About this video
Embeddings live in high-dimensional space, but we can project them down to actually *see* how meaning clusters together. In this video, I cover: * Why embeddings start in hundreds of dimensions * How dimensionality reduction maps them into 2D * What clustering reveals about semantic similarity * How to interpret distance and grouping visually This is the simplest way to build intuition for how semantic search and retrieval actually work.
