Large model development: Hugging Face Transformers, LangChain, LlamaIndex;
• Vector databases: Pinecone, Chroma, Weaviate;
• Deployment tools: Docker, FastAPI, Streamlit.

This roadmap balances classic core knowledge and cutting-edge technologies, helping learners avoid information overload. The role of data scientists is evolving from analyzing historical data to building intelligent systems; mastering the content of this roadmap can help adapt to this transition. It is recommended to use the roadmap as a framework, build a personalized path based on interests, and continue learning and practicing.
