Embeddings & Vector Databases Explained
Embeddings turn meaning into math. Vector databases make that math searchable at scale.
If you're building anything with AI — semantic search, RAG applications, chatbots, or recommendations — embeddings and vector databases are the foundation. This video breaks down both concepts visually without complex math.
*What you'll learn:*
What embeddings actually are (and the famous "King − Man + Woman = Queen")
How vector databases make similarity search fast
HNSW algorithm explained
A comon mistake that causes silent failures (mixing embedding models)
Real-world applications: RAG, semantic search, recommendations, multimodal search
