Learn embeddings, similarity search, HNSW, IVF, semantic search, RAG, and recommender systems with hands-on examples.
What you'll learn
⚡ Explain what embeddings are and how they enable similarity search.
⚡ Learn how to choose and fine-tune embedding models for custom applications.
⚡ Learn how vector databases work in terms of indexing & retrieval.
⚡ Familiarize yourself with the vector database landscape and different applications.
Requirements
❗ Basic Python knowledge recommended, but step-by-step coding lessons are provided.
❗ No prior experience with embeddings, vector databases, or similarity search is required.
Description
Embeddings and vector databases are the foundation of many modern AI applications — from semantic search to retrieval-augmented generation (RAG) and personalized recommendations. This course takes you from the core concepts to production-ready solutions, following a structured, project-based approach.
InSection 1, you'll build deep intuition about embeddings: what they are, how they are produced with Sentence Transformers, and how similarity metrics like cosine, Euclidean, and dot product work. You'll then apply these concepts to build a mini search engine.
InSection 2, you'll learn how to choose and customize embedding models. We'll cover how embedding models are formed, how to evaluate them using the MTEB benchmark, and how to use multimodal embeddings. You'll then explore fine-tuning with contrastive loss.
InSection 3, we go under the hood of vector databases. You'll learn the theory behind indexing methods like HNSW and IVF through clear visual explanations, followed by coding demos showing them in action.
InSection 4, we turn theory into practice. You'll explore the vector database landscape, implement semantic search and dense retrieval, integrate embeddings into RAG pipelines, and build recommender systems using Pinecone — all with reproducible Python notebooks.
By the end of this course, you'll have both the conceptual understanding and the hands-on skills to confidently build and deploy AI applications powered by embeddings and vector databases.
Who this course is for
⭐ Data scientists, ML engineers, and software developers exploring vector search.
⭐ AI practitioners and enthusiasts who want to apply embeddings in real-world projects.
⭐ Professionals interested in semantic search, RAG, and recommender systems.
